Developer Tools
CLIs, APIs, SDKs, and builder tools from developers who ship for other developers.
Developer Tools on Launchpadly skews practical: libraries, dashboards, observability helpers, auth utilities, and workflow enhancers that engineers can try within minutes.
Technical audiences care about stack fit. Listings that fill in tech_stack and link GitHub tend to earn stronger engagement. Browse related /built-with pages for tools that share your framework.
If you are launching a devtool, write a show-HN-friendly tagline, include a public demo or docs link on your site, and expect blunt feedback in comments — that is a feature of this audience.
