DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Faster Whisper, the case for Whispercpp, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Faster Whisper
92.5 / 100- Low-latency execution & AST indexing
- Pricing model: Pro / Usage-based
- Production trade-off: Requires token budget guardrails at scale
When to Pick Whispercpp
91.0 / 100- Open ecosystem & deterministic developer workflow
- Pricing model: Open-Source / BYOK
- Production trade-off: Requires explicit CLAUDE.md / repo rules tuning
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
