Bring your own AI · for Roblox developers
Bring the Claude Code, Codex or Cursor account you already use. Baseplate connects it to your game files and Roblox Studio, so you can build, review and playtest in one place. Review requests to restructure your build and undo supported edits. No extra AI credits from Baseplate; your provider’s usage limits still apply.

This interactive simulation runs entirely in your browser — no account, AI credits or source upload. Type a Roblox task and watch Baseplate coordinate the builder, Studio and Regression Lab.

The flagship loop
Every Roblox dev knows the ritual: playtest, squint at the Output window, alt-tab, guess, repeat. Baseplate's bridge gives agents eyes inside Studio — they run the playtest, read the actual runtime error, fix the cause in your source, and re-run until the console is clean.
The agent runs your game through the live Studio bridge and watches the console — the same output you'd read, minus the squinting.
It reads the real stack trace, finds the cause in your Luau source, and explains it in plain language — not a cryptic dump.
It edits src/ directly. Rojo syncs the change into Studio the moment it's written.
It playtests again and only reports PASS when the console is actually clean. No "should work now".
Exploit Guard
If your server trusts the client — prices, rewards, damage — someone will find it. Exploit Guard audits your live game like an attacker would: it maps every remote, tells you each hole as a plain-language attack story ranked by severity, and writes the server-side hardening for you.
Included free Exploit Guard ships in the Free plan. Protecting your revenue shouldn't be a paywall.
The full toolbelt
Each of these is a one-click mission that runs on a real agent with eyes inside your game — not a chatbot guessing from the outside.
A Foreman plans the mission and spawns builders in their own tiles, each owning its files. Watch a whole feature get built in parallel, narrated in a live mission feed.
"Is it safe to release?" answered honestly: one verdict across runtime, security, data safety and robustness — with every blocker named as its real-world consequence.
Models every currency source and sink in your game, simulates a cohort of players, and flags inflation, progression walls and money-printer loops — with tuned numbers.
Connects to your published game via Open Cloud, reads real player data, and diagnoses retention cliffs, stuck players, corrupted saves and live exploits.
Describe a game in one sentence. Baseplate scaffolds the workspace and a Crew builds the first playable slice — loop, saving, UI — with a first version you can review and playtest.
Pick your genre — tycoon, simulator, obby, tower defense, horror escape, battlegrounds. Baseplate scaffolds the project and agents build the real loop into it. Free plan included.
Generates mobile-safe Roblox UI in Luau, then looks at the result through the bridge — overlap, off-screen, contrast — and iterates until the layout is clean.
A knowledge index of your source — ask "where is the shop logic?" and get file:line answers instead of an agent burning tokens re-reading every script.
Battle-tested, one-click missions: gacha with pity, anti-dupe trading, daily streaks, rebirth, global leaderboards. The systems every hit game needs, pre-briefed.
Simulated player load hunting the bugs only multiplayer surfaces: desyncs, two-players-buy-the-last-item races, client-authority holes, state leaks.
The deck
Agents live in tiles on a deck — real terminals when you want them, clean transcripts when you don't. A Kanban board dispatches work, a mission feed narrates progress, and the Studio panel shows your bridge, Rojo and plugin health at a glance.

The app and Studio bridge run locally. Project data goes only to the AI provider you choose; Baseplate does not host your source repository.
Prerequisites: Roblox Studio plus at least one supported agent CLI with working sign-in. Claude Code, Codex and Cursor support Playtest Copilot; Cursor requires Cursor Agent CLI in addition to any IDE installation. Grok supports builder tiles. Antigravity supports Native tiles for personal Google accounts; Gemini CLI requires an API key or a supported organization license. Windows downloads use Microsoft Store; unsigned direct installers may show SmartScreen. The current unsigned macOS build requires Apple's Open Anyway steps; only an Apple-notarized release can remove that warning.
FAQ
You need a supported agent CLI account. Claude Code, Codex and Cursor support Playtest Copilot. Grok supports builder tiles; Antigravity supports Native tiles for personal Google accounts. Gemini CLI requires an API key or a supported organization license. Baseplate does not include AI inference. Free costs $0, Pro costs $4.99/month, and your provider’s usage limits and charges still apply.
Baseplate does not upload your projects or keys to Baseplate. Your selected AI provider receives prompts, code and context needed for the work. License validation sends your key and a random installation identifier to our Cloudflare service. If you enable team collaboration, board cards, shared prompts and display names sync through the team service; source files and API keys do not.
Assistant can write code and playtest inside Studio. Roblox also provides a built-in MCP server for external AI clients. Baseplate adds a desktop workspace with agent tiles, Rojo project files, a task board and reusable regression recipes. Try the built-in tools first if they already cover your workflow.
A terminal agent can already connect to Roblox’s official Studio MCP server. Baseplate brings the workflow together: project setup, visible agent activity, a task board, Studio change history and production labs. A bridge alone is not a unique Baseplate feature.
Anytime, yourself — no email required. Open the billing portal and sign in with the email you paid with; from there you can cancel, switch between Pro and Studio, update your card, or download invoices. A cancellation keeps your plan active until the end of the period you've already paid for, then drops you to Free. If the portal link isn't working yet, email support@baseplatedev.com and we'll sort it out.
You drop back to Free — one agent at a time, with the bridge, Regression Lab and Remote Contract Compiler still included. Your projects, workspaces and history stay untouched on your disk.
The plugin only talks to Baseplate on 127.0.0.1. The local server rejects foreign Host and browser Origin values, the Electron renderer is sandboxed, and release packages use ASAR integrity checks. No security control can guarantee invulnerability, so review agent-generated changes before you ship.
Free is the full core loop: one agent with complete Studio access, Playtest Copilot, Rojo sync, Regression Lab and Remote Contract Compiler. It's deliberately generous — if Baseplate never earns your upgrade, it should still make your game better.
