Horizon is the right pick for developers who want a self-hosted, community-curated news feed with AI scoring and bilingual briefings.

About Horizon
Horizon is an open-source, self-hosted news aggregator and summarizer that gives you a feed you can filter, audit, and control. It fetches articles from RSS, Hacker News, and other source types, scores each item on a 0-10 scale, and distills top stories into a daily bilingual (English & Chinese) briefing. Community curation is central: 367+ people help shape the feed, and 84 sources are curated. You configure everything via a .env file for secrets, a JSON file for runtime settings, and processing profiles for analysis prompts. The stack is built for concurrency using asyncio.gather, and it exposes a REST API for sources, votes, and search. Horizon is positioned as an 'information source marketplace' for the Horizon ecosystem, using real usage data for discovery. It's not a turnkey product—you need technical comfort—but you get full visibility and control.
Behind the Verdict
Horizon stands out because it combines AI scoring with human curation, giving you transparency that closed aggregators like Feedly don't offer. You can see exactly what goes into your feed: sources are community-voted, and you configure everything from a JSON file and .env. The use of asyncio.gather means fetching is fast, and the REST API opens integration possibilities. For developers, this is a playground: you can extend scrapers, tweak processing profiles, and build your own dashboard. However, it's a developer tool, not a consumer product. The setup involves editing config files, and there's no mobile app or push notifications. Non-technical users will struggle. If you value control and are comfortable with self-hosting, Horizon is a gem. If you just want news without effort, stick with a hosted service.
