24 alternatives to ServiceBeard

ServiceBeard is an open-source sync tool which polls your IMAP server for new mail and creates new issues on your repo/project, or posts comments if it's a reply to an existing thread. In the other direction, any comments on the issue triggers an outgoing email to the customer (using your SMTP server). The obvious use-case is setting up a service desk using existing infrastructure, but I'm curious to see what other use-cases come up. I'm Joram, the solo developer who built ServiceBeard. My team was managing a shared mailbox by using coloured labels and read/unread statuses just to…

    Hello HN! I wanted to share something we at Good Enough (https://goodenough.us) built over the past year: Jelly! https://letsjelly.com Jelly is a simpler shared inbox for small teams (like us) to answer team email. We had just been sharing a login to Fastmail previously, but as email started getting busier, that really started to stink as a solution — no one knew who was going to answer what, if someone else saw an email or not, etc etc. And a Google Group would prove to be worse, as replies too easily got lost to personal inboxes if someone accidentally didn’t “Reply…

    Hey HN! Been a while.. last post for reference in 2020: https://news.ycombinator.com/item?id=22985055. Moved city, job and had two children since then which is wild :) Been working away shifting Kanmail over to a Go backend (using the excellent wails) and rewriting the frontend in TypeScript. This "new" v2 is much quicker, overcomes a bunch of old limitations (no age limit on paginating folders) and finally gets a working Linux AppImage (*my Linux test setup is somewhat limited and I expect there's plenty of edge cases here - hit me up if you have issues). Anyway, would love…
