Open Source harness for multi-agent coding workflows
HAR is an open-source, agent-agnostic framework for building multi-agent coding workflows. Run a fleet of coding agents in parallel on any repository, with deterministic validation gates, verifiable proof, and full observability across every agent, all extensible and customizable to your own workflow and tooling.
Super interesting concept, not an obvious solution to that problem. Will need to give it a bash!

Who hunted HAR?
HAR was hunted by Karim Traiaia. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
