Make every bug
reproducible.

Repro It finds bugs your tests miss, proves each one is real, and shrinks it into a replayable repro your team can run with one command.

How it works

Find it. Prove it. Replay it.

Repro It handles the exploration and verification. Your team gets a shareable, stable reproduction instead of a vague report or a flaky alert.

01 · FIND

Explore beyond scripted tests

scan checks reached screens. fuzz explores deeper interactions, inputs, and timing.
02 · PROVE

Keep only real failures

The finding is replayed against the same failure contract. Actions, state, environment, and evidence stay together.

03 · REPLAY

Run one command

Share the bug ID. A developer or CI runner can recreate the same failure without reconstructing the steps.

Found a checkout race: a double-submit before the cart settles. Captured the exact run. Reproduce it locally:

In your pull request

A repro you can paste, not a trace you have to decode.

One command, zero setup.

Anyone on the team runs it and watches the same failure happen, no special branch, no “works on my machine.”

Blocks the merge until it's fixed.

The repro runs in CI. It stays red while the bug lives and flips green the instant your fix holds.

The evidence travels with the bug.

Seed, inputs and state are sealed in one portable file, attached to the PR, versioned with your code.

The cloud

Production catches the bug. Your CI reproduces it.

The failures that only surface in production stop being a mystery. The cloud turns each one into the same deterministic repro you already run locally.

Security & privacy

Your code never leaves your infrastructure.

Code-blind cloud

The cloud stores derived crash signatures, replay steps, and triage state. It never receives source code, simulators, or builds.

nothing to leak

Reproduction runs in your CI

Hit Reproduce and the cloud fires a repository_dispatch into your repo. Your runners check out your code and replay the bug; only the verdict and the clip come back.

repository_dispatch

PII-safe by construction

SDKs capture structural fingerprints of inputs: length, charset, script. Never the values your users typed. No pixels, no session video, no keystrokes.

fingerprints, not values
