Suborbital

Suborbital was a developer-tools company building a WebAssembly-based extensibility platform: the Suborbital Extension Engine (SE2, formerly Suborbital Compute), a hosted service for running sandboxed third-party plugins; E2 Core / Reactr, a function scheduler for Go and WebAssembly; Sat, a tiny fast Wasm edge-compute server; Grav, an embedded decentralized message bus; and the subo CLI for building Wasm plugins and scaffolding projects. Suborbital was acquired by F5 in 2023 and the hosted product was subsequently wound down; the suborbital.dev domain has since been repurposed as an unrelated content blog. The first-party open-source client libraries (npm @suborbital/*, the se2-go Go client, and the subo CLI) and the 32-repo GitHub organization remain publicly available.

Suborbital is profiled on the APIs.io network. Tagged areas include Company, Developer Tools, WebAssembly, Edge Compute, and Serverless.

Suborbital’s developer surface includes CLI and 6 more developer resources.
