Hi there! Co-founder of Caido (https://caido.io) here.

Glad to see more competition in the space, we also went the route of using an API (built in Rust). We decided to focus only on a web UI in vue.js I will look how you are storing data and all, we went the sqlite way to save on RAM.

Looks like we are both going after Burp, it's not going to be an easy ride for sure. What we found is it is very hard to make people in enterprise switch and the 100$/y pricing really isn't enough to build a serious business without enterprise clients at a higher price point.

Anyway, best of luck!

Hi!

Yeah, it seems like we've identified similar problems and addressed them in reasonably similar ways. Likewise, I've went with SQLite as the project file format, with the files being compressed when saving so that users can transfer/share the project files easier.

Thanks for the insight on the pricing. I've been working under the assumption that if a few people on my team at work wanted to spend $100US each on tools, that they think would improve their productivity, it'd be a no-brainer and easy to justify.

I definitely think that more competition in this space is good for the industry as a whole, and likewise wish you the best of luck!

We don't currently compress data but we might at some point. We found that the most significant speed increase is by splitting the data into multiple files. Otherwise it becomes very slow at 10-20GB range.

Yes and your 400$ plan is a good idea. But we did the math at 100$ (Port Swigger financial records are public) and it is not easy to make them work as a full time gig. And it's not really possible to get funded just for that market, it would need to 10x to be VC viable.

If you ever want to talk further, do shot me an email (emile [@] caido.io).

Hi, I took some time to use Caido. I really like it, especially the ability to switch between projects. I also thought the UX that introduces users to the application was well-done. Tbf, I have years of experience with Burp, but I think anyone would have been able to follow along. Nice, clean UI and installation was breezy. Great job! Looking forward to seeing how this project develops, and I wish you success in your competition with the incumbent.

This may be a really broad question, but would you mind touching on why you developed this in Rust? Is that the reason why this application feels snappier than Burp (JVM), or is it just less taxing on system resources? Please feel free to tl;dr it if that's easier :)

Also, the coolest looking feature is the AI assistant undoubtedly -- is there any chance that customers can BYOT in the future and supply a personal OpenAI API token for example?

Thanks for the review and kind words. This was really one of the core goal to make it super accessible.

We developed it in Rust because we wanted to create a client/server architecture that you can deploy everywhere (Caido runs even on a rapsberry pi). We worked a lot on the frontend to make it snappy too, so its a combination of both.

Yes for sure, there is a privacy concern too with us forwarding request. It is in the issues of https://github.com/caido/caido.

Interesting, wasn't aware that there were Burp alternatives being worked on. I'm going to play with both of these to see how they compare. Thanks to both you and OP for sharing!
