We auto-detect all product changes, so you don't have to click through manually

See everything your agent changed. Ship with confidence, not with hope.

See how it works

Designed for teams shipping with agents

Self-setup

No config files, no setup calls. Your agent installs FiveStack and maps every route, state, viewport, and feature flag from your code — automatically.

Hallucination-free

Rule-based verification across visual and functional changes. Same result every run, no token burn, no AI guessing about your product.

Full coverage

View all changes in interactive mode, leave comments on them - all feedback will be prepared for the agent in an agent-readable format.

From install to verified product in three steps

01

Install

Your agent handles it

One command, and FiveStack pulls context from your code and sets itself up — no configuration required.

02

Check

Every agent task, before handoff

Baseline comparison catches what changed. Deterministic where it matters, advisory where it helps.

03

Review

You decide what ships

See what's changed, previous baselines, easily pass feedback.
