Tips for launching

Hey, I recently helped a similar tool hit $6k ARR in 2 months by nailing user acquisition and marketing. Can help you do the same, just drop me a DM on Twitter.

Hey Morris,
based on the description of your product I'd reach out to designers first.
I remember that we had quite a lot of back and forth between the designer and the developer team during every project to fine tune the UI of the website / app we've been working on.
Based on my experience, most of the developers don't care too much about creating a frontend that completely follows the design created by the designers and that really bugged them. You can highlight this pain point and how your tool can help to resolve this (or at least make the process faster).
So look for UI designers on Twitter, Dribbble, Behance, Linkedin, Facebook groups, subreddits, etc and send them a short case study (eg a 1 minute "long" video) about the benefits of using your tool.
Also, I think https://muz.li/ is really popular (or at least used to be) between designers so you can try to feature your product there to reach a mass of your target audience.
Niche newsletter could be interesting as well, try to find a few that is consumed by your target audience.
