Sick of running random cron jobs, I built a small Keepalive for my FaaS

In plain words

Keepalive is a tool designed to prevent Function-as-a-Service (FaaS) applications from going dormant due to inactivity. It helps developers maintain consistent performance by sending periodic requests to keep their serverless functions active and responsive. The tool addresses a common challenge in FaaS environments where functions may experience slowdowns after periods of inactivity. It's intended for developers who rely on serverless infrastructure and want to avoid the cold-start performance penalties that come with idle functions.

  Keep – GitHub Actions for your monitoring tools2023 · github.com · ▲181

  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…

  Keep – Open-source alerting CLI2023 · github.com · ▲65

  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,…

  Ayder – HTTP-native durable event log written in C (curl as client)Jan 2026 · github.com · ▲56

  Hi HN, I built Ayder — a single-binary, HTTP-native durable event log written in C. The wedge is simple: curl is the client (no JVM, no ZooKeeper, no thick client libs). There’s a 2-minute demo that starts with an unclean SIGKILL, then restarts and verifies offsets + data are still there. Numbers (3-node Raft, real network, sync-majority writes, 64B payload): ~50K msg/s sustained (wrk2 @ 50K req/s), client P99 ~3.46ms. Crash recovery after SIGKILL is ~40–50s with ~8M offsets. Repo link has the video, benchmarks, and quick start. I’m looking for a few early design partners (any…

  Keep – Create production alerts from plain English2023 · github.com · ▲46

  Hi Hacker News! Shahar and Tal from Keep Here. We were tired of creating alerts for our applications, so we've built an open-source GitHub Bot that lets you write application alerts using plain English. The code is open-sourced: https://github.com/keephq/keep so you can review it yourself. Every developer and DevOps professional is familiar with the fact that in order to ensure your application works in production, you need to access your observability tool's user interface (such as Grafana, Datadog, New Relic, etc.) and carefully determine how to create alerts that…
