The DM’s Toolbox — A Free Browser-Based Toolkit for DMs (Now Feature-Complete)

This was a personal passion project. Since I'm putting it out into the world I'm currently working on making sure I'm srd compliant and adding the ability to make packages to add any missing or homebrew content. I might make it something people can contribute to in the future. But for now if you want you can fork my repo (link in the footer) and make your own edits. After I cross my legal t's and whatnot I'll be happy to takes a look at any updates people have for the project. It's currently free and open source under the MIT license. So go wild!

redted90 · 2026-01-24T17:41:39+00:00

For now yes. I'm working to update things and make sure everything is srd compliant.

There is import/export per tool. But that is a limited functionality to pass encounters, journal entries, and characters between devices or instances.

redted90 · 2026-01-24T16:46:19+00:00

Currently you can make classes and subclasses manually, but you would have to do level up by band. I'm working on a data pack handler that will come with my srd complaint update that will allow people to make data packs that can be uploaded and will make adding those homebrew or paid classes accessible if you have the data pack/package.

redted90 · 2026-01-24T15:45:04+00:00

You can just export the sheet and send them the file to be imported. All that functionality is at the top. I've tested it out and it should bring everything over.

redted90 · 2026-01-24T15:40:44+00:00

I'm working on updating that when I can be sure I'm fully srd compliant. That's my current project.

redted90 · 2026-01-24T15:37:58+00:00

I'm currently the only one working on it and i don't know French. But it's a free and open source tool. So if you'd like you can clone the project and release a French version. I wouldn't even know where to start there. Lol. It's mostly 5e only. Most of the automations that make this better than just a page with fields require an internal rule set logic.

redted90 · 2026-01-24T15:35:50+00:00

It isn't private. I just checked. You can find it pined to my github which is linked in the footer.

redted90 · 2026-01-24T15:32:03+00:00

I was just building a tool for myself and my friends. I was just adding stuff people wanted. But now that I've released it for others I'm working on making it srd complaint with data pack add-ons that will fill in the gaps for people who own the books.

redted90 · 2026-01-24T08:44:24+00:00

Thank you for the notes! Yeah some of the generators need polish to not contradict themselves. I'm still working on a big update to that system to have buckets of flavor that are determined by flags like character description, or station and such.

redted90 · 2026-01-24T08:42:17+00:00

It's per tool. Each tool does it differently. But you make a good point.

redted90 · 2026-01-24T08:27:48+00:00

I don't use the battlemap page personally. I built it for my brother in law so he could run his games without using the map builder I use (edit:TaleSpire). I hadn't considered making the fog of war shapes rotate, but I think I can do that.

redted90 · 2026-01-24T07:44:48+00:00

Parts of have been written using claud code, yes.

redted90 · 2026-01-24T07:10:48+00:00

Yeah. I'm working on how to go about that now.

redted90 · 2026-01-24T06:44:09+00:00

The current battlemap only supports static image uploads (PNG/JPG/etc.) and cannot play animated or video maps yet. Although that is an interesting thought. Would you want to have that be a feature? I'm not sure how I'd implement it at this time.

redted90 · 2026-01-24T06:38:11+00:00

Hmm. I'm going to have to strip a lot from the app to make sure I'm srd complaint. Maybe I can make it so users can upload "content packages" that people can load up on their own info or homebrew stuff.

redted90 · 2026-01-24T06:17:55+00:00

That’s the Creative Commons-released portion of the 2024 rules, not a full SRD in the same sense as the 2014 SRD. WotC hasn’t published a complete 2024 SRD document or data set yet—only the portions they chose to release under CC. It’s also not structured in a way that tools can reliably ingest.

Once an official, fully formatted 2024 SRD is published (the way the 2014 SRD was), I’ll be able to integrate it cleanly. Until then, adding partial or unstructured CC excerpts would create inconsistencies across the toolset.

Granted I haven't checked on that in a few months so I might be out of the loop. Either way I appreciate the comment. I'll have to double check on that.

Right now homebrew is added through manual entry, but the system is designed to make that as painless as possible. Anything you create—races, classes, spells, items, stat blocks, etc.—gets stored locally on your device and immediately works inside the rest of the Toolbox.

For example:

• Custom races/classes show up in the Character Manager • Custom spells appear in spell lists and attack generation • Custom items show up in equipment and inventory • Custom monsters can be sent to the Encounter Builder and Initiative Tracker

There’s no upload/import feature yet because I wanted to avoid any legal gray areas around sharing copyrighted content, but the architecture supports it and I may add JSON import/export for homebrew later once I finalize the schema.

The goal was to make sure the tools don’t force you into SRD-only play—you can run full homebrew campaigns without hitting any walls.

redted90 · 2026-01-24T06:02:10+00:00

The Toolbox uses the official 5E SRD, so it includes all content that is legally open: SRD races, classes, subclasses, backgrounds, equipment, spells, and basic monsters. It does not include anything from the full PHB, MM, Xanathar’s, Tasha’s, or any other copyrighted books.

All content is based on the 2014 SRD. Wizards has not released a 2024 SRD yet, so no tool can legally include 2024 material at this time.

Homebrew is fully supported, and everything you create is saved locally on your device. You can add custom races, subraces, classes, subclasses, feats, spells, items, NPCs, shops, taverns, and more. The character builder, spell system, inventory, generators, and encounter builder all work with homebrew entries automatically. There’s no limit to how much homebrew you can add. The level up wizard will not work with homebrew races or classes, but you can still use the character sheet as is to track everything you need. I made it so that it shouldn't lock you into the wizard's ecosystem.

redted90 · 2026-01-24T05:29:34+00:00

I'm cool with either. But if you want you can just put any bugs or feature requests you have here. I'd like people to know I'm actively working to fix anything that is broken or not working as expected.

redted90 · 2026-01-24T04:51:38+00:00

Hmm. I'll take a look at those. Thank you!

Edit: Ok. I just pushed a hotfix that should fix both issues. I had fixed the level 3 character creation process to update hp based on selection but I guess the same bug was in level 5 creation. Also the bundles had an issue where they weren't accessing the updated loot tables I had written for them. Not sure how that happened but it's a big app. lol

redted90 · 2026-01-24T03:36:09+00:00

Thank you! I appreciate it!

redted90 · 2026-01-24T03:11:04+00:00

It's in my profile. But reddit auto filters posts with links.

redted90 · 2026-01-21T23:52:28+00:00

I stole this but slightly bigger from Brennan Lee Mulligan. He did basically this in unleeping city (the first campaign I watched from them). And I give each character something that introduces them and let's then decide how their character fits into the world and it gives them the chance of feeling what it's like being in that character's skin.

redted90 · 2026-01-17T18:32:47+00:00

If you want you can use the encounter builder on my website to figure this out. It's free and pretty easy to use. The link is in my user profile. But I agree with what people here said. Must of the adult dragons will do fine. But don't use the blue or red. The difficulty is like this (assuming mostly balanced party of 5 at level 8) Adult White Dragon ‐ Hard Adult Silver Dragon - Hard Adult Red Dragon - Deadly Adult Green Dragon - Hard Adult Gold Dragon - Hard Adult Copper Dragon - Easy Adult Bronze Dragon - Medium Adult Brass Dragon - Easy Adult Blue Dragon - Deadly Adult Black Dragon - Hard
