Freestyle alternatives
Neutral ranking · no paid placement · verified 2026-08-09
Looking for a Freestyle alternative usually means one specific thing changed in your requirements. Start from what you need to move on (a lower rate, a faster start, GPU access, or stronger isolation), then pick from the list below. For reference, Freestyle itself is best for coding agents that need a real, long-lived Linux computer with Git rather than an ephemeral runner.
| Alternative | Isolation | Cold start | $/vCPU-hr | Why consider it |
|---|---|---|---|---|
| Blaxel | microVM | 25ms | $0.083 | native MCP support. |
| Cloudflare Sandbox SDK | V8 isolate + container | 50ms | $0.072 | native MCP support. |
| Daytona | Docker container | 90ms | $0.05 | adds GPU access, native MCP support. |
| E2B | Firecracker microVM | 150ms | $0.05 | Teams that want the cleanest SDK and strong microVM isolation for agent code execution. |
| Northflank | Kata / gVisor microVM (selectable) | 300ms | $0.01667 | cheaper per vCPU-hr ($0.01667 vs $0.04), adds GPU access. |
| Fly.io Machines | microVM | 300ms | $0.07 | adds GPU access, native MCP support. |
| Vercel Sandbox | Firecracker microVM | 400ms | $0.128 | Teams already on Vercel building JS/TS AI apps. |
| Runloop | microVM | 400ms | $0.108 | native MCP support. |
| CodeSandbox SDK | Firecracker microVM | 500ms | $0.05 | Web-development agents that fork and branch environments frequently. |
| Modal | gVisor | 800ms | $0.14 | adds GPU access. |
| Beam | Container | n/a | n/a | adds GPU access. |
| Fly.io Sprites | Firecracker microVM | n/a | $0.07 | Agents and dev workflows that need a persistent, resumable Linux environment with fast checkpoints. |
| Together Code Interpreter | Managed isolated sandbox | n/a | n/a | RL pipelines and agents that need cheap, high-concurrency Python execution priced per session. |
| Deno Sandbox | V8 isolate | n/a | $0.05 | Running untrusted JS/TS or LLM-generated code inside a Deno Deploy app, billed only for CPU time used. |
| Blacksmith Sandboxes | Full VM | n/a | n/a | Coding agents bottlenecked by build/test speed that need full, CI-identical VMs with Docker. |
| AWS Fargate | Firecracker microVM | n/a | $0.04048 | Teams already on AWS/ECS/EKS wanting Firecracker-isolated container compute for longer-running or untrusted workloads. |
