About

JackHamr is the AI coding agent that ships software end-to-end. Instead of a single AI assistant, it orchestrates specialist agents: a spec agent writes requirements, a planner breaks them into tasks, a builder writes code, a tester runs tests, a reviewer checks quality, and a shipper deploys. Agents run on hosted cloud dev environments with VS Code, Docker, SSH, and WireGuard-encrypted networking, so you can close your laptop and they keep working. Talk to them with push-to-talk voice chat or type naturally. GitHub is built in: 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, and swap models mid-pipeline. Pay-as-you-go with itemized billing: infrastructure at cost, LLM tokens with zero markup. $10 free credit to start, no card required.

About

OpenSpec is an open-source spec-driven development framework designed to bring structure and clarity to AI-assisted coding workflows. It introduces a lightweight specification layer that helps teams define requirements before writing code. The platform organizes each change into structured artifacts such as proposals, specifications, designs, and task lists. It integrates with over 20 AI coding tools, allowing developers to use their preferred assistants while maintaining consistency. OpenSpec emphasizes an iterative and flexible approach rather than rigid development phases. Its command-based workflow enables users to propose, implement, and archive features efficiently. Overall, OpenSpec helps developers align with AI systems, reduce ambiguity, and produce more predictable and reliable outcomes.
