Show HN: 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 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.

|
| - I too have tried to think of how plugins could be "full-

| seeing in your repo the code that handles the FE sandboxing? (I
| could be totally looking in the wrong place)
|
| - I looked into using wasm "containers" as well- does your
| architecture have a scalable way to optimize "cold boot" of a
| container for near-instant run/render?
|
| Again, cool project and good luck! I think there's so much room
| for innovation in this area of making micro-functionality truly
| portable & composable!
| born-jre wrote:
| thanks
|
| yeah making core framework in fast low level language and
| making scripting/embed language on top is such underexplored
| area i think.
|
| i have removed suborigin bashed frontend sandbox for now,
| inline iframe is just faster to iterate, i will bring back
| suborigin later. iframe related code would here.
|
| https://github.com/temphia/temphia/blob/main/code/frontend/l.
| .. https://github.com/temphia/temphia/blob/main/code/frontend
| /e...
|
| suborigin code is also same but template part would be in go
| template and you will need to setup (<wildcard>.myapp.com)
| domain name.
|
| no i donot do use any wasm runtime snapshoting, i do cache
| the instance once they are run though so yeah first one will
| have latency.
|
| i will try to post some demo/examples of app running later

| kc10 wrote:

|
| RudderStack is AGPL while cptn is MIT.

| I think there are a number of platforms for building workflows
| and integrations today. Some of the platforms serving specific
| niche (e.g. RudderStack chose to serve CDP, airplane for
| building internal dev tools). But in the end all of them act on
| a trigger to transform inbound event data and send it to a
| destination end point.
|
| Windmill looks cool with support for multiple languages, no-
| code editor and all the OOTB integrations.
|
| cptn is still evolving - it needs to have more integrations, UX
| flows need to be improved, it has to get better from Ops
| perspective.
