Sandboxed coding agents for everyone on your team.
Runtime (runtm.com) gives engineering teams control and visibility to enable anyone in their org to use coding agents securely. Eng leaders rolling out coding agents have no way to see what's happening, set boundaries, or safely let non-engineers use them. We provide sandboxed environments, session-level observability, and configurable guardrails so anyone on your team can ship with coding agents without breaking prod. We're live with fast-growing YC scaleups empowering their Engineers, PMs, designers, marketers, and ops to contribute to their codebase or build prod-grade zero-to-one apps.
Runtime provides sandboxed coding agents that run with your company context, integrations, and guardrails, accessible via Slack, Linear, CLI, or browser. It offers multi-agent orchestration, self-host options, and governance across teams.
Installable sandboxed agents that connect to your environments (monorepos, microservices) and run with custom instructions, guardrails, and secrets. Agents can be prompted from familiar tools (Slack, Linear, GitHub, CLI, API) and can execute actions such as generating PRs, deployments, messages, tickets, or reports. Includes mission control for monitoring, cost tracking (per agent/user/team), and governance with spend limits, approvals, and observability (sessions, traces, logs). Supports self-hosting or hosted deployment, with swappable agent types (Claude Code, Codex, Gemini) and extensive integrations (data warehouses, billing, HR, CRM/marketing, support, alerting, engineering). Provides sandboxed compute, pre-warmed environments, and the ability to tag and collaborate on agents across teams, with visibility into all sessions and activities.
Who it’s for: companies and teams seeking to automate work across engineering, product, design, marketing, support, finance, and people ops using sandboxed coding agents with enterprise-grade guardrails and governance
