Solutions . API & app backends
API backend stress testing
Find the request rate where your WAF, rate-limits and origin start to buckle, then prove a fix holds, against an environment you control.
The problem
Layer-7 load looks just like real traffic
Request floods
Realistic HTTP/2 and HTTP/3 volume exhausts threads and database connections, not bandwidth.
Test this →WAF and cache bypass
Tuned requests slip past low to mid-tier filtering and push load to the origin.
Test this →Challenge solving
Real browser clients that satisfy JavaScript challenges before flooding the origin.
Test this →The workflow
Turn an outage into a release gate
01
Reproduce the load
Replay the request pattern that pushed the API over the edge.
→02
Tune the defenses
Adjust WAF rules, rate-limits and autoscale until it holds.
→03
Block regressions
Run the chain in CI so the fix cannot silently regress.
Where do the captures come from?
It all starts in the free capture client. Record live traffic or upload a PCAP you already have, and it becomes a replayable .chain automatically.
