Open-source & experiments

Playfleet

Open-source multi-tenant Playwright execution control plane: job queues with tenant concurrency, classified retries (so hard assertion failures don’t thrash the fleet), API keys, per-attempt artifacts, HMAC webhooks, and long-lived agent browser sessions via chromium.connect. Built as a readable TypeScript slice of production browser-automation platforms, not a CI wrapper.

CellCron

A durable, self-rescheduling HTTP job runner for celld. Supports cron expressions with IANA timezones, SQLite-backed schedules and run history, exponential retries, bearer-token API protection, and a dashboard for creating, running, and inspecting jobs without relying on in-memory timers.

A fast tree-sitter-based static analysis scanner for CI/CD pipelines with multi-language support, YAML-defined custom rules, and SARIF/JSON outputs for native GitHub and GitLab integrations. Includes CI-friendly exit codes and an optional multi-tenant dashboard server for policy management, cross-repo findings visibility, and GitHub commit status enforcement.
