Analysis
The Firecracker-backed, Apache 2.0 platform behind every Computer session is now public. The forward roadmap signals something bigger than execution.
On October 15, 2026, Perplexity released its execution sandbox to the public. The SPACE repository — Sandboxed Platform for Agentic Code Execution, written in Rust — carries an Apache 2.0 license, 820 stars as of October 16 (770 in the first 24 hours per the announcement), and the production record of powering every Perplexity Computer agent session since July 2026.
The technical foundation is Firecracker microVMs — the same AWS-originated virtual machine monitor underpinning E2B, DigitalOcean Agent Droplets, and the sandbox forking pattern our earlier coverage identified as one of two load-bearing pillars of agent security. Each SPACE agent task runs in its own microVM with credentials and outbound traffic controlled from outside the VM. The performance numbers are notable: median sandbox spin-up of approximately 60 milliseconds, with support for pause/resume and rolling snapshots persisting up to one week. Perplexity reports zero escapes across approximately 118 adversarial test attempts.
The repository ships with an E2B Compatibility Wrapper supporting the E2B Python SDK, documented in the SPACE documentation. Cloud partners CoreWeave, Akamai, and Crusoe are working to offer SPACE to their own customers.
The real forward signal is not the sandbox itself but what Perplexity says comes next. Secondary coverage…
