So excited to launch @stripe Projects: Let your agent autonomously build and deploy an app end-to-end. Check it out at projects.dev

We shipped Stripe Projects recently and developer advocate Ben Smith set out to see what it was like to actually build with it. The shift "I have accounts with tools" ➡️ "I have a project that can assemble itself." A small change until coding agents become the primary builders. Modular, headless infra means the agent just plugs in what it needs. See Ben’s full breakdown on the blog: stripe.dev/blog/what-it-feel…

getting few DMs on how/if this works: yup, one ‘import’ command *literally* creates new accounts or links to all the providers in the stack, provisions them in batch, and returns the full set of keys & env vars you need. wild scenes

C. Stack Share You can now share your entire stack with anyone. $ stripe projects share Send the URL, and they run: stripe projects import <URL> stripe projects init --from <URL> projects.dev/s/v1:vercel~pro…

We lifted the waitlist for projects.dev yesterday!

Stripe's @collision says Stripe Projects gives agents the ability to buy what they need to orchestrate your vibecoding projects end-to-end: "You guys have probably had the experience of when you're vibecoding away, you are the adult that needs to reach for things on the high shelves for [your agent]." "It's much better at writing code than you, it's able to architect an application for you. So what do you need to do? You need to go sign up for an API key." "[With Stripe Projects], you are able to agentically do stuff in the wider world. You can hook up your Codex in Stripe Projects, and if you want to deploy a website, it can go sign up for Vercel for you, and it can pay for it." So now, what was previously a multi-step process where [the agent] could kind of do some version — it could orchestrate Vercel but not sign up for it — now it can pay for Vercel, it can pay for Cloudflare, it can pay for BrowserBase if you want to do headless web browsing." "We think the agents are going to get so much more powerful, because we're giving them the ability to actually go buy what they need in the wider world, and then it can do way more end-to-end."

You can now browse the growing list of providers with agentic provisioning via Stripe Projects. "Claude, integrate PostHog. Make no mistakes." works straight from the CLI, including creating an account and API keys for you. projects.dev/providers

Big moment @jeff_weinstein. Zero-human companies being build autonomously using projects.dev to spin up all the infra that it needs programatically. What a time to be alive! No more messing around! s/o to @dotta too!
Honestly @FactoryAI is undefeated. So so so underrated. Bravo @matanSF & @EnoReyes. Hey @jeff_weinstein, stripe.dev now integrated into our company builder tool so that every company built gets resources auto-provisioned for them. So good.

Stripe processed $1.9 trillion in payment volume last year. They just built a CLI that lets AI agents provision and pay for every service in your stack with one command. Read that again. Karpathy writes a blog post about how painful it is to wire up services manually. Patrick Collison quotes it and announces the fix. The fix happens to route every agent's billing through Stripe. Vercel, Supabase, Neon, PlanetScale, PostHog, Clerk, Railway, Turso, Chroma, RunloopAI. All provisioned from the terminal. All billed through Stripe. One payment method stored once, shared across every provider via tokenized credentials. This is the tollbooth strategy executed at infrastructure level. Stripe already handles payments for ChatGPT, Claude, Cursor, Replit, Lovable, Midjourney, and Vercel. Now they're the layer that lets those tools' agents set up the services underneath them too. Every AI coding agent that spins up a database, connects auth, or adds analytics is doing it through Stripe's pipes. The timing tells you everything. Stripe's valuation jumped 74% in one year to $159 billion. Their Revenue suite (Billing, Invoicing, Tax) is on track for $1 billion ARR. 25% of all Delaware corporations are already created through Stripe Atlas. And the new bet is that agents will provision more software, faster, than any human team ever did, and every transaction flows through one chokepoint. The company that solved "accept payments on the internet" just solved "let robots buy software on the internet." The second market is going to be bigger than the first.
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.) projects.dev

for any builders glued to their laptop this beautiful sunday: i’m looking for another handful of beta testers to try a new, somewhat experimental command line tool and give us (critical, detailed) feedback. reach out for a sneak peek =>
🚧 looking for 3 developers who like to try new tools and give (critical) feedback—this weekend... we have a new cmd line tool for those building new apps. if you're willing to write up your thoughts or send a video feedback walking through it, dm or email jweinstein at stripe.

We just announced Stripe Scripts—one of the most powerful primitives we’ve ever shipped, starting with Billing. In a few lines of code you can now change *how* Stripe works. And we’ll host and run *your* code for you.

Stripe Billing (our product for handling subscriptions and recurring payments, usage-based billing, discounts, invoices, per-seat pricing, etc.) is now a pretty large and fast-growing business. (Used by Atlassian, OpenAI, Notion, Anthropic, Intercom, and ~300k other businesses.) While we started (as usual) building for startups, Gartner just deemed Billing a category leader for enterprises: stripe.com/newsroom/news/str…. There is now a large and quickly-growing pipeline of public companies adopting Billing. Even though large companies are typically most lucrative, I'm very bullish on products that target startups first. (1) Startups are discerning and won't put up with legacy/arcane technology. (2) Some become large (so you incrementally grow into the enterprise with them). (3) Maybe most importantly, the startups themselves help inculcate the right internal mindset. Dennis Whyte (of MIT's fusion program) has a "faster, cheaper, sooner" motto. Building for startups effectively forces you to adopt that approach in your own product development.
