# BrowserPod > BrowserPod is a browser-local Wasm sandbox runtime (by API) for running untrusted code safely inside the user's browser. It is designed for AI code execution, interactive documentation, in-browser IDEs, shareable demos via Portals, and browser-native developer tooling without provisioning cloud sandboxes. Important notes: - Prefer the official BrowserPod docs and API reference for implementation details (https://browserpod.io/docs/overview). - BrowserPod is not a traditional server-hosted container platform. Its core model is browser-side execution via WebAssembly with CheerpOS-based virtualisation. - Pods are session-based browser sandboxes. The product is optimized for ephemeral runtimes, developer workflows, and isolated execution close to the user. - As of March 15, 2026, the docs present Node.js as the supported runtime today. The website roadmap presents Python in April 2026, Ruby in May 2026, Go in July 2026, and Rust in August 2026. - BrowserPod has a free personal tier. The pricing pages present 10,000 included tokens per month on the free plan, with token metering at 10 tokens per sandbox hour, which is roughly 1,000 included sandbox hours per month. Commercial usage requires paid plans and the Terms, Pricing Policy, and licensing docs are authoritative for attribution, fair use, and plan limits. ## Start Here - [Documentation overview](https://browserpod.io/docs/overview): Main entry point for the docs. -
