Podflare is a cloud sandbox platform for AI agent developers. It provides KVM-isolated microVMs with 46 ms first-exec latency, a fork primitive for tree-search agents, and a persistent Python REPL. The free tier includes 10 concurrent sandboxes with a 30-minute max lifetime. Pro starts at $50 per month with 4 GB RAM and 8-hour sessions.
Podflare is a cloud sandbox service for AI agents launched in 2026. It runs hardware-isolated Linux microVMs using KVM, with 46 ms first-exec latency and a fork primitive that creates copies in 80 ms. Sandboxes include persistent Python REPLs, writable filesystems up to 64 GB, and internet access. Free tier available; paid plans start at $50 per month.
Frequently Asked Questions
What is Podflare and what does it do?
Podflare is a cloud sandbox service that gives AI agents hardware-isolated Linux microVMs to execute code safely. Built on KVM virtualization, each sandbox runs a dedicated kernel and reaches first execution in 46 ms, with a persistent Python REPL that keeps variables and imports alive across tool calls. It integrates with Claude, OpenAI Agents, Vercel AI SDK, LangChain and Gemini through Python and TypeScript SDKs, plus an MCP server at mcp.podflare.ai. Podflare has not completed a third-party security audit yet: SOC 2 Type II is targeted for Q3 2026, and a HIPAA BAA plus GDPR DPA are in progress for Enterprise customers, alongside EU-only data residency routing available today.
How much does Podflare cost in 2026?
Podflare has a free tier plus three paid plans. Free includes a $200 new-account credit, 1 GB RAM, 2 vCPUs and up to 10 concurrent sandboxes with a 30-minute max session. Pro is $50 per month (4 GB RAM, 4 vCPUs, 50 concurrent sandboxes, 8-hour sessions) and Scale is $200 per month (16 GB RAM, 8 vCPUs, 500 concurrent sandboxes, 24-hour sessions); Enterprise is custom. All paid plans add pay-as-you-go overages of $0.05 per vCPU-hour, $0.016 per GiB RAM-hour and $0.09 per GB egress.
Is Podflare free to use?
Yes. New accounts get $200 in credit automatically with no credit card required, covering roughly 4,000 vCPU-hours at the pay-as-you-go rate. The free tier runs 1 GB RAM, 2 vCPU sandboxes, caps at 10 concurrent sandboxes, and sessions idle out after 5 minutes with a hard 30-minute maximum. Once the credit runs out, continuing requires a paid plan starting at $50 per month.
What are the best alternatives to Podflare?
E2B also runs microVM-isolated sandboxes and has a larger base of public documentation and integrations, though its cold-start latency runs near 200 ms versus Podflare's 46 ms. Daytona targets persistent, Codespaces-like workspaces rather than short-lived bursts, and Modal offers serverless Python functions with GPU access for teams that need model inference. Cloudflare Sandbox, which reached general availability in April 2026, is worth evaluating for teams already built on Cloudflare Workers. Podflare remains the only one of the four with a sub-100 ms fork primitive for branching agent execution.
How does Podflare compare to E2B in 2026?
Podflare benchmarks a 46 ms first-exec latency against roughly 200 ms for E2B, and its fork primitive clones a running sandbox in under 100 ms, a capability E2B does not offer. E2B has been in the market longer, with more third-party integrations and public documentation as of September 2026. On price, Podflare's Pro plan is $50 per month versus roughly $150 per month for E2B's comparable tier. Choose Podflare for latency- or fork-sensitive agent architectures; choose E2B if documentation and community maturity matter more than raw speed.
