Digital Generators and Builders
Digital generators and builders simplify session prep by instantly creating maps, dungeons, NPCs, loot, and even custom rules. Here’s how they can speed up your homebrew creation process.
Donjon provides a collection of free, web-based tools that can generate everything from fractal world maps to detailed NPCs complete with portraits and stats. It supports a wide range of systems, including D&D 5e, D&D 5.5 (the 2024 update), Pathfinder, Alien RPG, and Star Wars d20. One standout feature is the "Five Room Dungeon" generator, which creates a full dungeon framework in seconds. Another favorite is the Markov Name Generator, which crafts unique, thematic names using your custom source lists.
Donjon Generators
Donjon excels at procedural generation, relying on fixed algorithms to create content like maps, calendars, and encounters. It handles the time-consuming tasks of populating dungeons with traps, monsters, and treasure, saving game masters hours of prep work. Whether you need random adventures or even weather forecasts for your campaign, Donjon has you covered. Plus, it’s entirely web-based and free - no downloads or subscriptions required.
Foundry VTT Modules
Foundry VTT is a one-time purchase platform priced at $50, with no ongoing subscription fees. It supports modules that act as plug-ins, allowing you to package homebrew content - like characters, items, and scenes - into compendium packs for easy reuse across campaigns. According to Foundry Virtual Tabletop, creating a custom game system in Foundry requires basic coding knowledge in JavaScript, HTML, and CSS. For those not ready to dive into coding, the "Simple Worldbuilding" system offers a beginner-friendly option while more complex systems are being developed.
One standout feature is the Random Procedural Creations module, which can generate over 50 types of homebrew content - everything from bosses and cults to magic items and quests - directly within the VTT. It even supports simple chat commands and includes up to 5 free AI requests daily.
Demiplane Homebrew Features
AI-driven tools like Dndgen use machine learning to create balanced outputs based on natural language descriptions. These tools can automatically generate monster stat blocks or NPC backstories with minimal input. Best of all, Dndgen offers a free tier that doesn’t require a credit card to get started.
Online Platforms for Homebrew Content
Online platforms make it easier to design, format, and share homebrew content, offering tools that range from integrated digital sheets to polished PDF outputs. Let’s take a closer look at two standout platforms tailored for different homebrew needs.
DNDBeyond Homebrew Creator
DNDBeyond's Homebrew Creator is a user-friendly tool, perfect for beginners. It provides guided forms to help you create custom backgrounds, feats, magic items, monsters, species, spells, and subclasses. These creations integrate seamlessly with the platform’s Character Builder, digital sheets, and Maps VTT. Once you’ve designed your content, it’s stored in a "Homebrew Collection", functioning like your personal sourcebook.
You have two options for sharing your creations: keep them private for your campaigns or publish them to a public library accessible to other users (publishing requires a Hero or Master Tier subscription). Keep in mind, once content is made public, it cannot be deleted - only updated using the "Create new version" feature. DNDBeyond also handles calculations and tracks effects automatically on digital character sheets, ensuring your homebrew stays within the game’s mechanics.
"Your private homebrew content (what you create yourself) is automatically added to your Homebrew Collection, and will always be free to use with your characters and in other tools." - D&D Beyond
Homebrewery by NaturalCrit
If you’re aiming for visually polished, print-ready content, Homebrewery is the go-to choice. This free, open-source platform focuses on aesthetics, allowing creators to design documents that resemble official Fifth Edition rulebooks. It’s an excellent option for those prioritizing presentation over mechanical integration.
"The Homebrewery makes the creation and sharing of authentic looking Fifth-Edition homebrews easy. It uses Markdown with a little CSS magic to make your brews come to life." - NaturalCrit
Homebrewery features a split-pane editor: you write in Markdown on one side and see a live preview on the other. Pre-coded templates make it easy to add stat blocks, spell lists, tables, and text boxes without diving into raw HTML. Collaboration is simple, thanks to separate editing and sharing URLs. However, the platform has some specific requirements: it works best in Google Chrome for accurate PDF printing and doesn’t host images. Instead, you’ll need to upload images to external sites like Imgur and link them. Additionally, if you connect your Google Drive account, avoid deleting the "Homebrewery" folder, as the platform doesn’t maintain a project history.
| Feature | DNDBeyond Homebrew | Homebrewery |
|---|---|---|
| Primary Goal | Digital Tool Integration | Professional PDF Formatting |
| Input Method | Structured Web Forms | Markdown & CSS Editor |
| VTT Integration | Native (Maps VTT) | None (Manual Image/PDF) |
| Cost | Free (Private) / Subscription (Public) | Free (Open Source) |
| Best For | Functional character sheet mechanics | Print-ready, visually authentic documents |
Worldbuilding and Mapping Tools
Modern tools have made it easier than ever to turn scattered notes into structured campaigns and rough sketches into polished, professional maps. Let’s take a closer look at some tools that can take your worldbuilding and mapping to the next level.
Artificer DM
Artificer DM functions as a digital notebook, designed to organize your campaign's lore, NPCs, locations, and items into a searchable, wiki-style database. What sets it apart is its AI co-DM, Your Scribe, which uses your existing world details to create consistent, new content.
"When I build a city, and ask my Scribe to help me build a quest, it will use the shops, locations, and NPCs I've made. It even uses their personalities to better flesh out the quest."
– Total Modest, Discord Community Member
The platform offers core tools for free, with optional paid credits for more extensive AI assistance. Even on the basic plan, you can upload up to 10 custom objects. A standout feature is its nested mapping capability, which allows you to click on a point in your world map and seamlessly transition into detailed city or dungeon maps.
Inkarnate Map Maker
Inkarnate is a user-friendly tool for creating stunning fantasy maps through its drag-and-drop interface. With a library of over 30,000 art assets, it has powered the creation of more than 15 million maps. Whether you’re crafting a sprawling continent, a bustling city, or a tactical battle grid, Inkarnate is built for flexibility across all scales.
The Cloneable Maps feature is particularly helpful for beginners, allowing you to browse and customize maps made by other users. For those who need professional-grade visuals, Inkarnate supports high-resolution exports up to 8K, with 16K exports currently in beta for Studio plan users.
"Inkarnate remains one of my favorite tools. Not just useful, not just easy to use, but also fun. I'll legitimately make maps to wind down after a tough day."
– Alex, User
The free version includes over 1,000 assets, 2K resolution exports, and a limit of three maps. For $39.99/year, the Creator plan unlocks 30,000+ assets, 8K exports, and a 100-map limit. The Studio plan, priced at $79.99/year, offers unlimited maps, commercial use licensing, access to 16K beta exports, and additional advanced features.
Resource Packs and SRDs
Before diving into creating homebrew content, it's worth exploring the free resources available to you. These tools build on the digital platforms and generators mentioned earlier, offering legal and adaptable assets for your projects. System Reference Documents (SRDs) and open-license resource packs provide a solid foundation of rules, mechanics, and assets you can tweak and expand without worrying about copyright issues.
Open Game Systems and SRDs
A System Reference Document (SRD) serves as a collection of open-license game mechanics. It includes essential rules, character options, spells, and monsters, all designed for modification. As EN Publishing explains:
"A System Reference Document (SRD) contains the game system. It is released under an open license, making the contents of that SRD freely available to all to distribute, modify, expand, or otherwise use as they wish".
The D&D 5th Edition SRD is one of the most widely used starting points for homebrew creators. It spans over 400 pages and includes stat blocks for nearly 400 monsters - comparable to the 2014 Monster Manual. In February 2023, Wizards of the Coast released SRD 5.1 under the Creative Commons Attribution 4.0 International License, ensuring these rules remain permanently open. For those working with the 2024 rules, the 5.2 SRD - released on April 22, 2025 - offers a similar foundation tailored to the updated edition.
If you're looking for alternatives, the Pathfinder Reference Document provides a "Content Complete" option, covering nearly all first-party rules and mechanics. Another choice is the A5ESRD (Level Up), an "Advanced 5e" ruleset that maintains compatibility with the original 5e system while offering more permissive licensing terms.
It's important to note that SRDs separate Open Game Content - mechanics you are free to use - from Product Identity, which includes proprietary terms like "Beholders" or "Forgotten Realms." Before publishing your homebrew, carefully review the SRD's Product Identity list to ensure you aren't unintentionally using protected content.
In addition to SRDs, downloadable resource packs can further enhance your homebrew creations.
Downloadable Creative Commons Packs
To complement SRDs, Creative Commons resource packs provide extra visual and narrative tools for your projects. These packs often include artwork, character tokens, and map templates that you can legally integrate into your homebrew. However, understanding the specific permissions of each license is essential.
The Creative Commons Attribution (CC-BY-4.0) license is one of the most flexible options. It allows you to remix and share content as long as you credit the original creator. As EN Publishing points out:
"A Creative Commons (CC) license is more flexible than the Open Game License... It can be used to share your work, and it can be used to use and remix existing works".
When using CC resources, follow the TASL format for proper attribution: Title, Author, Source, and License.
Be cautious of ShareAlike (SA) licenses. If a resource pack includes "SA", any derivative works you create must be released under the same license, meaning your homebrew will also need to remain open-source. Additionally, Non-Commercial (NC) licenses restrict you from selling your homebrew, limiting its use to free sharing within the community.
Free vs Premium Tools Comparison
TTRPG Homebrew Tools Comparison: Free vs Premium Features and Pricing
Choosing the right tools for homebrew creation depends on understanding your project's needs. Many platforms offer a freemium model, allowing you to explore core features without an upfront cost. This makes it easier to start small and scale up when you're ready to invest.
Free Access Tools
Free tools like Donjon and Foundry VTT modules are great for getting started quickly. Donjon provides procedural generators for NPCs, dungeons, and encounters, requiring no account or setup time to deliver instant results. For mapping, Dungeon Scrawl offers a straightforward, browser-based experience focused on essential features.
However, free tools often come with limitations. Manual data entry, restricted automation, and storage caps are common drawbacks. For instance:
- Kanka's free tier supports entity-based organization for linking characters and locations but includes ads and limits on file uploads.
- Owlbear Rodeo offers 500MB of storage but lacks features like integrated character sheets or dynamic lighting.
While sufficient for basic needs, free tools can't match the efficiency and advanced capabilities of premium options.
Premium Access Tools
Premium tools elevate your workflow with features like advanced automation, AI support, and professional-quality assets. For example, Artificer DM includes a TTRPG-trained AI called "Your Scribe", which helps generate world-consistent content while keeping its core worldbuilding tools free. This aligns with the idea that premium tools enhance creativity without replacing it. As Friends & Fables put it:
"AI here isn't a replacement for your creativity, it's just here for support and speed, to help you get to the fun part faster".
Other premium tools offer even more customization and functionality:
- Inkarnate Pro provides high-resolution map exports and thousands of additional textures and stamps, available for $5/month or $25/year.
- Foundry VTT offers a $50 one-time license that includes full data ownership and powerful automation features, though professional hosting might require additional budgeting.
- Kanka's premium tiers, ranging from $4.99 to $24.99/month, remove ads and expand storage, making them ideal for larger campaigns.
| Feature | Free Tools | Premium Tools |
|---|---|---|
| Content Creation | Manual entry or basic procedural generation | AI-assisted writing and advanced templates |
| Visual Assets | Limited libraries; lower resolution exports | Full asset access; high resolution and rights |
| Organization | Basic folders or simple wiki linking | Auto-linking, nested maps, and timelines |
| User Experience | Ad-supported with community-driven support | Ad-free with priority support |
| Typical Cost | $0 | $5–$15/month or $50+ one-time fee |
Premium tools streamline workflows and provide access to features that save time and boost creativity, making them a worthwhile investment for dedicated creators.
Beginner Workflow Guide
Starting your homebrew journey can feel overwhelming, but you don’t need to master every tool right away. The trick is to follow a clear, step-by-step process that keeps you focused. Begin by identifying a gap in your system - whether it’s a rule that doesn’t quite work or a narrative element that feels underdeveloped. Then, define your idea with an elevator pitch. For example: “Like a Paladin but powered by nature spirits.” This will help you stay on track as you develop your concept. Before diving in, check community repositories like DMs Guild or Reddit to see if a similar idea already exists.
When drafting your content, refer to your system's SRD (System Reference Document) to ensure your mechanics align with established rules. Richard Bailey, a seasoned TTRPG creator, offers this advice:
"Start small, build organically, and remember: The most memorable D&D stories are born from collaboration, not control."
For your first project, keep it simple - a single house rule, monster, or spell is much more manageable than an entire campaign setting. Write your rule or idea in one to three sentences; if it takes more than that, it might be too complex for quick, in-game use. Tools like The Homebrewery or GM Binder can help you create polished PDFs, making your content easier to share and test.
Once your draft is ready, test it during 2–3 play sessions with your private group. Document any issues, especially edge cases or mechanics that feel unclear. Pay close attention to features that offer advantages like free spell slots, resource-free damage, or other mechanics that could disrupt balance.
After internal testing, take your creation to the broader community. Platforms like r/UnearthedArcana, which has over 430,000 members as of 2024, are great for gathering feedback. Use this input to refine your work, update it with version numbers, and test again. This cycle of drafting, testing, revising, and repeating is how rough ideas evolve into polished, playable content. Over time, the process becomes second nature, and each project builds your skills for the next one.
Conclusion
The world of homebrew content is massive. As of 2023, there are over 50,000 community-created products on DMs Guild and more than 10,000 tabletop RPG titles on Itch.io, offering something for every budget and level of experience. Whether you're tweaking a single rule or crafting an entire campaign setting, there’s no shortage of free and professional tools to match your needs.
The key to success is pairing your creative vision with the right resources. For smaller tweaks, the system’s SRD and a simple note-taking app might be all you need. On the other hand, tools like Inkarnate or Kanka are great for maintaining consistency in more extensive worldbuilding projects. If you’re aiming to share or even sell your creations, you'll benefit from tools that produce polished PDFs and a good grasp of licensing options like the OGL or Creative Commons.
Start small - try one or two essential tools and expand as your projects grow. The tabletop RPG community is highly supportive, and there are plenty of free resources to experiment with before committing to premium options. As Pollution from Fables.gg puts it:
"There's never been a better time to get into tabletop RPGs. You don't need to spend money to build something amazing".
Explore different workflows, listen to feedback from your players, and refine your approach. With playtesting and community input, your tools will continue to serve and elevate your creative process. Choose resources that support your imagination rather than restrict it.
FAQs
What’s the best homebrew tool to start with as a beginner?
The Homebrewery by NaturalCrit is an excellent tool for newcomers. With its straightforward interface, you can quickly craft and format custom content such as rules, monsters, or items without feeling overwhelmed.
Other beginner-friendly options include the D&D 5e Statblock Generator, which helps you create custom monster stats, and the RPG Card Creator, ideal for designing cards. Among these, The Homebrewery stands out for producing visually polished homebrew content and remains a favorite in the community.
How do I know my homebrew is balanced before I share it?
To create balanced homebrew content for D&D, start by comparing your ideas to the official material found in D&D 5e. This helps you gauge how your creation stacks up against existing content and its potential impact on gameplay. Think about its purpose and how it fits into the game - this will help you avoid making something too strong or too weak.
Once you’ve got a draft, test it during actual gameplay. Feedback from players is invaluable for spotting issues and fine-tuning your creation. Make adjustments as needed before sharing it with others to ensure it’s fun and well-balanced.
What parts of an SRD can I legally use in my homebrew?
If you’re creating homebrew content, you can incorporate Open Game Content (OGC) from a System Reference Document (SRD), but you need to stick to the rules outlined in the Open Game License (OGL). This means you must clearly identify which parts of your work are OGC and which are considered Product Identity. Additionally, you’re required to include the full SRD text as specified by the OGL. Make sure to carefully read and follow the OGL terms to ensure everything is in order.
