Stripe Projects (Cursor 3) can provision services like Railway, PostHog, and…

Brief

Stripe Projects is a new Cursor 3 feature that provisions services (Railway, PostHog, Vercel) from the CLI and syncs environment variables, e.g. "$ stripe projects add posthog/analytics". Launched as a developer preview on 2026-04-10, it creates accounts, fetches API keys, configures billing, and will expand to many more providers; signups at projects.dev.

Why it matters

Stripe Projects (Cursor 3) can provision services like Railway, PostHog, and Vercel in a single CLI prompt and sync environment variables; example command: "$ stripe projects add posthog/analytics".

Key details

  • The tool will create provider accounts, retrieve API keys, and (as needed) set up billing automatically; Projects launched as a developer preview on 2026-04-10 and is available for registration at projects.dev.
  • Post cites Patrick Collison quoting Andrej Karpathy’s MenuGen workflow to justify the feature: Projects aims to eliminate manual account/configuration steps agents currently require, and Stripe plans to add many new providers over the coming weeks (providers invited to get in touch).

When @karpathy built MenuGen (karpathy.bearblog.dev/vibe-c…), he said:

"Vibe coding menugen was exhilarating and fun escapade as a local demo, but a bit of a painful slog as a deployed, real app. Building a modern app is a bit like assembling IKEA future. There are all these services, docs, API keys, configurations, dev/prod deployments, team and security features, rate limits, pricing tiers."

We've all run into this issue when building with agents: you have to scurry off to establish accounts, clicking things in the browser as though it's the antediluvian days of 2023, in order to unblock its superintelligent progress.

So we decided to build Stripe Projects to help agents instantly provision services from the CLI.

For example, simply run:

$ stripe projects add posthog/analytics

And it'll create a PostHog account, get an API key, and (as needed) set up billing.

Projects is launching today as a developer preview. You can register for access (we'll make it available to everyone soon) at projects.dev. We're also rolling out support for many new providers over the coming weeks. (Get in touch if you'd like to make your service available.)
