Netlify

In 2019 we launched Netlify Functions. In 2023, Functions 2.0 rebuilt the whole experience around Developer Experience. Today we're taking it to the next frontier: Agent Experience. Here's what shipped. 🧵

Congrats to this week's winners! 🎉 Want to see your build here next Friday? Ship something, submit it, and tag @Netlify. Browse everything shipped so far: hot-ar-summer.netlify.app/showcase

🥉 Winner 3: Literal Agent Runners by Ash Wesley What actually happens behind the scenes when you click "Build now" on an Agent Runners project? Now you know! hot-ar-summer.netlify.app/app/15

It's Friday, which means it's time to crown this week's #HotARSummer winners. 🏆 Three builds stood out this week. Meet the winners. 🧵

You can now deploy @vercel apps to Netlify.

That means we can see how agents will handle a new capability before we release it, not after. AXIS is free and open source: axis.run

The scenario is a real prompt plus a grading rubric, run twice: once without our skill loaded, once with. Same prompt both times, across Codex, Claude Code, and Gemini. Without the skill, agents reach for the classic pattern. That passes. With it, they pick up the new one.

We just shipped a new pattern for background functions. The old way, appending "background" to the filename, still works. The new way is setting background to true in your config. Both are valid. But we want agents reaching for the new one. So before shipping, we tested which one they'd actually pick.

380 apps built during #HotAppSummer! 🔥☀️ We launched it as a fun way for the community to build together at the start of the summer. Honest expectations were maybe 5 or 10 submissions. Then the public leaderboard turned it into an arcade high score chase. @taniacryptid and @thisiskp_ recap how it went:

Luna and Terra work the same way. Swap in 'gpt-5.6-luna' or 'gpt-5.6-terra' and deploy. All three run across every Function type and in Agent Runners. Full details and code examples in the changelog: netlify.com/changelog/gpt-…

New models, zero setup. OpenAI's GPT-5.6 Sol, Luna, and Terra now work out of the box in Netlify Functions and Agent Runners. const openai = new OpenAI(); model: 'gpt-5.6-sol' That's the whole integration. AI Gateway handles auth, caching, and rate limiting for you.

AXIS runs real agents against your service across different models and contexts, then scores the experience. Change the API, the docs, a skill, or the MCP server, and you can see whether agents handle it better or worse. Free and open source: axis.run

Testing an API used to be simple. The API works, the docs match, you ship. Then agents showed up. You don't know which one your user is running, what context it has, or what it decides to do by default. @seancdavis29 walks through what that breaks, and how AXIS measures it.

I just built my 9th app of #HotARSummer using @Netlify Agent Runners! 🌸 Meet Spell-a-Bloom, a custom spelling practice tool I created for my kids, with just a sentence like chatting with a friend, to help them master their words. So happy to watch my 10yo daughter is using this app to practice spelling!💜

@NolanMakatche @codetv_dev Shipstorm brought it. This was such a fun one to be part of, congrats on the episode!

It's out! Our episode of CodeTV's Greenfield Games is officially live. Six hours, one greenfield build. @codetv_dev Alongside my fellow Orchid AI teammates Matthew Elder and David Sadofsky, we went head to head with an incredible Netlify crew: Founder and CEO Mathias Biilmann Christensen, CTO Dana Lawson, and Principal Engineer Jack Herrington. @dreamcodezz @Netlify Watch the full episode (link in the comments) 👇 Huge thanks to Jason Lengstorf for having us on, and to Kedasha Kerr plus Replayio for hosting the show. @jlengstorf Thank you to Trey Kenyon and the whole CodeTV team for the support, our judges Jamie Turner (Co-Founder of Convex) and Max Brunsfeld (Co-Founder of Zed Industries), and Replayio founders Brian Hackett and Thomas Daly. Go watch, see what we built, and find out who came out on top!

Our founder, our CTO, and a Principal Engineer walked into a six hour greenfield build. Watch the episode to see how it went for them!
