Tembo
Cloud platform that runs any coding agent in shareable sandboxed environments.
Tembo runs AI coding agents (Claude Code, Codex, Cursor, Amp, OpenCode, Pi and others) in isolated cloud environments with source code, terminal, files and a live desktop, turning issues and alerts from Sentry, Linear and Jira into pull requests, including coordinated multi-repo changes. Tembo Previews spin up frontends, APIs and databases behind tunnel links; agents reach databases and team tools via MCP. It offers per-task model routing, scheduled tasks, webhooks, a public API and TypeScript SDK, plus SSO, RBAC, audit trails and self-hosted/VPC deployment.

Elastic sandboxes for running AI-generated code.
Daytona provides secure, OCI-compatible sandbox 'computers' that spin up in under 90ms — with snapshots for persistent agent state. In 2026 it moved core development to a private codebase while continuing to run as a commercial platform.
