Been building a open-source technical interview platform. Trying to keep the existing ideas of async coding assessments + live programming interviews, but want to add features for the new interview formats I see of take-home projects + AI coding agent interviews

Building Pasture (https://www.usepasture.com)
Pasture takes each signup, enriches it (title, company size, funding, tech stack, and more), and scores it 0-100 against your ICP. Alerts go to Slack with full context. You can also track which channels bring quality vs. junk over time, which has been the most useful part so far.

Hey!
I built Pasture to help marketing-led and product-led companies figure out their best growth channels and see if the signups they are driving match their desired ICP!
Would love any feedback

Show HN: No BS site to view government salary data
I built a simple site that uses public data from the U.S. Bureau of Labor Statistics to better visualize the salary data. The only bad thing is that some states dont have data for specific occupations, and some salary data is just marked as being >$229,000 instead of the exact number.

Well I am not a fan of RapidAPI for a couple reasons, firstly them taking such a big cut of an API provider's business and secondly their marketplace feels kinda spammy and low quality.
I am trying to build so that there is little vendor lock-in (you can export your users to other auth providers, billing is integrated directly into your stripe account, etc) so that you still have the choice to migrate if you ever feel unhappy with the service
