@e2b/python-sdk 2.46.2 and 2.46.4, released September 2, default to sharding envd traffic across four pools so high-concurrency long-running streams don't all contend for one connection's stream limit, tunable via E2B_ENVD_POOL_SHARDS set before SDK import. Anyone running many concurrent agent sandboxes was hitting HTTP/2 per-connection stream caps with no obvious symptom. The same window shipped @e2b/desktop-python 2.4.6, which waits for the XFCE session to be ready before returning a new Desktop sandbox.

Firecracker + CoW mmap forking spawns KVM-isolated sandboxes in 0.79ms p50 with 265KB memory per instance — versus E2B's ~150ms and ~128MB. At this scale, sandboxed code execution becomes viable inside interactive agent loops where latency directly impacts UX. GitHub ---
Released yesterday, one day after 0.21.0, v0.21.1 adds model call timeouts, run-scoped sandbox working directories, network-disabled Docker sandboxes and Modal sandbox resource options (GitHub). It also fixes the core honoring exact call-approval decisions and rejecting partia...

elie222/rakazo appeared Aug 13, Apache-2.0, TypeScript, explicitly bring-your-own model and sandbox (tested against Docker, E2B, Daytona) with the Pi runtime underneath and OpenRouter, Codex, Copilot, or SuperGrok device-code sign-in instead of a mandatory API key. Each bot ge...
The TypeScript framework added a v1 ToolProvider runtime for managing OAuth-backed connections, @mastra/mysql as a first-class storage backend, and a VercelMicroVMSandbox built on ephemeral Firecracker microVMs (GitHub). The MicroVM sandbox is the standout. Per-session isolate...
Vercel Sandbox is now generally available — isolated Linux microVMs for AI agents via Firecracker with active-CPU pricing. Already powering BlackboxAI, Roocode, and v0. Supports clone/fork/resume via snapshotting. Direct competitor to E2B and Modal for the agent runtime layer.
