Why it mattersA small team can swap a paid SaaS for an open-source copy without buying infrastructure. The gateway sits in front of every app, with one sign-in.
A business running on ten different SaaS tools pays ten vendors. It holds ten passwords. It feeds ten different accounts with its own data.
EveryApp posted its YC launch today, naming the Fall 2026 Y Combinator batch. Its vote count on the YC launches page sits at 14 at the time of writing. The company's pitch, in its own words: EveryApp is building open-source alternatives to every SaaS. The platform hosts these apps, plus any custom apps the user's agent builds, in the user's own Cloudflare account.
What the company says it does
The YC launch names two tasks the platform is meant to make easy. The first is hosting open-source apps. The second is hosting custom apps that someone has built with a coding agent. A team reaches both through the EveryApp Gateway. Every request passes through the gateway, so an app has no public address. The gateway holds the API keys. Each app asks the gateway for access when it needs to call out. No app ever holds the keys itself.
The platform is self-hosted today. The company says the setup takes a few minutes for anyone comfortable with a coding agent. A managed version is on the way, starting at $10 a month and scaling with usage.
The infrastructure cost it names
EveryApp says the apps are serverless, running in the user's own Cloudflare account. An app costs nothing when it is not used. The paid Cloudflare plan at $5 a month is enough to host hundreds of apps, by EveryApp's own figure. Every app added through EveryApp is reachable through the EveryApp MCP Gateway. That is how a coding agent calls it as a tool.
The founder and the proof point
The YC launch names Ben Senescu as the person behind the company. His bio there names two past roles. He was a senior software engineer at Klaviyo. He was then a founding engineer at a company building agents for compliance. The founder also names OpenSEO. OpenSEO is EveryApp's open-source alternative to Semrush and Ahrefs. The company built it to prove the model would work. The GitHub repo for OpenSEO carries 25,098 stars at the time of writing.
The EveryApp platform repo at every-app/every-app on GitHub is smaller. It carries 88 stars under the MIT license, and was created about a year ago. The company's own list of EveryApp apps includes an open CRM. There is a web analytics app with no cookies or stored IP addresses. There is a team inbox with an AI agent that reads, drafts and sends email on a user's domain. Each sits at one or two GitHub stars today.
The pitch, in the founder's words
The founder writes two reasons for building it. Companies are not getting the full value of coding agents. Putting a web app behind one secure sign-in is still too much work. And ninety-nine percent of businesses need the same set of basic tools. The founder's position is that those tools should be rebuilt. Each company's own agent should drive them. They should be hosted in that company's own account. They should stay open to change when they do not fit.
