How it works

Three moves, zero surprises.

Drop one middleware line in, forget about it, and read a clean dashboard when something shows up. Hover any card for plain English — tap it for the short version.

1

Scan

Edge-safe pattern matching runs on every request — URL, headers, body. 13 rules across 4 scanners. Sub-5ms overhead.

2

Capture

Findings stream to Watchman via fire-and-forget telemetry. Network failures never delay your app's response.

3

Review

Filterable dashboard with commit, branch, and environment context. Severity triage, suppression rules, per-session drill-down.

Our mission

Every subscription feeds a child.

One hundred percent of Watchman revenue funds the Kai'Ros International orphanage in Kumasi, Ghana. Every scan you run, every threat we catch for you, every dollar you pay — it becomes a meal, a school book, a bed, a future for a child who would not otherwise have one.

We build software for a living so that children can live.

“Son of man, I have made thee a watchman unto the house of Israel.”
