congrats charlie and team if you need a new home, @tembo: - self-host on your own infra - runs claude code, codex, cursor, opencode, amp, pi, grok build, antigravity - run as many agents at once as you want - each gets its own linux VM - no git worktrees - any model: claude, gpt, gemini, grok, open source - use your claude, chatgpt or supergrok plan, or API keys - review diffs before the PR - sessions keep running when you close your laptop - preview builds in your browser - 60 FPS remote desktop - fork a teammate's session - agent templates - API, SDK and MCP - agents have their own accounts - github, jira, linear and more - VMs auto scale up to 128 GB mem - VMs ~20% cheaper than E2B or Daytona tembo.io

I am very excited to share that Conductor is joining Meta! We have some big, crazy plans for the next interface. If you liked Conductor, you’re gonna love what’s coming. We’re super excited to work with @natfriedman and @alexandr_wang at MSL to build it. They’ve been on an absolute tear, and I’m convinced MSL has the highest talent density of all the labs. A huge thank you to our earliest believers @aaron_epstein, @ilyasu, and @nabeel. And to everyone here who tried Conductor, sent us feedback, and prompt requests - you made this so much fun. Thank you ❤️🚂 Choo choo!

we were harness agnostic all the way back in august of 2025 being able to just switch to the best model + harness combo whenever you want is table stakes now

Introducing voxl extremely fast remote desktop streaming written in rust → 60 fps + low latency → macOS, Windows and Linux → One WebSocket, so it works through proxies and sandbox portals → Agent APIs: /screenshot, /record, /wait

this is huge for frontend animations and moving pieces are half the job - over normal VNC streaming they come through choppy voxl, our in-house stream engine, runs at a near-constant 60 FPS you will FEEL the difference want tembo for your org? dm me, i'll get you sorted

See what your agent changed before there's a PR. A Tembo session's Changes tab shows the diff. Comment on any line, send your review to the agent, and open the PR when it's ready. How it works → tembo.io/blog/review-coding-…
A Tembo session's Changes tab listing three changed files and an Open PR button, with a diff of checkout-button.tsx and a pending review comment on one line.

Recently did a PR analysis for a customer; 9 of 10 PRs were fixes/defense. Many many teams are in catch up mode, not value creation mode. It's not just engineering either. A CX team manually walking customers through half-built onboarding is playing defense. Missing out on huge opportunity to attack their market.

coding agents on laptops are great for solo devs but for high-performing teams, agents are moving off the laptop when agents run in a shared cloud session: - you can parallelize easier - handoffs become effortless - you can see how teammates actually work

Tembo VMs starting at $0.11 per hour, 20% cheaper than E2B and Daytona. Nano 2 vCPUs 2 GiB $0.11/hr, Medium 4 vCPUs 8 GiB $0.27/hr, Large 8 vCPUs 16 GiB $0.53/hr. Headline: Big machines, small bill.

coding agents don't remove the engineering bottleneck, they concentrated it the same people on your team who are running agent farms... are usually the best ones to merge other people's PRs... but they probably wont, because they are already busy af

🍬 anything is possible 🍬 @tembo gives you full power to create an agent with precise control over coding agent harness, model, and VM config/deps.

No tricks, just treats. 🎃 Writing an agent from scratch is the scary part. So start from a Tembo template instead: - Turn Linear issues into PRs - Fix new Sentry errors before they haunt you - Keep docs up to date Tweak it for your repos and go. tembo.io/agent-templates
Tembo agent templates list: Write PR descriptions, Turn Linear issues into PRs, Keep docs up to date, Fix new Sentry errors, Review every pull request, each with a Use template button. Headline: Start from an agent template.

Our devs moved off local editors and harnesses thanks to Tembo Computer, Projects, Snapshots, and warm VMs. Sessions start with every dep installed, all repos cloned, and the app already running in a tab on a real computer. Local dev is dying.
