It supports RSS feeds, and for anything else you can write a simple JS plugin to fetch any API. There's a community plugin directory at https://glanceway.app/sources, and a skill you can add to Claude to have it generate plugins for you (https://github.com/glanceway/glanceway-sources/blob/master/g...).
Your aggregated feeds are exposed via a REST API, so other apps and scripts can consume them. There's also a standalone MCP server if you want to hook it into AI agents like Claude: https://github.com/glanceway/glanceway-mcp
Still actively developed. Most features are free, Pro unlocks unlimited sources.
