Introducing EveryApp (YC F26). Our mission: make every app open source. We started with OpenSEO (24k GitHub stars). Now we're doing it for every app your business runs on. Star the project, try an app, or build your own 🧵

If you just want to get started or give it a star ⭐, here’s the repo:

Your agent can build an internal tool in an afternoon, but how do you put it on the internet? Hosting, database, sign-in, permissions, API keys and backups are all still hard. So most of it never leaves localhost.

EveryApp handles all of that. One command sets up a Gateway in your Cloudflare account, and your team signs in once to use every app.

Building apps is simple because the patterns are pre-defined. No need to choose a web framework, decide on infrastructure, or expose an MCP. Your agent builds it, and one deploy puts it behind your team's sign-in.

Each app is available to your agent through a single EveryApp MCP connection.

Apps have no public address on the internet, so every request goes through the Gateway. It holds your API keys and secrets too, so apps never see them.

Everything is serverless. Idle apps cost $0. One $5/month Cloudflare plan can host hundreds. No per-seat or arbitrary pricing. Pay only for what you use.

OpenSEO was first. OpenCRM and OpenAnalytics are next. What should we build after that? 👇

just a slightly expanded scope. from SEO to... everything? 😂

hahaha we actually reduced scope to just SEO temporarily

Touché

This is awesome, would love to chat and collab on this mission Ben! Can you open DM

100% just DMed you

Getting an internal tool off localhost is a much more interesting problem than generating another demo. With several apps behind one team sign-in, how do you handle permissions—can someone use one app without giving its agent access to data from the others?

LETS GOOOOOOOOOOOOO

Why would people make apps if they can’t sell the apps? The future is a bit dumb!

We're just getting started 😏

appreciate you 🙌

Open source changes the buying decision completely. You are not locked into a vendor roadmap, you can read the code and shape it. Starting with one proven app, then expanding, is a smart way to build trust.

Congrats!
