OnePatch

OnePatch is an AI on call tool for engineering teams that ship code quickly, often through coding agents. It instruments a team's stack, checks each pull request against live production telemetry to confirm the change behaves correctly after deploy, and works to fix what breaks. The vendor frames the problem as teams shipping dozens of pull requests a day while failures take hours to locate across logs, traces, dashboards and chat. The product interface includes views for pull requests, monitors, dashboards, incidents and investigation threads. It fills gaps in observability by adding instrumentation proactively, so a change does not reach production with blind spots, and it investigates alerts that would otherwise be buried among noise. The goal is to replace the manual work of stitching signals together during an incident. The company is backed by Y Combinator, has a sign in for existing users, and provides documentation and an install page. Pricing is based on conclusive investigations. Starter is $500 per month and includes 25 conclusive investigations, with each additional investigation costing $20. Scale is $2,000 per month and includes 100 conclusive investigations, with additional ones at $10 each. An enterprise tier, quoted on request, adds investigation discounts and a dedicated success engineer.
