Built for developers and digital agencies who want a clean API-first experience with public REST endpoints, developer docs, and a UI that stays out of your way. Quotes with versioning, project tracking, and client portals included.ers, freelancers, and digital agencies. REST API included.

Create invoices, manage clients, and track payments with an AI Agent, or build your own integrations with our SDK, REST API, and CLI.

  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.

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
