Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited TTS engine support

   Say.js relies on external plugins for TTS engines, and the ecosystem of available plugins is small and not actively maintained.

2. 02

   Poor documentation

   The official documentation lacks comprehensive examples and detailed explanations for advanced use cases, making it difficult to fully leverage the library's capabilities.

3. 03

   Performance issues at scale

   Say.js can become slow when generating a large number of audio files simultaneously due to its synchronous nature and lack of built-in concurrency support.

4. 04

   Vendor lock-in with specific TTS engines

   Switching between different TTS engines requires significant code changes, as each plugin has a unique API and configuration options.

What it does well

• Easy to integrate into Node.js applications

• Supports various TTS engines through plugins

• Lightweight and efficient for server-side use
