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.

What's the story behind your product?

JIterator's answer

In 2015, to address the increasingly severe challenges of automated testing for Taobao's price calculation system, we developed a traffic testing tool suitable for Taobao's backend systems, inspired by Tcpcopy. With its help, the price calculation system has never had a failure since.

In 2016, we were tasked to support the largest reconstruction project in the history of Alibaba's transaction system: the middleware transformation project. To support core transactions, we improved the product and achieved fully automated Mock capabilities for downstream systems, ensuring the smooth implementation of the project. Later, recording and replay became the core safeguard for the transaction system.

As our reputation spread within the group, our product was adopted and used by more teams. By 2023, more than 7,000 systems had adopted the system for support and it had also supported hundreds of system reconstruction projects, including Ping An Bank externally.

Due to organizational strategy adjustments, the traffic testing tool no longer provides external services. We created JIterator to provide services to the public. It has also surpassed the original traffic testing tool in many aspects, surpassing its predecessor.

Which are the primary technologies used for building your product?

JIterator's answer

Traffic recording and playback technology based on JVM-TI

Who are some of the biggest customers of your product?

JIterator's answer

Alibaba Pingan bank
