Cptn.io – open-source integration platform
Hi, I am Krishna Thota. I am building an open source integration and data platform(https://cptn.io). The product is MIT licensed and the repo is at https://github.com/cptn-io/el-cptn. I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to…
In plain words
Cptn.io is an open-source integration and data platform licensed under MIT that helps developers build and manage data pipelines and integrations. It addresses challenges with cloud functions and message queues by providing built-in monitoring, retry mechanisms, and error handling to reduce manual intervention and unpredictable costs. The platform is designed for developers who need reliable integration workflows without the operational overhead of managing failures, cold starts, and infrastructure expenses.

In the maker’s words, at launch
Hi, I am Krishna Thota. I am building an open source integration and data platform(https://cptn.io). The product is MIT licensed and the repo is at https://github.com/cptn-io/el-cptn. I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to monitor logs for failures, build retry mechanisms or manually process failed events, keep instances running to prevent cold start timeouts. It can also get expensive with charges for MQs, server time for running cloud functions etc and costs can be unpredictable. I thought of building a platform where I can build integrations quickly, have the ability to look at incoming/outgoing events, look at logs, retry any failed events etc. And finally, predictable costs for running the infrastructure. cptn.io provides all these capabilities and more. You can build pipelines to integrate with any cloud services, send data from your backend to data warehouses, listen to web hook events etc. The platform can be integrated into any stack by sending events to HTTP end points. Instead of trying to build a business first or launch an open source product under restrictive licenses, the platform will be available under MIT license so any user or customer can use it. There is no ee folder or complex dual licensing and I am also committing to releasing SSO under MIT. The plan is to offer a managed service in the cloud at a later time, accept sponsors for prioritizing features for enterprise customers and charge for enterprise support. It should take less than 5 minutes to get the platform running on your machine. Welcome any feedback, feature requests, PRs and bug reports.
