24 alternatives to I made a tool to receive alerts when answers change

Hi HN, I've created a tool called Alertfor that scours the open web to find the most relevant and up-to-date answers for complex questions. You can set up alerts to receive continuous updates whenever there are changes or new information becomes available for a given question. I used an agent framework (Autogen + Sibyl) to collect and answer questions, and I schedule a Celery job to run the same query continuously every six hours. I would love to hear your feedback, suggestions, or anything else you’d like to say. Note: I'm submitting this for a second time; I'm not sure if this is against…

    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…

    Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN (https://news.ycombinator.com/item?id=34806482) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools…

    Hi Hacker News! Shahar and Tal from Keep here. We're thrilled to announce that we're open-sourcing our alerting CLI tool, Keep (https://github.com/keephq/keep). Designed by developers for developers, Keep streamlines and simplifies alerting, making it a first-class citizen within the development process. Think of Keep as Prometheus Alertmanager but for all observability tools, with a simple and intuitive (GitHub actions-like) syntax. We believe that alerting has historically been neglected in existing monitoring platforms, leading to subpar alerting practices. With Keep,…
