Blaxel
Persistent microVM sandboxes that resume in ~25ms for autonomous AI agents.
Blaxel is the infrastructure to choose when your agents need persistent state and serious scale—it solves the state-loss problem that plagues ephemeral sandboxes. If you're building autonomous coding or browsing agents that run for hours, the ~25ms resume and $0 idle cost are compelling. However, it's raw infrastructure: you'll need engineering and an agent framework on top. For simpler needs, consider E2B or Fly Machines; if you need pre-built agent logic, look at LangChain or CrewAI.

Skip Blaxel if you need a turnkey agent framework or no-code builder—this is raw infrastructure that requires engineering effort and your own agent orchestration.
Active CPU time is billed per GB RAM per second, so a memory-heavy sandbox running continuously can rack up costs quickly.
Blaxel's usage-based pricing (no base subscription) fits teams that scale with actual usage—you only pay for active CPU time and storage. It's more cost-effective for spiky, stateful workloads than per-seat platforms, but for steady, low-memory use, a flat serverless provider might be cheaper.

About Blaxel
Blaxel is cloud infrastructure designed specifically for autonomous AI agents, giving each agent its own secure microVM that boots in milliseconds and resumes from standby in about 25ms with memory state intact. Unlike traditional serverless functions or short-lived sandboxes, Blaxel environments auto-suspend when idle—at zero compute cost—and pick up exactly where they left off, eliminating the need to build custom state management. The platform bundles the primitives agents need: compute (sandboxes, batch jobs, MCP hosting), storage (Agent Drive distributed filesystem, durable volumes, in-memory filesystem with snapshots), and networking (outbound allow-listing, static IPs, managed egress proxy, model gateway). You control what agents can reach, keep credentials out of the sandbox with secret injection, and route model calls through one co-located endpoint for every provider. The TypeScript-first SDK (Python at parity) lets you spin up Blaxel from just a few lines of code, and existing Docker images can be templated for fast, repeatable creation. The platform scales to 50,000+ concurrent sandboxes and up to 512 TB of volume storage with tier-based quotas. Deployment options include managed cloud, self-hosting, and VPC, and security certifications (SOC 2, HIPAA, ISO 27001) make it viable for regulated workloads. In July 2026, Blaxel ranked top 2 across 6 performance metrics in the StarSling sandbox benchmark, and a partnership with Sapiom now lets agents provision their own sandboxes via crypto wallets with spend controls. Pricing is fully usage-based with no base subscription—you pay only for active CPU time (by GB RAM per second), snapshot storage, and image storage. This makes Blaxel a strong fit for production teams running many stateful agents, but it's raw infrastructure, not a pre-built agent framework, so it won't suit beginners or those who want turnkey bots.
Behind the Verdict
Blaxel sits in a crowded but distinct niche: persistent, stateful sandboxes for AI agents. Its core differentiator is the combination of fast resume (~25ms) and idle-to-zero cost, achieved via snapshot-based suspension. This directly addresses a major pain point for agent developers—losing workspace state between runs. The platform's components are thoughtfully packaged: compute, storage, and networking are all first-class features. Agent Drive is a notable addition, enabling multi-agent collaboration through a distributed filesystem, which is rare among competitors. The networking suite (outbound control, static IPs, proxy with secret injection) gives you fine-grained security controls that many sandbox providers lack. The model gateway simplifies provider integration, keeping your stack portable. Performance-wise, ranking top 2 in 6 metrics in the StarSling benchmark (July 2026) is a strong signal for speed-sensitive workloads. The Sapiom partnership, letting agents self-provision sandboxes with spend controls, is forward-thinking but niche. Weaknesses: The Agent Runtime (session-first, stateful) is still 'coming soon,' so long-running session management isn't fully there yet. There's no built-in agent orchestration or framework—you must bring your own. Pricing is transparent but can be unpredictable; you're billed per second of active CPU, which could be a surprise if you have many agents. Also, as a relatively new platform, integrations are still evolving. Where it fits: production teams running many stateful agents, especially those with security or compliance requirements (SOC 2, HIPAA, ISO 27001). Where it doesn't: beginners, no-code builders, or teams wanting a turnkey solution.

Real-world workflow fit
Concrete scenarios for the personas Blaxel actually fits — and what changes day-one when you adopt it.
Deploy an autonomous coding agent that needs a persistent workspace across multiple sessions, with secure access to internal APIs.
Outcome: Engineer writes a TypeScript script using Blaxel SDK, provisions a sandbox, and the agent resumes in ~25ms with full state intact across runs, reducing cold starts and state management overhead.
Run a large-scale batch job to process millions of records with isolated sandboxes and static IPs for web scraping.
Outcome: Spawns thousands of batch jobs across sandboxes in seconds, each with its own IP, and pays only for active compute time, cutting costs compared to always-on VMs.
Host an MCP server on Blaxel to expose internal tools to agents with private networking and secret injection.
Outcome: MCP server runs as a first-class workload on the same private network, keeping tool calls internal and secure, with compliance certifications (SOC 2, HIPAA) meeting regulatory needs.
Use Cases
- Run an autonomous coding agent with persistent workspace across sessions
- Deploy thousands of parallel web scraping agents with isolated IPs
- Collaborate with multiple agents sharing a distributed filesystem (Agent Drive)
- Host an MCP server for tools that agents can call privately
- Schedule nightly batch jobs for data processing across sandboxes
- Let agents self-provision sandboxes via Sapiom wallets with spend controls
Limitations
- Blaxel provides persistent microVM sandboxes with ~25ms resume times and scales to 50,000+ concurrent machines.
- The Agent Runtime is marked as 'Soon', indicating session-first, stateful runtime for long-running agents is not yet released.
- The platform is relatively new and integrations may still be evolving.

Where the pricing makes sense
The company stage and team size where Blaxel's pricing actually pencils out — and where peers do it cheaper.
Blaxel's usage-based pricing (no base subscription) fits teams that scale with actual usage—you only pay for active CPU time and storage. It's more cost-effective for spiky, stateful workloads than per-seat platforms, but for steady, low-memory use, a flat serverless provider might be cheaper.
Setup time & first value
How long it actually takes to get something useful out of Blaxel — broken out by persona, not the marketing-page minute.
For a developer familiar with Blaxel, you can spin up your first sandbox in under a second using the SDK or CLI. A basic agent with persistent state might take 30 minutes to set up, including configuring storage and networking. For a full production environment with MCP servers and batch jobs, expect a few hours to a day.
Switching to or from Blaxel
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From E2B: Port your sandbox configurations and use Blaxel's persistent storage to maintain state across sessions, reducing cold starts.
- →From Fly Machines: Reuse Docker images and adopt Blaxel's auto-suspend to cut idle costs, with a similar API for spawning machines.
- →From AWS Lambda: Refactor stateless functions to stateful agents using Blaxel's volumes and Agent Drive, leveraging the SDK for easier setup.
- ↗To E2B: Move your sandbox orchestration code, but you'll need to handle state persistence externally if you require long-lived state.
- ↗To Modal: Adapt your scripts to Modal's API, but you may lose some of Blaxel's networking features like static IPs and proxy.
- ↗To Fly Machines: Replicate sandbox environments as Fly Machines, but you'll need to manage auto-suspend and state persistence yourself.
