Agentic app builder

Describe the product. Build the working app.

ReformCode turns a product idea into a multi-file application with an agent team, live preview, reviewable changes, and an iteration loop that stays in one workspace.

One continuous loop

Prompt. Build. Preview. Keep going.

Start from an idea or import an existing repository. The same agent workspace handles creation, iteration, review, and the evidence needed before release.

01

Plan the product

The architect turns your prompt into routes, components, data boundaries, and a reviewable implementation plan.

02

Build across files

The coding agent reads the workspace, stages multi-file changes, and loops through review, security, and test-generation specialists.

03

Preview and improve

Review the diff, apply it, inspect the live preview, then keep prompting until the product is ready for your release workflow.

Built-in engineering judgment

The agent writes. You stay in control.

Every generation is staged as a proposal. You can inspect changed files, approve architecture, reject destructive edits, and continue prompting from the current workspace instead of starting over.

Automatic review and security pass
API, database, and test scaffolding
Persistent projects and conversations
GitHub export and release evidence

Proof remains honest

Generated tests are labeled generated until they run, without presenting unexecuted checks as proof. Runtime execution is not part of the public repository check; builds and deploys stay planned until an isolated runtime records the result.

Existing app?

Import a public GitHub repository, map the code and risks, then hand the prioritized work into the same builder.

What should we build?

Give the agent the audience, core workflow, visual direction, and any constraints you already know.
