New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

Redesigning source control at Anthropic

As our merges per day grew more than tenfold, source control became our biggest development bottleneck. Here, we share how we migrated to an in-house version control system in five months.

Giving away a free app audit every day! I’m new here, so this is my way of getting to know you and giving something back. Every day I’ll roast an app: onboarding + paywall, where the magic (money) happens. 💸 Drop your App Store link below and I’ll tell you what I’d fix first.

On August 17, GitHub experienced a significant outage that disrupted developers and organizations around the world. If you were trying to ship software that day, we let you down. I posted in March and April about the steps we’re taking to make GitHub more reliable. The work is still underway. Here is an update: github.blog/news-insights/co…

The August 17 outage, and the work ahead

London has OFFICIALLY overtaken Paris to become Europe's leading tech hub! 🇬🇧 @dealroomco has just released its latest Tech Ecosystem Index, where it ranks tech hubs based on its growth, scale and density. Last year Paris took the number one position. Now London has taken it back. The UK capital’s return to the top spot is driven by record AI investment - $7bn in 2025, as well as being home to 138 unicorns, including Wayve, Granola, OLIX and ElevenLabs. This year the UK has continued to fly and has attracted 48% of all European Venture capital. Amazing news for London, and a great report as always from @yoramdw, @smorla, @sabben and the team (link in comments).
