From the sources

Twenty is a modern, open-source CRM alternative to Salesforce—fully customizable, affordable, and powered by the community.

The #1 Open Source CRM for modern teams. Modular, scalable, and built to fit your business.

Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Scaffold a launch-ops CRM in my workspace with rockets, launches, payloads, customers, and launch sites, with relevant actions for each. Proprietary languages, slow deployment cycles, and "black box" logic. It's fragile. V1 ships quickly, but maintaining and making changes is a long term burden. Compose your CRM and internal apps with a single extensibility toolkit. W3villa used Twenty as a production-grade framework for the data model, permissions, authentication, and workflow engine they would otherwise have rebuilt themselves. Alternative…from twenty.com

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

  Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  Workout.cool – Open-source fitness coaching platform▲827

  I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
