PlatformBuild in the Browser
Build in the browser.
Everything you need to build is in the browser: the editor, the build agent, a live preview, the database, a terminal, and the running app itself. Nothing to install. It runs on the same platform that serves production, so what you build behaves the same way once it’s live.
A live preview. The app runs inside the environment and reloads the moment you change the code or the spec, on its own development data.
See every move the agent makes.
The Agents tab keeps a running record of everything Remy does as it builds: files read and written, commands run, and the specialist agents it calls in, like the design agent shown here.
Test flows in a live browser.
The QA agent drives a full Chrome browser through multi-step flows, signing in as any role and clicking through the app the way a person would.
Plan first, then code.
Before a substantial change, the agent lays out what it intends to do in plain language and waits for you to approve or reject it.
Choose the model Remy builds with.
Point the build agent at Claude, GPT, Gemini, or another frontier model, and switch whenever you like.
Synthetic data to test against.
Scenarios seed the database with realistic sample data in a known state. Load one in a click and view the app as any role.
Browse and edit the database.
Every app gets a managed SQL database, with its tables and rows readable and editable as you build.
Edit the code by hand.
Every app is TypeScript and React you own outright, with a full editor and file tree whenever you want to work directly.
Search and replace, project-wide.
Find and rewrite anything across the entire codebase from the editor.
Full terminal access.
A shell inside the environment for running commands, installing packages, and using git.
Watch the logs stream.
Every backend run is logged with its inputs, outputs, and errors, streaming live so you can see what the app is doing.
Debug any backend method.
Run any backend function on its own, feed it the inputs you choose, and inspect exactly what it returns.
What it costs, itemized.
Every model call and action is metered at cost and charted by tokens and spend, so the price of building stays visible.
Plain-language spec, in sync with the code.
Every app is defined by a readable spec of what it does, who uses it, and the data it holds.
Design authored in the spec.
Fonts, type, and color are set in the spec as brand guidelines and shown with live samples, written down rather than buried in code.
Human on one layer, machine on the other.
The spec’s source is plain prose with inline annotations: readable for people, precise enough for Remy to compile into working software.
Your machine, if you prefer.
Every Remy app is a git repository. Clone it and run the identical environment locally over a secure tunnel: the same pipeline, the same database, the same SDK, in your own editor.
git clone https://git.mscdn.ai/your-app.git cd your-app mindstudio-local --port 5173
