●●SolidSolve My ProblemSlick

Unified TTS interface lets you swap providers without rewriting integration code.

Strengths
  • •Lazy base64 encoding saves memory by only computing formats you access.
  • •Zero runtime dependencies keeps bundle size small for edge and browser.
  • •Smart retries handle 5xx errors automatically without custom logic.
Weaknesses
  • •Still requires managing API keys for each provider separately yourself.
  • •Doesn't solve cost optimization or routing logic between providers.
