Precision-built evaluation for competitive coding.
exec-d is a Codeforces-style judge that compiles once, executes per testcase, and reports verdicts you can trust. Built with Next.js, Express, BullMQ, and a hardened Docker runtime.
Architecture that stays legible under load.
Every submission is queued, executed inside a locked-down container, and reconciled with per-testcase results. No noise, no ambiguity—just deterministic outcomes.
Compile once, execute per testcase, and capture definitive outcomes.
No network, strict CPU limits, and hardened containers by default.
BullMQ orchestration keeps spikes predictable and observable.
A clean lifecycle that surfaces the exact verdict state.
Track queue depth, worker health, and execution timings.
Isolation-first defaults to keep untrusted code contained.
Start validating submissions with confidence.
Keep the judge predictable for participants and effortless for maintainers.
