Launch HN: Runtime (YC P26) – Sandboxed coding agents for everyone on a team
Runtime (YC P26) launches sandboxed coding-agent infrastructure that lets non-engineers on a team use tools like Claude Code and Codex without requiring per-session engineering support.
Hey HN, We're Gus and Carlos from Runtime (https://runtm.com). We're building infra that lets your whole team (including non-engineers) ship with Claude Code, Codex, and other agents without engineering having to handhold every session.After Mentum (YC S21) was acquired, I personally shipped 4 full-stack products in 3 months using coding agents. When I tried to roll the same workflow out to the rest of the team, it fell apart: Most PRs were unmergeable slop - Every repo required an engineer doing one-off local setup. - Skills and context lived in one person's head. - There was no safe way for a PM to touch a real codebase without risking a bad deploy or a secrets leak.Carlos comes from building agentic reconciliation systems at Modern Treasury and had a similar experience when letting his support team use devin.We ended up building internal background agent infra but it quickly became a nightmare to mantain and develop.
We built Runtime so you don't have to do this kind of thing.Runtime work like as follows. Engineering defines the context once: system instructions, skills, and scoped integrations installable via CLI, mise, npm, or any package…
