Show HN: Cptn.io – open-source integration platform

#1
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.

Is this an open source Segment Analytics competitor? I liked the idea of segment, but the pricing jumped way up after the free tier and I had to remove it

Technically the product can be used as CDP platform if a client library is capable of sending tracking events to the Source URL and you just want to pipe them to your buckets/data warehouses.

So is this like an Open Source Zapier or at least with similar ambitions if not quite there yet ?

Yes, over time with contributions from community the app library will grow and pipelines can be built with ready to use apps.

For complex cases or specialized integrations, you can use any npm library to build your flow.

You can integrate into your stack with HTTP API and we can build SDKs for popular languages so it's just a function call to send the events.

How does this compare to, say, RudderStack?

It can work similar to RudderStack if we build a JS library that can send tracking events into the platform. But I think Rudderstack has more features around ETL and Reverse ETL which do not exist today in cptn.

RudderStack is AGPL while cptn is MIT.
