You're using LaunchDarkly to control risk. Add Koalr to measure it.
Every PR that touches a feature flag now gets a risk score.
LaunchDarkly gives you the kill switch. Koalr tells you which PRs are likely to need it — before they ship. Connect your flag catalog to deploy risk scoring and see exactly how flag rollouts affect your incident rate.
Risk scoring that understands feature flags
Most deploy risk tools treat a PR as a diff. Koalr understands that a diff touching a flag key carries a fundamentally different risk profile than one that doesn't.
Flag change detection
Koalr statically analyzes every PR and detects files that reference feature flag keys, SDK calls, or flag-gating patterns. No manual tagging required — it works on your existing codebase from day one.
0–100 risk score per PR
Each PR that touches a feature flag gets a composite risk score with the top contributing signals broken out: blast radius, flag age, author familiarity with the flag surface, change entropy, and historical incident correlation.
DORA metrics connected
Flag rollouts and kill-switch events are correlated with your DORA dashboard. See exactly how flag-gated deploys affect your deployment frequency, change failure rate, and MTTR over time.
What Koalr adds to your LaunchDarkly workflow
LaunchDarkly already gives you runtime control. Koalr adds pre-merge visibility — so your team knows the risk profile of a flag change before it ever reaches production, not after an incident starts.
- Detects which PRs add, remove, or modify feature flag references across your entire codebase
- Scores the blast radius: how many users, segments, or services could be affected by this flag change
- Alerts on PRs where flag toggles ship alongside breaking API changes or DDL migrations
- Connects flag kill-switch events to MTTR in your DORA dashboard — see how quickly your team recovers
- Shows which flags have the highest historical correlation with production incidents
- Tracks flag staleness: flags that haven’t been cleaned up increase risk surface area over time
Kill-switch events automatically correlated with incident close time in your DORA dashboard.
Connect in 30 minutes — free trial, no credit card
Three steps from signup to your first flag risk score. No professional services, no implementation project.
Install the Koalr GitHub App on your organization. Koalr begins backfilling 90 days of PR history and immediately starts detecting flag references in merged code.
Authorize Koalr via the LaunchDarkly API. Koalr reads your flag definitions, targeting rules, and recent variation history. No write access is required.
When your next PR opens, Koalr calculates the risk score accounting for flag changes and posts it as a GitHub Check. The score appears inline in the PR — no dashboard visit needed.
Why flag changes deserve their own risk signal
Flags expand blast radius silently
A three-line PR that flips a flag from 5% to 100% rollout has a fundamentally different risk profile than a three-line refactor. Standard code diff analysis misses this entirely. Koalr detects it.
Kill switches reduce MTTR — but only if you ship safely
LaunchDarkly’s instant kill switch is your recovery path. Koalr’s pre-merge risk score is your prevention layer. Together they close the gap between deployment confidence and production stability.
Flag debt accumulates silently
Flags that outlive their intended lifespan become landmines. Koalr tracks flag age, reference count, and modification history — surfacing which flags are adding systemic risk to your codebase.
Incidents cluster around flag changes
Post-incident reviews consistently find flag toggles at the root. Koalr builds that correlation into your risk model from historical data — so the next high-risk flag change gets flagged before it causes an incident.
