The official Slack AI product looks great, but with limited access and add-on pricing, I decided to open-source the version I built. Especially for all the communities on Slack that would have to convert to paid and buy the upgrade to access the official SlackAI product/add-on which is not going to be financially viable in most cases. There's no plan to sell anything, just something I built as a way to learn some new tools that I thought others might get use out of. The repo is a ready-to-run slack app that provides thread summaries and channel overviews on demand using OpenAI (heavy…

It works on top of the open-source workflow engine windmill [1] that you can easily self-host on a tiny server or a large k8s cluster. You will also need pgvector (here hosted on supabase) and of course a GPT4 api key. It showcases an approval step so that you only provide answers you are confident giving to your users, which feels less robotic. All the building blocks are scripts that you can reuse outside of windmill and you could build this in any other workflow engines (although less conveniently). We use it for our own needs on discord [2] and thoughts this was a common need for any…

Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

Hey HN, I'm Hakan, the founder of Colanode (https://github.com/colanode/colanode), an open-source, local-first collaboration app combining the best of Slack-style chats and Notion-style note-taking, fully self-hostable for complete data control. Here's a quick demo: https://www.youtube.com/watch?v=wp1hoSCEArg As a heavy Notion user, I often found it tough to get my teams fully onboard since people naturally gravitate toward chat for quick interactions. Maintaining context between chat apps like Slack and documentation apps like Notion became increasingly…

Hey HN – I built Dock after years of team chat frustrations as a founder. Free forever for teams up to 5. Unlimited search, unlimited history. No "upgrade to see messages older than 90 days" nonsense. Built for teams who work both async and sync/real-time when it matters. runs on SOC 2 infra, compliant, secure and in-transit and at-rest encryption, runs on Cloudflare. Early stage – would love feedback from anyone who's felt the same pain.
