Works 24/7

No standup meetings. No context switching. Your agent starts when you describe what you need and reports back when it's done.

Owns the loop

Research, implementation, tests, documentation — one agent handles the full stack. You review, approve, ship.

Reports back

Every PR includes a summary of what changed, why, and what to watch for. Your agent keeps you informed without interrupting your flow.

What it does

Built for developers who want leverage.

01

Feature Implementation

Describe a feature in plain English. Folio reads the codebase, writes the implementation, handles edge cases, and opens a PR.

02

Test Coverage

Every change comes with tests — unit, integration, and edge cases. Folio writes them as it goes, not as an afterthought.

03

Refactor & Improve

Tell Folio to clean up a module, reduce latency, or modernize a legacy section. It touches only what you asked it to touch.

04

Bug Investigation

Paste a stack trace. Folio reproduces the bug, identifies the root cause, writes a fix, and adds a regression test.

What you get

Every task = one done thing.

Folio doesn't do homework. It ships production-ready code that you can merge, review, or hand off. Each task is atomic, tracked, and reported.

Your next engineer doesn't need a desk.

Software teams spend half their time doing what a machine could do faster. Folio exists to close that gap — permanently. One agent, running all the time, building everything you need, reporting to you when it's done.
