Tablekeeper is an autonomous software engineering project built for the Dark Factory Hackathon by WeAreDevelopers and BAND. Under strict dark factory rules, zero lines of application code were written by humans. Our team acted solely as factory builders, defining generic mandates and orchestrating three autonomous AI agent seats inside BAND Desktop: Coordinator, Developer, and Reviewer. The Coordinator parsed the official track specification into structured work items, managed room handoffs, and maintained strict stage isolation. The Developer autonomously implemented the complete Stage 1 REST JSON API service, resolving complex domain requirements such as concurrency locking to prevent double-booking, safe idempotent write replays, atomic reservation transactions, state export and import, and IANA timezone daylight-saving transitions. The Reviewer independently inspected commits and verified test runs. The completed backend was verified in an isolated container environment against the official hackathon test harness, achieving a clean pass across all 120 test cases. The project repository includes generic mandate files passing the swap test, the complete room.json collaboration log, and container deployment files.

🌎 Hybrid Hackathon | 💻 Online Build: 3–8 November 2026 | On-site Phase: 8 November 2026 📍 On-site Venue: Pierpont Place 163 W Pierpont Ave, Salt Lake City, UT 84101, USA ✨ Please note that travel and accommodation are not covered.

🌎 Online Hackathon | 💻 Online Build: Sept 26 - Oct 5, 2026 A virtual, global hackathon. Build from anywhere in the world. Dark Factory is the official hackathon of WeAreDevelopers World Congress North America, presented by BAND, but you don't need to be in San Jose to take part. For one week, you build a software factory in BAND Desktop: a band of coding agents that plans work, implements it and checks its own results. 🎟️ Bonus for sign-ups: you are eligible for a free ticket to WeAreDevelopers World Congress North America in San Jose (Sep 23–25). If you do go, stop by the BAND booth: a surprise is waiting for you.
