About the launch
EveryApp lets founders and small teams run open source business software and custom apps built by coding agents, inside a Cloudflare account they control. Ben Senescu's Y Combinator Fall 2026 company is launching the self-hosted Gateway, which handles sign-in, databases, permissions, and API keys so Claude Code, Codex, or Cursor can take an internal tool off a laptop and put it online. OpenSEO, an open source alternative to Semrush and Ahrefs, already has more than 25,000 GitHub stars. This launch runs it on the same Gateway as OpenCRM, OpenAnalytics for cookieless web analytics, and OpenMail, an inbox where an agent drafts replies for a person to send. The software is free and open source. Teams pay Cloudflare, starting with the Workers Paid plan, and supply their own keys for search data and models. A prompt or a setup command creates the Gateway on a domain in that Cloudflare account, and each app installs under it. Apps have no public address, and nobody reaches one until they sign in and access is granted. Shared API keys stay on the Gateway. Senescu, previously a senior software engineer at Klaviyo, shipped a bare Gateway in January, then built OpenSEO before opening the platform to this wider set of apps.
