host.\n\nIt is designed for people who want a local collector that can capture high-value runtime signals such as:\n\n- [x] process execs\n- [x] file operations\n- [x] TLS plaintext HTTP traffic (OpenSSL \u0026 BoringSSL)\n- [x] TCP connects\n- [x] Postgres client queries\n- [x] stdio/MCP traffic\n\n![demo](https://github.com/user-attachments/assets/e01eb6c7-bb66-4c95-be64-90161599091b)\n\n## Requirements\n\nCurrent expected runtime environment:\n\n- Linux `amd64` or `arm64` with kernel version \u003e= 5.8\n- Permissions to load eBPF programs and attach fentry/uprobe/tracepoints\n\n## Quick Start\n\nBuild:\n\n```bash\nmake build\n```\n\nRun with debug logging:\n\n```bash\nsudo ./bin/app -debug\n```\n\nRun with the terminal UI:\n\n```bash\nsudo ./bin/app -tui\n```\n\nExport events to a local JSONL file:\n\n```bash\nsudo ./bin/app -export file:///tmp/watchu.jsonl\n```\n\n## Docker Quick Start\n\nBuild the image:\n\n```bash\ndocker buildx build -t watchu -f Dockerfile --load .\n```\n\nRun it:\n\n```bash\ndocker run --rm \\\n  --cap-add=CAP_SYS_ADMIN \\\n  --cap-add=CAP_SYS_PTRACE \\\n  --cap-add=CAP_BPF \\\n  --cap-add=CAP_PERFMON \\\n  -v /sys/kernel/debug:/sys/kernel/debug:ro \\\n  --pid=host \\\n  --security-opt apparmor=unconfined \\\n  watchu\n```\n\n## Development\n\nCheck the [CONTRIBUTING.md](./CONTRIBUTING.md) guide.\n\n\n[ci-check-badge]: https://github.com/tensorchord/watchu-cli/actions/workflows/build.yml/badge.svg\n[ci-check-file]:
