Open Agent Hackathon 2026

GenAI.Works

Cleanest fit on the board: fully online, free, solo-allowed (teams of 1–5), and explicitly model-agnostic — closed models and paid APIs are permitted, so build the agent on the Claude API. Real cash and a tight 6-day sprint that rewards your ship-fast style. Only catch: the strongest tracks lean on sponsor tech (NVIDIA/Zetaris), so read the track rules before picking one.

AssemblyAI Voice Agent Hackathon

AssemblyAI × lablab.ai

Real cash, fully online, and you can still use the Claude API as the agent's brain while AssemblyAI handles the voice layer. Biggest catch: it closes 30 Sep — only a few days out — so jump only if you can ship a voice-agent demo fast, and you must build on AssemblyAI.

AMD Developer Hackathon: ACT III

AMD × lablab.ai

Online build phase, free, with cash on the table — but it's built around AMD GPUs/ROCm infrastructure, off your Claude-API + web edge. Worth it only if you want to stretch into GPU/infra work; otherwise it's a weaker use of a sprint.

WeAreDevelopers × BAND: Dark Factory

WeAreDevelopers × BAND

Fully virtual and on-theme (a 'band' of coding agents that plan, build and self-check), solo-doable. The catch: you must build inside BAND Desktop (their platform), not your own stack, and prize/entry details aren't posted — verify on site before committing.

Vultr: Agent Rush Hackathon

Vultr × lablab.ai

AI-agents theme fits you and there's an online build phase, but it's hybrid with an on-site finale (8 Nov) and expects agents 'sandboxed on Vultr' infra; prize pool and entry cost aren't posted. Tentative until you confirm an online-only path on site.

Health-a-thon 2026

Reskilll

India-based, online and free — point your Claude-API skills at real health problems (cancer, diabetes, maternal health). Two catches: it's framed as doctors + technologists co-creating (you may need a clinical partner), and registration closes ~28 Sep, so it's now-or-never. Details are thin — confirm on site.
