Anim Forge

Describe a movement in a sentence and get a real animation on your rig: Anim Forge is a Roblox Studio plugin that turns "heavy zombie lunge attack" into keyframes sitting in your place, ready to open in the Animation Editor.

This repository is the plugin. Not a sample of it, not a stripped copy — the whole client, exactly what is inside the .rbxm you download. It is public because installing a plugin file from the internet is a real thing to ask of someone, and the only honest answer to "why should I trust this?" is to hand over every line and invite you to check.

Plugin 1.6.1 (build 135) · MIT licensed · website · report a bug

Install

1. Download AnimForge.rbxm from Releases, or from https://animforge-production.up.railway.app/download.
2. Drop it in your local plugins folder:
   • Windows — %LOCALAPPDATA%\Roblox\Plugins
   • macOS — ~/Documents/Roblox/Plugins
3. Restart Studio. Anim Forge appears in the Plugins tab.

Updating is the same three steps, with the new file replacing the old one. Studio does not auto-update a plugin installed this way — that only happens for plugins installed from the Creator Store, and this one is not distributed there.

Generation needs HTTP: if the plugin says requests are disabled, turn on Game Settings → Security → Allow HTTP Requests for the place you are in.

Build it yourself

Nothing here is compiled, minified or packed — the .rbxm is these files, as they are, and Rojo is what turns one into the other:

rojo build . -o AnimForge.rbxm

Then install the file you just built instead of the one you downloaded. If you would rather trust your own build than a stranger's binary, that is the supported path, not a workaround.

Rojo's output is deterministic, so you can go further and check that the release really is this source — the releases are built with Rojo 7.7.0:

rojo build . -o mine.rbxm
sha256sum mine.rbxm AnimForge.rbxm      # certutil -hashfile <file> SHA256 on Windows

Same source and same Rojo version means the same bytes. If the two differ, something is wrong and I would like to hear about it.

What you are building:

file	what it is
src/main.server.luau	The whole dock UI — tabs, the composer, History, Settings, the first-run consent card. One long file because it is one widget.
src/api.luau	Every network call the plugin can make, and the single address it makes them to.
src/install.luau	Turns returned keyframes into a KeyframeSequence in your place (an AnimSaves folder in ServerStorage, linked from the rig), inside a ChangeHistoryService recording so Ctrl+Z undoes it.
src/descriptor.luau	Reads the selected rig into the JSON that gets sent: joint names, the exact C0/C1 offsets, part sizes.
src/settings.luau	Plugin-local settings and the random install id, stored with plugin:SetSetting — nothing leaves this machine from here.
src/icons.luau	Asset ids for the toolbar icons. Generated file.
src/version.luau	The version and build number this tree is.

What leaves your machine, and when

The plugin asks before it does anything. This is what it says on first run, word for word — src/main.server.luau, the consent card, and this README is generated from that source so the two cannot drift:

Anim Forge builds animations on its own server, using a third-party AI service, so generating sends it:

• the description you type,
• the shape of the character you pick — joint names, sizes and offsets,
• your Roblox user id, and a random id for this Studio install, so your credits stay yours,
• the animation you start from, if you pick one — its keyframes go too, so they can be edited.

Nothing else is read from your place — no scripts, no models, no other animations — and your animations stay private to you unless you publish them yourself.

Every animation costs credits. You start with free ones; more are bought in packs, either on the Anim Forge website or with Robux inside the Anim Forge experience on Roblox.

Anim Forge is installed from a file rather than through the Creator Store, so nobody vetted it for you. Its full source is public — read it before you trust it: https://github.com/Zidiam/anim-forge-plugin

Generation runs on the project's server because the model that writes the animation is far too large to run inside Studio. That is the entire reason anything leaves your machine at all.

Every request the plugin can make

All of them go to one address, compiled into src/api.luau — https://animforge-production.up.railway.app. There is no setting that changes it and no second host. Each request carries X-Roblox-User-Id, X-AF-Plugin-Build, X-AF-Plugin-Version, X-AF-Install, and nothing else identifying.

request	in the source	when
GET /v1/entitlement	api.entitlement	On opening the window, and after anything that changes your balance. Asks how many credits you have.
POST /v1/account/link/start	api.linkStart	When you move your credits to a new Studio install. Returns a one-time code to put on your Roblox profile.
POST /v1/account/link/confirm	api.linkConfirm	When you press Check afterwards. The server reads your public profile and compares.
POST /v1/redeem	api.redeem	When you paste a credit code into Settings.
POST /v1/generate	api.generate	When you press Generate, or send an edit. This is the one that carries your prompt and your rig.
GET /v1/jobs/{jobId}	api.job	Every couple of seconds while a generation is running, for progress.
POST /v1/jobs/{jobId}/cancel	api.cancel	When you cancel a running generation.
GET /v1/history?limit=50	api.history	When you open the History tab.
GET /v1/lineage/{rootId}	api.lineage	When you expand one animation to see its earlier versions.
POST /v1/jobs/{jobId}/installed	api.installed	After an animation lands in your place, so the server knows the credit was actually delivered.

What it does not do

• No remote code. No loadstring, no require by asset id, no InsertService, no LinkedSource. What you read here is all that ever runs — the plugin cannot fetch new behaviour later.
• No telemetry. No analytics service, no event pings, no crash reporting. The requests in the table above are all of them.
• It does not read your place. The rig you select is read — joints, part sizes, offsets — and nothing else. Not your scripts, not your other models, not your other animations.
• No keys, no secrets, no credentials anywhere in this tree. There is nothing here worth stealing, which is also why publishing it costs nothing.
• Your animations are yours. They install into your place and stay private to you unless you publish them yourself.

Check that yourself

grep -rn "loadstring\|getfenv\|setfenv\|InsertService\|LinkedSource" src/   # remote code
grep -rniE "api[_-]?key|secret|token|password|credential" src/               # anything key-shaped
grep -rn "HttpService" src/                                                  # every network call
grep -rn "RequestAsync" src/                                                 # ...all in api.luau

The script that builds this repo runs those same checks and refuses to write a README whose claims have stopped being true.

Credits

Generating costs credits — the server does real work per animation. You get free ones to start. After that a credit is a standard animation (a quick one costs half, the best setting costs two), edits to an animation you already made are free for the first few, and credits never expire.

More credits come from two places: packs on the website, which give you a code to paste into Settings → Redeem a code, or Robux inside the Anim Forge experience on Roblox, which land on your account automatically. The plugin itself is free and always will be.

Bugs, and everything else

Open an issue: https://github.com/Zidiam/anim-forge-plugin/issues. Include the plugin version from the Settings tab (this tree is 1.6.1, build 135) and what you typed — a prompt that produced something silly is a useful bug report.
