I judged and co-sponsored a hackathon yesterday with a @tryreplicas track. Pretty crazy having people ask me about Replicas and being a YC founder when a few years ago I was the one standing in line asking organizers those same questions. A truly full circle moment

Small milestone: @tryreplicas crossed 1M agent minutes toda I think we'll be at 2M in a few weeks, but looking back on the work it took to get here is very rewarding :)

Replicas now has access to a Canvas where it can show you plans, HTML reports, and media. Here it is in action telling me about the Knicks vs Spurs!

I joined @tryreplicas as CTO a few weeks ago. Since then we’ve shipped nonstop, grown faster than ever, and become even more convinced of the vision: Every engineering team should be able to run any agent harness and deploy autonomous engineers. Excited for replicas V2‼️
I joined Y Combinator with 14 users, building a dev tool for myself. Then @SaaiArora joined as CTO, and we started growing and shipping 2x faster. It forced us to rebuild product and infra from the ground up for teams, not solo devs. We are ending the batch with >300k agent minutes per week, and teams like @mintlify, @knowunity, and @modaflows shipping through Replicas every day. Today we're launching Replicas V2.

Whenever Replicas takes a screenshot using Computer Use, it now gives to you in cleanshot/screen studio-style! here was a screenshot it took playing the Ubuntu Star Wars:

We’ve replaced the codex sdk with the app server protocol; this allows us to better integrate with the codex harness. I’ve been using the /goal command a lot with gpt 5.5, and it’s been a game changer. Try it out in replicas.

every couple weeks I bump up the disk GB on Replicas agents and go “yup, that’s more than enough” then some customer pings me asking for 2x more? so I gotta ask our sandboxing provider for more limits, and their poor engineer has to explain to me that performance will be “unpredictable” meanwhile I don’t even know how or why they need so much

Devin is a great product. But they miss one thing: developers are emotional and pick tools based on vibes. That's why most devs run Claude Code or Codex as their daily driver. We're building @tryreplicas to automate software engineering while letting you use ANY harness you want. Even Devin. Even Cursor. Even our competitors. That's why we'll win.
1/ We’ve raised over $1B at a $26B valuation, led by @Lux_Capital, @generalcatalyst, and @8vc. Our enterprise usage has grown >10x since the start of this year, and our run-rate revenue grew to $492 M. We launched Devin two years ago as the first AI software engineer. Since then, cloud agents have gone from niche to mainstream, and today they are the fastest growing way to create software.

I told @tryreplicas to update our logo on github and this is what it responded with, along with a video uploading it

Replicas now leaves this table on your pull requests showing all the CI/CD checks that it fixed probably better than the comments it used to spam

Opus 4.8 is now available in @tryreplicas ! We also are very fond of Dynamic Workflows, so that's coming soon 👀
May 28
Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors. Available today at the same price.

You can make sure PRs never introduce unused code in 2 clicks: 1. Enable the "No Unused Code" automation 2. Get a CI check on every PR, that comes with an explanation 3. Point your CC/Codex at CI and have it autofix (or have Replicas auto fix)

We added multimodal output for Claude Code and Codex! (kinda) Replicas can now show you videos, images, or audios rendered inline - before uploading it to a library for you to look at. Take a look 👇

Does your Claude Code add too many comments? Fix in 2 clicks: 1. Enable the "No Unnecessary Comments" automation 2. Get a CI check on every PR, that comes with an explanation 3. Point your CC/Codex at CI and have it autofix (or have Replicas auto fix)

Update for May 27th, 2026 Major updates: - Automations can now override organization defaults with custom coding agents, models, and thinking levels per automation - API now accepts a size param (small/large) to control per-workspace compute resources and pricing - Media sharing streamlined: Agents now share media through Replicas with View-in-Replicas deep links instead of external hosts UI/UX: - Computer Use refresh with modern Yaru theme, Bibata cursors, larger dock icons, and abstract wallpaper - Fixed Codex ASP tool calls disappearing after refresh

Can’t wait to see what everyone builds
hot take: most hackathon projects end up as toy apps because people barely get to build. half the day disappears into setup: > picking a tech stack > running endless npm install commands > writing glue code then you have 3 hours left to build the actual idea, and it still breaks during the demo. we want to change that. with @insforge, we provide your entire stack (deployment, model gateway, database, auth, payments, compute, and more) in one platform. all agent-native through CLI skills. you get past the boilerplate and setup in 10 minutes, not half the day. the rest is pure building with your agents flying at full speed. InsForge Hackathon is a 1 day SF hackathon for agentic devtools and agentic infra. saturday, june 6, 8 AM - 9 PM PDT at the @join_ef office @vercel, @cognition, and @tryreplicas are in. the challenge: push the limit of what can be built in one day with the newest agentic dev stack. not a generic LLM wrapper. the prize: we’re giving away Mac minis, because every agent builder needs a little server for their own agents. not a boring cash prize. come see what the future of software development feels like.
