   SuprSend▲406

   We as developers, build and maintain many services in code, one of them being notification service. In the last 5-7 years, API-to-user communications have exploded across SMS, email, chat apps, mobile, and web push. As a consequence, notification service handling them has become quite complex. Developers spend time building integrations with multiple providers, create templates for each channel, managing scheduling and routing based on preferences, maintaining queues to deliver notifications on time while managing scale. Besides, product teams have poor visibility on notifications as…

   Nous – Open-Source Agent Framework with Autonomous, SWE Agents, WebUI▲155

   Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse&#x2F;Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

    143.dev – we open-sourced our internal coding-agent infrastructure▲13

    We just open-sourced the internal system we built at Assembled for running coding agents as a team. Coding agents worked well for individual engineers, but the surrounding workflow was a bit of a mess. We generally found that many engineers had different MCP connections and context for their agents, personal automations running that other people couldn’t access, and very little introspection for what a human’s input into the coding agent looked like. So we built an internal system that converted coding agents into shared team infrastructure. The system runs Codex, Claude Code, OpenCode, and…
