@mlejva Building agent systems for finance is a different game. New ways of interacting with sandboxes emerging depending on workload, still early!

How do you deploy AI agents for financial institutions without compromising on security, isolation, or scale? Rogo powers complex research, analysis, and deal workflows for leading financial firms, supporting complex tasks across tens of thousands of concurrent users. To meet the diverse needs of financial teams, Rogo relies on both specialist and general-purpose agents that can adapt to a wide range of workflows. With Claude Managed Agents and self-hosted sandboxes, Rogo gets the orchestration and post-training capabilities needed to design these agent systems, while E2B provides the execution layer underneath. Every piece of code generated by an agent runs inside its own E2B sandbox with full auditability and traceability. Each sandbox is powered by an isolated microVM, providing the kernel-level isolation critical for Rogo's customers. The result is a seamless agent experience backed by the security, reliability, and compliance requirements that financial institutions demand.

We're launching @niteshiftdev – the full-stack cloud for coding agents Verification is the new bottleneck. Software teams can now define their dev environment and verification tools once. Then run any frontier agent in the cloud: Claude Code, Codex, or OpenCode

I had a great time working with the stripe team on this! stripe projects init my-app → E2B sandbox, authenticated and ready to go. Give it a try!
E2B@e2b

Excited to announce that E2B sandboxes are now available through Stripe Projects. As part of the Stripe Projects developer preview, developers and AI agents can now provision and authenticate E2B sandboxes directly from the CLI. We're proud to be working with @stripe on the future of agent infrastructure and the Agentic Provisioning Protocol. Try it: install the Stripe CLI stripe projects init my-app stripe projects add e2b/sandboxes Full announcement is in the comments.

Genspark's mission is to help a billion people become AI specialists. The infra they run that mission on is E2B. Honored to be a small part of it.
Vasek Mlejnsky@mlejva

Stories like this is why we built E2B. Watching @genspark_ai go from zero to $250M ARR in 12 months on our infrastructure is one of the best feelings in this job. Their Super Agent does deep research, runs analysis, and builds decks. Millions of users, with every session running on E2B: a real, persistent computer for the Super Agent with all the tools it needs. Here's what Kay Zhu, co-founder and CTO of Genspark, had to say about our collaboration: "A 30-step agent run can't start with a 60-second cold start. It has to feel instant. E2B lets us scale to thousands of concurrent sessions, and we couldn't have hit $250M ARR if five of our engineers were building a sandbox platform instead of the agent." Genspark is building one of the defining products of this generation, and we get to be the layer underneath. Hard to ask for more than that.

E2B@e2b·
Security won't affect 99% of your day-to-day with a sandbox provider. But the 1% outweighs the other 99% combined. CVE-2026-31431 is the 1%. Root on every Linux since 2017, cross-tenant on shared-kernel hosts. If your sandbox provider runs in containers, you should immediately check whether they're exposed to this. E2B isn't affected, by design. Here's why: Per-sandbox kernels. Every E2B sandbox runs in its own Firecracker microVM. Own kernel, own memory, own page cache. Bugcrowd's analysis of Copy Fail puts it cleanly: the boundaries that hold are the ones that don't share a kernel. A kernel exploit inside the sandbox cannot reach the host: the attacker would need a Firecracker escape on top of the kernel bug. The module isn't compiled in. We build custom minimal kernels for agent sandboxes. These run code interpreters, drive browsers and CLIs, power RL rollouts, and host long-running agents. CONFIG_CRYPTO_USER and CONFIG_CRYPTO_USER_API_AEAD have never been enabled, cause they're not needed by AI agents. ‍Fewer, purpose-built features mean fewer places for vulnerabilities.

@thsottiaux ssh + tmux so doesn't die when disconnected (so i guess logs into codex on that box too)

Send us feature requests for codex in the form of an images 2.0 generated image. It makes it easier for codex to implement if we decide to go for it. Saw some good ones today already that codex is cooking on.

Bring your own environment. The Agents SDK now supports sandbox execution with providers including @Cloudflare, @Vercel, @modal, @e2b, and more. Keep files, credentials, and execution state in your environment while passing approved context to the model.

today every agent needs a sandbox. tomorrow, many. keeping the frameworks open source helps figure out bad assumptions quicker and focus on building what we really need.
E2B@e2b

OpenAI x E2B: build your agents with the new OpenAI Agents SDK, powered by E2B sandboxes. We're excited to support OpenAI as a launch partner! The new @OpenAI Agents SDK will now get dedicated sandboxes - perfect for persistent, long-running agents. With E2B, you'll get a custom environment with resource isolation and security boundaries, with no infrastructure setup required. Your agents will be able to: - Edit files and run shell commands in isolated environments - Maintain temporary workspace state across steps - Produce artifacts you can review before publishing - Run multiple sandboxes in parallel for concurrent workloads - Generate frontend output with live preview URLs ... and more, with a few lines of code! Learn more and see the end-to-end example in the thread:

We’ve spent decades building compute for humans. That’s about to change. I’ve decided to join @E2B to do it. Throughout my career at @Apple, @conduitxyz, and @WishShopping, I’ve worked to deliver fast, reliable, scalable systems that serve users better. But the definition of “user” is shifting.

E2B just made the 2026 Enterprise Tech 30. The list includes Anthropic, OpenAI, Cursor, Stripe, Databricks, SpaceX, Vercel, ElevenLabs, and Canva. Past ET30 alumni: Snowflake, Datadog, Confluent, UiPath, HashiCorp -- all before IPO. wing.vc/et30 #ET30
Vasek Mlejnsky@mlejva

Big news - @e2b is one of the 2026 Enterprise Tech 30 firms. Very proud to be one of the leanest teams (of just 16 people) to make the list. We're in a good company, too - excited to be included alongside our customers and partners. Now back to building! ________ The ET30 is voted on by 90+ of the top investors, recognizing private companies shaping the future of enterprise technology. Thank you @Wing_VC and @EricNewcomer for including us on the list! wing.vc/et30/list #ET30

We're introducing 𝗔𝘂𝘁𝗼 𝗥𝗲𝘀𝘂𝗺𝗲 𝗳𝗼𝗿 𝗦𝗮𝗻𝗱𝗯𝗼𝘅𝗲𝘀 Many agents don’t need a sandbox running all the time, but when they do need it, it should just work, whether it was paused or not. Auto resume handles this 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗰𝗮𝗹𝗹𝘆. A paused sandbox wakes up when activity arrives. Perfect for use cases such as 🔸 agent runs on request 🔸 active dev previews on inbound traffic Great ship by @badphilosopher!
