Show HN: Haystack – Review the PRs that need human attention Hey HN! We're building Haystack ( https://ift.tt/SWi6AKL ) to help teams deal with the explosion in the number of pull requests that need to be reviewed due to the rise of coding agents. Haystack replaces the GitHub PR review system with a queue that triages each PR before a human has to read any diffs. It looks at the diffs, the codebase, and the coding-agent conversation that produced the PR. Haystack then routes it into one of three buckets: 1. Safe to merge. This means the PR has enough evidence behind it that the team can merge it without another human's review. Some examples: -- A small UI copy change that includes a screenshot showing the final state -- A backend change where the author clearly tested the important paths and ran the changes in a real environment 2. Needs fixes. This means that the PR has bugs or violates a rule in your codebase and therefore the PR needs to be fixed by the author. Some examples...

Show HN: Cubic Doggo, a Open-Source 12-DOF 4-Legged Robot Based on ROS2 This is a recipe for building intermediate-priced robot dog from scratch with all commercial/3D-printed parts, controlled by Rasp Pi 5 and ROS2 Jazzy. A manually coded walk gait is implemented so far, which can be controlled by a controller to move forward or change directions. It does not yet have an IMU required for RL training; however, I believe it's one of the simplest design out there available for multiple development paths. https://ift.tt/OjcpT8K May 19, 2026 at 12:20AM

Show HN: InsForge – Open-source Heroku for coding agents Hi HN, I'm Hang, cofounder of InsForge (YC P26). InsForge is an open-source Heroku for AI coding agents: a backend platform designed for coding agents to deploy, operate, and debug end-to-end. Open source under Apache 2.0 ( https://ift.tt/Ncnmat6 ). Quick demo here ( https://youtu.be/7Bax5qz0IfM ). We started InsForge because we just wanted our Claude Code to handle all the backend / infra stuff for us, instead of us jumping between dashboards doing manual config, or copy paste logs and docs back to agents. We first tried creating a folder with bunch of .MD files, and installing MCPs like Supabase, Vercel, GitHub, Context7. But soon we found MCPs have their own problems: (a) Tools get pre-loaded into context, before agents even do anything (b) bad design, payloads are returning 10k+ tokens, and (c) a lot of stuff still can’t be done by MCP: e.g. telemetry and configs. So we think, because coding agents are so good at CLI, why...
