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.

Agent Drive now supports fine-grained access control rules and path scoping. Define which sandboxes, agents, or jobs can mount an Agent Drive, and let your agent swarms collaborate without sacrificing security. docs.blaxel.ai/Agent-drive/P…

Blaxel sandboxes now come with built-in scheduling. Run commands on a cron schedule, at a future date, or after a delay - no external scheduler needed. Every run is logged with its full execution history. docs.blaxel.ai/Sandboxes/Sch…

Super excited to welcome @MichaelStolarz to Blaxel! Michael is one of those rare builders who combines technical range with an obsession for making complex systems actually usable. He has built SystemSculpt and other AI-native tools used by tens of thousands of developers, worked across full-stack engineering, automation, QA, security, and agent workflows, and has a sharp instinct for turning ambiguous technical friction into clear, actionable, repeatable paths to success. At Blaxel, he’ll focus on DX/AX: making our agent infrastructure easier, faster, and more reliable for both human developers and the AI agents operating it. Welcome, Michael. Let’s build!

OpenCoDesk — open-source cloud-based alternative to @claudeai cowork which works in the cloud. Upload Excel → agent analyzes it in a sandbox → artifacts on a persistent drive → showFile preview live browser preview. Uses • Agent Drives (files survive across threads) by @blaxelAI • Resumable sandboxes preview URLs also by @blaxelAI • showFile / showBrowser canvas powered by @assistantui • Session folders markdown memory wiki based on @karpathy’s LLM Wiki Opensource repo link in comments.

Latency is becoming the most important criteria for agents on @blaxelAI

.@Runworkai switched to Blaxel and cut sandbox time-to-interactive from 20 seconds to just 2–3 seconds. Now they have faster agents, lower costs, and a better DX. Read the full case study on Blaxel Blog. blaxel.ai/blog/runwork-accel…

YC S26 founders: you get $100K in Blaxel credits. As YC alums, we experienced firsthand how hard it is to find infra that keeps agents fast, reliable, and scalable. So we built Blaxel. Today, 100 YC startups (S13-W26) run on Blaxel. Get started now! Congrats P26 on Demo Day!

New for sandboxes: fallback previews! Instead of returning a 404 when a preview URL doesn't exist, you can now route unmatched requests on a custom domain to a designated fallback preview. docs.blaxel.ai/Sandboxes/Pre…

we put up billboards in SF. for infrastructure made for AI agents. which is funny, because an agent is never going to drive down the 101 and look up. the billboard is for the humans. anyways, it's up there! send pictures if you spot one

.@blaxelAI sandboxes are persistent and can be resumed from standby quickly (~25ms) docs.blaxel.ai/Tutorials/Cla…

Deploy your self-hosted sandboxes in minutes: docs.blaxel.ai/Tutorials/Cla…

Why CodSpeed chose Blaxel: Speed: 25ms resume from idle, no time lost rebuilding repo context. Security: the agent runs proprietary customer code, on infra they already trust. Control: their own profiling tools and a custom networking layer to inject tokens

@CodSpeedHQ builds an agent that makes your code faster, automatically. Claude Managed Agents runs its harness. Blaxel sandboxes run the code execution: the agent edits, benchmarks, and compares in-sandbox until it finds improvements worth keeping.

Claude Managed Agents is now available on Blaxel. Run your agent loop on @ClaudeAI managed infra, while running tool execution on secure, persistent sandboxes. -> 25ms suspend/resume. Shared persistent filesystem. Controllable network. x.com/ClaudeDevs/status/2065…

We've made it even faster to start building immediately with coding agents. Our CLI now lets you instantly create sandboxes with Claude Code and Codex preinstalled.

We'll be at #MCPDevSummit Mumbai this weekend, focusing on some challenges of multi-agent systems: shared state, execution isolation, and agent hand-offs. If you're interested in orchestrating agent swarms with sandboxes and shared filesystems, this talk is for you! mcpmumbai26.sched.com/event/…

Get started with Blaxel Stripe Projects today: blaxel.ai/blog/stripe-projec…

Blaxel is now integrated with Stripe Projects! Now, agents (and humans) can spin up accounts and resources from the terminal directly through @Stripe, and get back credentials without dashboard hopping. x.com/stripe/status/20647276…

Keeping sandboxes warm shouldn't mean paying for idle infrastructure. Our blog post goes deep into this, explaining how snapshot-based standby architecture minimizes idle compute expenses. blaxel.ai/blog/how-to-keep-s…
