Murf alternative
with a real REST API.
Murf is built for non-developers clicking through a web editor. Audexum is the API for developers who want to programmatically generate voice — at a fraction of Murf's price, with a self-serve API from day one.
"Voices priced for production, not for enterprise sales calls."
- Murf Pro is $29/mo for 24 hours of voice; Audexum Pro is €12 for 1,200,000 credits with no time cap on usage
- Real REST API with Bearer tokens vs Murf's enterprise-only API
- Free 30K credits/month forever; Murf trial is 10 minutes once
- Pay-as-you-go option: €20 per 1M credits — Murf charges by 'voice generation minutes' which compound oddly with regenerations
- Self-serve API access from the free tier — no sales call required
The actual numbers.
What ships in each box.
Murf is a polished UI product for marketers and educators producing one-off voiceovers. The API is locked behind enterprise sales — and the pricing model assumes you'll consume your audio quota in a click-and-edit workflow.
Audexum is the opposite trade-off. Smaller voice library, no lipsync, no fancy editor — but a real API from day one, a free tier you can build on, and prices that don't punish you for shipping at scale.
If your job is to integrate voice into a product (Discord bot, IVR, app accessibility, video pipeline, audiobook generator), Audexum gives you the primitives. Murf gives you a beautiful tool that lives in a browser tab.
Two lines of code.
Same REST shape. Same JSON-in / WAV-out. Just point at our URL with your Audexum Bearer token.

-o hello.wavIs Murf better for non-developers?+
Yes. Murf is a great product if you're producing voiceovers by hand. Audexum's web Studio works for the same purpose, but Murf has more editing affordances. If you need a UI-first tool, Murf may fit. If you need an API, Audexum is simpler and cheaper.
Can I generate audio for video on Audexum?+
You can generate the voice track. You'd need to layer it with your video tool separately. Audexum doesn't do video sync — that's a Murf-specific feature.
Voice variety?+
Murf has more raw voice count. Audexum has 43 carefully curated voices across 33 languages. For most use cases (apps, bots, content) that's enough; if you specifically need 100 American English voices, Murf wins.
