eBPF-powered traffic capture at the kernel level. No sidecars, no proxies, no code changes. Replay production traffic against staging to catch regressions before your users do.
Works everywhere Linux runs
You deploy with confidence, but production traffic always finds the edge cases your tests missed.
Unit tests pass. Integration tests pass. But real user traffic hits code paths you never anticipated.
You find out about regressions from angry users instead of your CI pipeline. Rollbacks are stressful and costly.
Synthetic test data can't capture the chaos of production: malformed inputs, edge cases, and unexpected combinations.
ShadowStage captures real traffic and replays it against your staging environment to catch regressions before deploy.
eBPF-powered agents capture HTTP/HTTPS traffic from production with zero code changes or performance impact.
Traffic is sanitized, compressed, and stored in S3 or MinIO. Sensitive data is automatically redacted.
Replay captured traffic against staging. Get instant diff reports showing exactly what changed.
ShadowStage uses dual capture backends that coordinate via shared eBPF maps. Plain HTTP goes through syscall tracepoints, HTTPS through TLS uprobes. No duplicates, no encrypted garbage.
Everything you need to replay traffic safely and find regressions fast.
eBPF-powered capture requires no code changes, no sidecars, no performance overhead. Just deploy the agent.
Auth headers and sensitive data are automatically stripped before replay to prevent credential leaks.
Compare responses between production and staging. Filter noise from timestamps and IDs automatically.
HTTP, HTTPS, gRPC, WebSocket, and more. Decrypt TLS traffic with automatic key extraction.
Run replays in your pipeline. Block deploys that introduce regressions. Integrate with GitHub Actions.
Track latency differences between production and staging. Catch performance regressions early.
ShadowStage agents run as a DaemonSet in your Kubernetes cluster. No code changes, no restarts, no downtime.
