Build on EasyVoice — an OpenAI-compatible TTS API, $9.99/mo flat, unlimited characters
EasyVoice Pro is $9.99 a month, flat, with no per-character meter. At real volume that is roughly $1 per 1M characters at the fair-use line, against OpenAI tts-1 at $15 per 1M characters (checked September 2026). EasyVoice costs less than tts-1 once you cross about 666,000 characters a month; below that, tts-1 can cost less. The API follows OpenAI's TTS request shape: change the base URL and the key, and keep the rest of your code.

The per-1M math, same market, one table
| Provider | Price | The catch |
|---|---|---|
| EasyVoice Proflat rate | $9.99/mo flat — unlimited | No credits, no meter; web app + long-form studio + OpenAI-compatible API |
| OpenAI tts-1 | $15 / 1M | No free tier — bills from the first character |
| ElevenLabs API | billed in credits, not characters | Best-in-class voice cloning quality; billed in credits, not characters |

Swap the base URL
The API follows the OpenAI TTS request shape, so OpenAI's own SDK works against it. Migrating an existing integration means changing the base URL and the API key; OpenAI's six original voice names (alloy, echo, fable, onyx, nova, shimmer) are accepted and map to EasyVoice voices such as af_alloy — the request body, the SDK call and the response handling stay the same. On a free key only nova works; the other five need Pro or the 7-Day Pass.

The workflow moat
Budget resellers can sell hosted Kokoro-82M for cents. What they can't sell: the pipeline built around it.
Submit long inputs as a background job instead of waiting on a single request.
Multi-speaker episodes with bed music and stitching, from a single API call.
Clone a voice from a short sample and reuse it across every surface.
Connect Claude, ChatGPT, or Cursor directly — same key, no HTTP glue code.
The OpenAI Python SDK (2.54.0 and 3.13.0) returns clean, typed errors against our base_url (tested 2026-09-15). Exact versions and results on /api-docs.
Who each option is actually best for
| Provider | Best for | Honest tradeoff |
|---|---|---|
| EasyVoiceflat rate | Flat-price, full workflow | $9.99/mo unlimited characters with a web app, long-form studio, podcasts, cloning, and an OpenAI-compatible API — not the highest-fidelity voice model on the market. |
| ElevenLabs | Voice-cloning quality | Still leads the market on voice-cloning realism and fine-grained emotion control — billed in credits, no flat unlimited tier. |
Free forever tier — 5,000 characters/day, no card.
