OpenInt (YC W23) Open-Source iPaaS to Ship Product Integrations Quickly
Hi HN, we’re the team behind OpenInt (https://openint.dev). We started building a unified API for crypto payments at Map3 (YC W23), but scaling dozens of custom integrations for each customer was painful and repetitive. We learned how valuable it would be to have a platform that lets any team quickly stand up private and fully controlled integrations without reinventing the wheel each time. OpenInt is an open-source integration platform as a service (iPaaS) that helps you ship product integrations in hours, not weeks. We just participated Mega Launch Week (Dec 2–6…
In plain words
OpenInt is an open-source integration platform as a service that enables development teams to build and deploy product integrations in hours rather than weeks. It provides a unified foundation for creating private, fully controlled integrations without duplicating work across customers. The platform includes a pre-built integrations page, automated data synchronization capabilities, and a unified API, designed to reduce the repetitive work typically involved in scaling custom integrations.

In the maker’s words, at launch
Hi HN, we’re the team behind OpenInt (https://openint.dev). We started building a unified API for crypto payments at Map3 (YC W23), but scaling dozens of custom integrations for each customer was painful and repetitive. We learned how valuable it would be to have a platform that lets any team quickly stand up private and fully controlled integrations without reinventing the wheel each time. OpenInt is an open-source integration platform as a service (iPaaS) that helps you ship product integrations in hours, not weeks. We just participated Mega Launch Week (Dec 2–6 https://launchweek.dev/lw/MEGA) and introduced (https://openint.dev/launch-week): - Dec 2: OpenInt – Open-source iPaaS platform. - Dec 3: @OpenInt/Connect – Fully featured integrations page for your app. - Dec 4: OpenInt Sync – Automated data syncs straight into your database. - Dec 5: OpenSDKs – Typesafe SDKs with an auth proxy for any API. - Dec 6: Orchestrate & Our Partner Program – Unified aggregator orchestration plus our partner ecosystem (initial ones are also other OSS YC companies). We think the above makes OpenInt the LAST integration you’ll ever need. If there’s any connector missing, tell us about it, and either we or one of our partners will write it for you in 72h for $1000. We went through Y Combinator W23 and are now fully committed to building an open ecosystem. The stack is mostly TypeScript on Cloudflare Workers with Postgres for storage—designed to be easy to run and scale on your own infra. Long term, we want to see open-source AI agents assist developers in auto-generating and maintaining integrations and SDKs, collaborating directly within the repo. Here’s[1] a 1-minute demo video to show how fast you can launch an integration. Check out the integrations list, star our GitHub repos (OpenInt[2] | OpenSDKs[3]), or hop into our Slack community (signup via https://openint.dev) to say hi. [1]: https://www.youtube.com/watch?v=FpG7otZZhRw [2]: https://github.com/openintegrations/openint [3]: https://github.com/openintegrations/openSDKs We're not quite ready for a full Launch HN yet (hence the Show!), but we’d love your feedback—tell us what’s missing, where we can improve, or what you’d like to build with OpenInt!
