JackHamr is the AI coding agent that ships software end-to-end. Instead of a single assistant that tries to do everything, it runs a team of specialist agents โ€” one writes the spec, another plans the implementation, others build, test, review, and ship the code. Each agent has its own role, tools, and personality.

Agents run on hosted cloud dev environments with VS Code, Docker, SSH access, and WireGuard-encrypted networking. Close your laptop and they keep working. Talk to them with push-to-talk voice chat or type naturally. GitHub is built in โ€” one-click clone, automatic branch-per-task, real-time commit sync, and PR creation.

Bring your own LLM keys (OpenAI, Anthropic, Google, or self-hosted) or use ours at cost โ€” swap models mid-pipeline to use the best model for each task. Build custom orchestration pipelines and agent skills. Share agents across your organization.

Pay-as-you-go with fully itemized billing โ€” infrastructure at cost, LLM tokens with zero markup. $10 free credit to start, no card required.
