FastScheduler – Decorator-first Python task scheduler, async support
Hi! I've built this because I kept reaching for Celery for simple scheduled tasks and it felt like overkill. I just needed "run this function every hour" or "daily at 9am", not distributed workers. So it's decorators for scheduling (@scheduler.every(5).minutes, @scheduler.daily.at("09:00")), state saves to JSON so jobs survive restarts, and there's an optional FastAPI dashboard if you want to see what's running. No Redis, no message broker, runs in-process with your app. Trade-off is it's single process only — if you need distributed workers, stick with Celery.

In plain words
FastScheduler is a Python task scheduler designed for developers who need simple, lightweight job scheduling without the complexity of distributed systems like Celery. It uses decorators to define recurring tasks at intervals or specific times, persists job state to JSON for crash recovery, and includes an optional FastAPI dashboard for monitoring. The scheduler runs in-process with your application, requiring no external message broker or Redis, making it ideal for single-process applications with straightforward scheduling needs.

Async tasks in 350 lines of C2024 · github.com · ▲146Tasks are a primitive for asynchronous programming and an alternative to working with threads directly. Instead of creating a thread, performing work, then waiting on it using synchronization primitives, you only define a unit of work and let a scheduler decide when and where to execute it. The threads that the scheduler uses are created once and reused for many tasks throughout the program's lifetime. In most cases, creating and executing a task requires not even a single syscall and is a significantly faster operation than creating a thread, resulting in lower latency. Furthermore, tasks…

What it does: It's a macOS app that schedules your local Claude Code to run on any schedule you want - daily, weekly, or custom cron expressions. My use case: Every night at 11pm, it automatically summarizes my Obsidian daily notes. But, it can schedule any Claude task - code reviews, data processing, report generation, web research, file organization, etc... Technical details: - Native macOS app (Electron + React) - Uses launchd for scheduling (proper macOS…

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
