What if Lambda and EC2 had a baby?
AI Agents are a new breed of workload. They need the instant startup of serverless, but the persistence of a full server for the context.
Traditional clouds force you to pick one, we decided to build both.
We moved to bare metal to give agents instant-launching, persistent sandboxes to run code and share context at scale.
⬇️ Read our technical deep-dive on the anatomy of this custom runtime for agents.

We just launched sandboxes made for agents
They are uVMs optimized for coding agents — meaning MCP-native and super low cold starts (boots in ~20ms and hibernates after 1 second of inactivity).

Okibi is built on Blaxel Sandboxes!
With 25ms boot times & persistent memory state, sandboxes provide secure dev environments to preview agents created by Okibi in real-time.
Congrats @MahyadGhassemi and @thesauravmitra !
Okibi (@okibi_ai) is an agent that builds agents – a web app that lets you effortlessly create automations and AI agents using simple, everyday language. Think Lovable, but for agents.
Congrats on the launch, @MahyadGhassemi & @thesauravmitra!

Launching our integration with @agentmail to give your agents their own inbox.
Here we’re talking with a customer support agent that can access any doc in the world in real-time — all via emails.

New: Set time-to-live (TTL) for your Blaxel sandboxes, to automatically clean up after experiments.
Perfect for short-lived environments where your agents can run adhoc scripts without requiring state persistence.

During YC, we had the privilege of working with amazing agent-native companies like @humanbehaviorai, @vybe_build & @jazzberryai.
We're already processing millions of agent requests daily across 16 global regions, saving our partners up to 50% on their infra costs.

how to auto-detect bugs from screenshots in your Linear tickets
we built a Linear knowledge base using @airweave_ai, and have an agent search it through our MCP server integration

And of course we vibecoded a codegen agent that uses sandboxes itself
Here is a chat-based Next app of a code generation agent built with AI SDK that previews the code in real-time inside a remote Blaxel sandbox: github.com/blaxel-ai/sdk-typ…

A huge thank you to our investors for believing in our vision and to our customers for trusting us with their agents.
The future is autonomous. Your infrastructure should be too.

We brought MCP to serverless workloads, using @supercorpai Supergateway.
This lets us run stdio-based MCP servers over WebSockets, which we found more reliable for serverless executions.

This is just the beginning. The shift to agent-based computing is happening FAST. Gartner predicts 75% of app dev will involve AI agents by 2028.
These billions of agents need a new kind of cloud. One built for them.

To build this cloud, it takes a world-class team.
We’re so proud to have assembled such a great team to build Blaxel: Paul Sinai, Christophe Ploujoux, Thomas Crochet, Charles Drappier, Mathis Joffre, and Nicolas Lecomte.

Why now? Today's AI agents are running on cloud offerings that were designed for the SaaS and Web 2.0 era, where the main users were humans.
It leads to slow performance, security risks, and spiraling costs. Developers spend more time fighting infra than building.
