Omnivore

Omnivore is a complete, open-source read-it-later solution for people who like reading. It lets you save articles, PDFs, and newsletters to a clean reading environment with support for text highlighting, notes, and labels. It also supports email-based newsletter ingestion, so you can forward newsletters directly into Omnivore.

Key features include full-text search across your entire library, offline reading on mobile (iOS and Android), RSS feed support, and deep integrations with knowledge management tools like Logseq and Obsidian via plugins. The reading experience is clean and distraction-free, with customizable fonts and themes.

Omnivore can be self-hosted using Docker and supports PostgreSQL as its database. It is a strong open-source alternative to Pocket and Instapaper, especially for users who want to connect their reading workflow with note-taking tools. Note: the official hosted service at omnivore.app shut down in late 2024, but the self-hosted version remains fully functional.
