While you sleep, your code gets better.

NightWatch is an autonomous AI developer that reviews pull requests, writes tests, catches bugs, and ships improvements — every night, without being asked.

What it does

Built for the solo developer
who wants a team.

Reviews every PR

Reads your code, understands context, flags bugs before they land. Not surface-level lint — real architectural feedback.

Catches what humans miss

Writes tests autonomously

For every PR: unit tests, integration tests, edge cases. Writes them, runs them, reports back before you wake up.

Never ship untested code again

Detects vulnerabilities

Security audit on every change. OWASP checks, dependency vulnerabilities, authentication flaws — caught before production.

Security while you rest

Runs 24/7, reports at 7am

Morning standup report: what changed, what was reviewed, what needs your attention. You decide what to merge.

Your daily code briefing

Setup in minutes

Three steps to never review code manually again.

01

Connect your GitHub repo

One-click GitHub OAuth. NightWatch reads your repo structure, understands your stack, and learns your patterns.

02

Define your rules once

Style guide, test expectations, security policy. NightWatch respects your standards — no generic feedback.

03

Wake up to shipped code

Every night, NightWatch reviews open PRs, writes tests, fixes bugs. You review the output, hit merge, ship faster.

The loop

Your review queue, cleaned every night.

Evening
You open a PR, merge to main, go to sleep
22:00 – 06:00
NightWatch works: reviews code, writes tests, flags bugs, opens its own fix PRs
07:00
Morning report in your inbox: 3 PRs reviewed, 47 tests added, 2 bugs caught, 1 security fix merged
09:00
You hit merge on the fix PRs, ship to production. Code better than when you left it.

The difference

Not a chatbot. Not a copilot.
A teammate that works nights.
