ElevenLabs → Piper
What it saves, what actually moves, what you rebuild — and the thing that catches people.
What it costs, and what it saves
ElevenLabs bills per character and production usage reaches hundreds monthly. Piper runs on CPU — a Raspberry Pi manages real-time synthesis.
Moves cleanly
Nothing. Different models, different voices, different quality ceiling.
You rebuild
The integration, and your expectations. Be honest about the gap.
What ElevenLabs costs you today
Creator is about $22/month for roughly 100,000 characters and Pro about $99/month for roughly 500,000. API usage is billed per character, roughly $0.06–$0.30 per 1,000 characters depending on plan and model — the Flash model sits near the bottom of that range and the multilingual models near the top. At sustained volume this compounds quickly: a million characters a month on a multilingual model lands in the region of $1,000/month.

What actually holds you in
Voice clones live in ElevenLabs' account and are not portable — a cloned voice cannot be exported and used elsewhere, so the more voices you build the more expensive leaving becomes. Generated audio files are yours, but the pipeline that produced them is not.
What you are moving to
Piper is a fast, local neural text-to-speech system built for constrained hardware — it runs comfortably on a Raspberry Pi and powers the voice in several self-hosted home-automation stacks. It covers 30+ languages with a large library of pre-trained voices. Quality does not match Kokoro or ElevenLabs, but nothing else runs this well with this little silicon.
Free — GPL-3.0. Runs on CPU, including single-board computers; effectively costs electricity.
Piper strengths
- Runs on very low-power hardware, including a Raspberry Pi
- 30+ languages with a large pre-trained voice library
- Fully offline — nothing leaves the device
- Proven in production inside self-hosted voice assistants
What you give up
- GPL-3.0 is copyleft — commercially usable, but check it against how you distribute
- Noticeably behind Kokoro and ElevenLabs on naturalness
- No voice cloning
The migration, step by step
- 1Download Piper and a voice model, then synthesise a real script from your product
- 2Play it to someone who has not been part of the decision and watch their reaction
- 3If quality passes, wrap Piper in a small HTTP service
- 4Swap the client call
- 5Keep ElevenLabs for anything customer-facing where voice quality is the product
The gotcha
The quality gap is real and larger than benchmark comparisons suggest. Piper is excellent for accessibility, notifications and internal tooling; it is not ElevenLabs for narration, and pretending otherwise gets caught by users rather than by tests.
When to stay on ElevenLabs
Voice quality is customer-facing, or you need voice cloning or emotional range.
