E2B

Machines for AI agents | Hiring! 👉

[E2B @e2b]

We have just launched the E2B deal for YC founders. 🫡

20 YCombinator startups are joining the first batch of the deal. We are proud to support companies like Rivet, Redouble, or Prox with use cases like:
🔸 LLMs safety benchmarks
🔸 Cursor-like coding assistants for accountants, biologists, and social scientists
🔸 AI that generates, tests, and deploys full-stack apps from natural language
🔸 User simulator environments for training collaborative AI agents
🔸 RL environments for evaluating dataset quality
🔸 Cybersecurity agents that run penetration tests in sandboxed containers.

See the deal is live on Bookface. To check out other E2B startup programs, look for "E2B for Startups" on our web.

@nbushak @OpenAI @thsottiaux Congrats on the launch!

[Vasek Mlejnsky @mlejva]

Being open source used to be about developers. Now it's also about models.

When you open source your code, you're not just making it easier for a human to integrate you. You're letting the labs train on it. The model learns you exist. It learns your API. Agents start recommending you and onboarding your users before they ever open your docs.

That shift is one of the things I got into with Nasdaq's Kristina Ayanian: where AI infrastructure is heading, and how LLMs are reshaping the industry that trains them.

@mlejva @speedrun The only thing faster than spinning up our sandboxes is how quickly these teams are going to ship 🚀

[E2B @e2b]

Excited to announce that we’ve just launched the E2B offer for the a16z @speedrun program!

If you want your AI agents running on fast, reliable, and production-ready infrastructure, this one's for you.

Offer is valid for all a16z speedrun participants and alumni. Learn more and claim it on the Speedrun offers page.

[E2B @e2b]

@_jcube @speedrun Proud to be making building easier for startups!

[Vasek Mlejnsky @mlejva]

back in 2023 - me posting on HN about building @e2b - a cloud runtime for AI agents:
- 6 responses
- 19 upvotes

No one cared at that time. Yet building for the future was essential for us.

[E2B @e2b]

Just in time for the weekend: you can now update your E2B sandbox network configuration at runtime with the latest SDK.

[Vasek Mlejnsky @mlejva]

Pssst... spotted on Times Square again, this time, with a sneak peek of our new logo.

Honored to be included in @Redpoint’s 2026 InfraRed 100 alongside transformative companies in cloud infrastructure that power the next wave of AI.

E2B gives AI agents computers with real-world tools: file I/O, browsers, terminals, and more.

Agents that can actually do things are only possible with the right infrastructure. Proud to be building it.

[Haystack @Haystack_AI]

We're so happy that @e2b is now available as a tool integration in Haystack. Give your agents direct access to isolated Linux sandboxes for code execution, file operations, and command-line interactions - all without leaving your pipeline.

E2BToolset lets agents write scripts, run code, and explore filesystems inside secure, ephemeral environments. Perfect for coding assistants, data processing tasks, or any agent that needs to execute code safely.

@saksham_sarda 💪💪

[E2B @e2b]

Turns out 12 weeks of engineering takes about 48 hours when @obvious' agents are writing the code. We had to see it, so we’ll be at the after party this Friday.

Come meet the builders, hear what held up and what didn't, and talk shop with people who are figuring out the same things you are.

[Ethan Nsquare @tknsquare]

Just got accepted into @e2b for Startups: $20K credits + Pro Tier.

Building in stealth on the AI agent side. E2B handles all the sandbox infra so we can keep shipping.

If you're early-stage and building agents, check if you're eligible: https://t.co/TWAhO40zSi

[E2B @e2b]

Agents need two things that rarely come together:

- Durable execution and indefinite context
- Fast, isolated, snapshottable runtime

With Temporal Technologies × E2B, you can build long-running agents that are scalable and secure. Check out Temporal's new blogpost for running sandboxes inside Temporal Workflows. It handles the lifecycle plumbing every agent team rebuilds: provisioning, retries, auto-pause, and snapshot-based persistence.

100K sandboxes concurrently? We're in for the challenge.

The ComputeSDK team is benchmarking top providers under the same production-like load on June 1st. Same workload, same metrics, results published openly.

Follow along to keep posted on the results of the benchmark event.

[ComputeSDK @computesdk]

Announcing the 2026 ComputeSDK Scale Invitational.

The Maui Invitational for AI sandbox scaling. June 1st. RSVP Below.

100,000 concurrent sandboxes. One day. Every provider on the same playing field.

[Zijus @zijus]

Excited to share that Zijus has been accepted into the @E2B for Startups program.

We’ve received $20K in E2B credits + access to E2B Pro Tier.

@zijus welcome!

[E2B @e2b]

Now add a few zeroes!
