GitHub - richardr1126/openreader: An open-source read-along document reader server with high-quality TTS options, synchronized highlighting, and audiobook export for EPUB, PDF, DOCX, TXT, and MD.

Sharing my latest release of OpenReader v3.0.0, an open-source text-to-speech document reader and audiobook exporter. It has been live for over a year now, and slowly has gained 300+ GitHub stars.

What is OpenReader?
A Next.js web app for reading and listening to EPUB, PDF, TXT, Markdown, and DOCX files.

• Supports multiple TTS providers: OpenAI, Replicate, Deepinfra, and self-hosted OpenAI-compatible APIs (like Kokoro-FastAPI, KittenTTS-FastAPI).
• Self-hosted: your documents, TTS audio, and settings all live on your own server in SQLite or Postgres and Embedded SeaweedFS or External S3.
• Audiobook export: generate and download m4b/mp3 audiobooks with chapter metadata via ffmpeg.

What's new in v3.0.0?

• TTS now preloads audio across multiple pages ahead of where you are.
  • Audio is cached persistently on the server's embedded or external object storage.
• New Admin panel (set ADMIN_EMAILS in your env) for managing multiple named TTS providers with separate API keys.
  • Site-wide feature flags (user signups, provider restrictions, etc.) are now manageable from the Admin panel at runtime without redeploying.
