How it works
From webhook to reviewed, in one quiet pass.
01
Connect your provider
Authorise GitHub or Azure DevOps with least-privilege scopes. Work/school Entra accounts use OAuth; personal accounts connect with a Personal Access Token.
02
Every PR becomes a signal
Changed files and patch metadata are analysed asynchronously into a risk grade, reviewer guidance, missing-test and security findings, and a concise summary.
03
Route it to the right people
A tidy review comment lands on the PR, and high-risk alerts reach Teams, Slack, or the dashboard before the change slips through.
What you get
Precise where it counts. Quiet everywhere else.
Risk classification
Know which PRs actually need a senior reviewer.
High, medium, and low grades are derived from file paths, diff size, review heuristics, and provider context — so triage takes seconds, not a standup.
PR #247 · auth/login.ts, auth/session.tsHIGH
Authentication paths changed · token & identity handling · +142 / −38
Reviewer focus: token expiry and session invalidation. Start with auth/session.ts.
Diff retention
Patch data never touches disk.
0
bytes of diff stored permanently
Patches are analysed in memory, secret-redacted, then discarded. Only the risk signal is kept.
Release notes
Completion notes for every audience.
TechnicalBusiness
● #247 auth — high · token expiry paths

Privacy by design
No diff retention
Patch content lives in memory during analysis only. Nothing is written to permanent storage.
Secret redaction
Pattern and entropy checks scrub API keys, tokens, and connection strings before analysis begins.
Human in the loop
Every recommendation is advisory. Northstar surfaces the risk — your team makes the call.
Minimal permissions
OAuth scopes stay narrow, sign-in supports GitHub and Microsoft, and reconnect stays explicit and revocable.
Simple, predictable pricing
One flat price. No per-seat math.
Most review tools bill for every developer, so the invoice climbs each time you hire. We charge one clear monthly price for a generous pool of pull-request analyses that your whole team shares. Grow the team without growing the bill — priced by the work you ship, not the people you employ.
Priced on your code, not your headcount
Add as many engineers as you like. Your plan scales with pull-request volume — never with seat counts or per-user fees.
No surprises on the invoice
A single flat rate with a clear analysis allowance. No background usage meters, no overage shocks, no seat audits at renewal.
Higher tiers, honestly better value
Move up for unlimited repositories, a much larger analysis pool, advanced risk analytics, release notes, and audit logs — what growing teams genuinely need.
