What Is Perplexity SPACE? The Sandbox Behind Perplexity Computer
How VM isolation, rolling snapshots, and external credential controls keep long-running AI agents fast, persistent, and contained.
TL;DR Perplexity SPACE is the sandbox runtime behind Perplexity Computer. It’s not Perplexity Spaces, the collaboration feature now called Projects. SPACE stands for Sandboxed Platform for Agentic Code Execution, and Perplexity says 100% of Computer sessions run on it. Its architecture uses VM-based isolation, rolling snapshots, external credential controls, and a three-layer system designed for long-running AI agents.
We build AI agents because they can do actual work. Run code. Edit and organize files, a chore we’ve wasted enough human life on since the 1980s. Search databases. Sometimes build the whole thing.
But they can get things wrong.
What Is an AI agent sandbox?
Think of a child doing a messy science experiment. You could hand them the ingredients in your kitchen and ask them to “be careful” (a phrase my kids generally interpret as background noise). Or you could put them in a playroom with a covered floor and keep the bleach locked away.
The second option is a sandbox.
A sandbox gives the agent a choreographed space to work in. You’re the one who sets the controls. Files and sensitive credentials stay protected. If something explodes, metaphorically or otherwise, the blast radius ends at the workshop door.
What Is Perplexity SPACE?
Perplexity SPACE is the sandbox platform that runs agentic workloads for Perplexity Computer. Its acronym explains precisely what it does: Sandboxed Platform for Agentic Code Execution. As of July 15, 2026, all Perplexity Computer sessions run on SPACE.
(Don’t confuse SPACE with Perplexity Spaces, the former name of the collaboration feature now called Projects. Projects organize information for people. SPACE isolates execution for agents. Google still mixes them up.)
