Launch HN: Runtime (YC P26) – Sandboxed coding agents for everyone on a team
Source: Hacker News
The runtime for all your team’s agents
Sandboxed coding agents with your company’s context, integrations, and guardrails.
Environments with every tool your team uses
Connect all of your company’s environments—from monorepos to microservices. Install any CLI, API, service, or MCP server, layer in custom instructions and skills, then set guardrails and secrets. Snapshot once so every session boots in seconds.
Install from mise, npm, brew, or GitHub.
Datadog 
Salesforce 
Stripe 
NetSuite + anything else
Specialized agents your team can tag wherever they work
Build an alert inspector for incidents, a sales prospector for revenue, or a support triager for your inbox. Each runs investigations, ships PRs, drafts replies, and posts findings without anyone asking. Tag them from Slack, Linear, GitHub, Jira, or any tool your team already uses.

Let anyone on your team work alongside agents
Anyone can prompt an agent and watch it work—engineers, support staff, salespeople. Hand off mid‑session, collaborate in real time, and ship the result however your team needs: a PR, a deploy, a message, a ticket, or a report.
See and govern every agent in your company
Live visibility into every session: tool calls, chain‑of‑thought, file changes. Track cost per agent, per user, per team. Spend limits, allowlists, and approval gates are baked in.
Use it your way
Browser, terminal, or API.
Every layer your team’s agents need
Built‑in, customizable, ready to ship.
Sandboxes, orchestration, guardrails, observability, integrations — Runtime handles the agent infrastructure your team would otherwise spend months building from scratch.
A coding agent for every team
Each team gets a sandboxed agent with the data, integrations, and guardrails they need.
Self‑hostable – Deploy Runtime on your own infrastructure with your own cloud, models, and secrets. Extend it with custom skills and integrations.

FAQ
Who is Runtime for?
Runtime is for any company that wants every function to ship work with a coding agent, not just engineering. Platform teams use it to roll out agents safely, while product, design, marketing, support, finance, and people teams use the same sandbox to automate work they already own.
How do agents work inside Slack? Do we always have to tag them?
You can tag them, or let them work proactively. Each team gets its own sandboxed agent in Slack with a name you choose (e.g., @runtime‑finance, @runtime‑support, @ada). Mention it with a question or task, or point it at a channel so it picks up new messages automatically. It replies in a thread with the result, source rows, cost, and an “Open Session” button for deeper inspection.
What integrations come out of the box?
Runtime ships with first‑class connectors for the systems most teams already run, including:
- Data warehouses: Snowflake, BigQuery, Redshift
- Billing: Stripe, NetSuite, QuickBooks
- HR: Rippling, Gusto, Workday, Deel
- CRM & marketing: HubSpot, Segment, GA4
- Support: Zendesk, Intercom
- Alerting: PagerDuty, Sentry, Datadog
- Engineering: GitHub, Linear, Notion
You can also bring any tool with an API key; agents reach it via CLI, MCP server, SDK, or REST API just like an engineer would.
Does an agent ever touch our raw production data?
No. Agents work against sandboxes that mirror or sample your data under policies you set, including PII redaction and row‑level scopes. Production writes happen only through reviewed actions or pull requests, so the agent never edits live systems on its own.
Can I self‑host Runtime?
Yes. Run Runtime fully inside your own cloud with your own models, sandboxes, and storage, or use the hosted version. Policies and audit logs follow your team across both deployments.
