Lidar reads Reddit every day and brings you the people describing, in their own words, the exact problem your product solves. You paste your site, Lidar works out your market and the subreddits worth watching, and from then on you get a short daily list of posts with the reason each one matched and a link straight to it. You read what they wrote and decide who is worth a reply, because Lidar never messages anyone on your behalf. One product is 14 euro a month, with a free trial.
YourTraffic is open-source, cookie-free web analytics. No cookies and no personal data means no consent banner, so you stay GDPR, CCPA and PECR compliant by default. Run unlimited sites on one account, keep your data in your own Postgres, and pull stats through a documented REST API. It also ships a native MCP server, so an AI agent can sign in with OAuth and read your traffic on demand. Self-host it for free under the MIT license or run it in the cloud. One script tag and you are live.
ContactAPI is an open source API for saving contacts. You send a POST with an email and any JSON fields you want, and they get saved as is. The rest is plain CRUD to list, get, update, and delete.
Use a secret key on your backend, or a publishable key in the browser that can only create contacts and is locked to your domains.
It also runs an MCP server, so AI clients like Claude can manage your contacts directly.
