Why teams look for ElevenLabs Agents alternatives

EU data residency is Enterprise-only. ElevenLabs' docs describe EU data residency as an Enterprise feature that covers storage; processing may still happen outside the EU unless you use zero retention mode.
Languages depend on the voice model. Agents support the languages of the voice model you choose. The fast models cover Finnish, Swedish, Norwegian, Danish and Dutch, but not Estonian, Latvian or Lithuanian, so check the model, not just the headline count.
You build and maintain it. ElevenLabs Agents is a platform you configure: prompts, tools, telephony and testing are your team's job.

The 6 best ElevenLabs Agents alternatives

1. Sono

Best for: European businesses that want calls handled, with no technical work

Sono is a managed AI phone agent from Helsinki. You get a ready-made agent that Sono's team has trained on your business, connected to your website, calendar and CRM, and tested with real calls before it goes live. It answers inbound calls as an AI receptionist and places outbound calls such as payment reminders from the same system.

Ready-made agents, trained on your business and tested with real calls before go-live
No technical knowledge needed: no flows to design, no code to write
Hands-on support from Sono's own team, typically replying within 24 hours
Strongest in smaller European languages such as Finnish, Swedish, Norwegian, Danish and Dutch
GDPR, EU data hosting, SOC 2 and ISO 27001 for every customer, not only on enterprise plans

Compared with ElevenLabs Agents: ElevenLabs gives you a world-class voice and a platform to build on. Sono gives you a ready-made phone agent, trained and tested for your calls, with EU hosting, SOC 2 and ISO 27001 for every customer rather than only on an Enterprise plan, and support that typically replies within 24 hours.

2. Retell AI

Best for: Teams with some technical capacity that want a visual builder and an API

Retell AI is a San Francisco voice agent platform for automating phone calls. Non-developers build flows on a drag-and-drop canvas and developers work through its APIs and SDKs. It lists SOC 2 Type II, ISO 27001, HIPAA and GDPR, and publishes a 55-language list. Its compliance docs say it does not currently operate services in the EU; GDPR rests on standard contractual clauses.

Compared with ElevenLabs Agents: A builder with a canvas and API and a published 55-language list. It processes data in the US, so it does not solve an EU-residency requirement.

3. Vapi

Best for: Engineering teams assembling their own voice stack

Vapi pitches itself as voice agents for builders: an API-native platform where developers combine the transcription, language-model and voice providers they want. It lists SOC 2, HIPAA and PCI, and documents an EU region for teams that need call data to stay in Europe.

Compared with ElevenLabs Agents: Developer-first and provider-agnostic: you can even keep ElevenLabs voices while choosing the rest of the stack, and use Vapi's EU region.

4. Synthflow

Best for: Agencies and ops teams that want no-code building and EU hosting

Synthflow is a Berlin-based voice AI platform with its own telephony, a visual Flow Designer, templates and an API, plus a white-label programme for agencies with client sub-accounts. It advertises 200+ integrations, and since May 2026 new workspaces can run on an EU cluster that keeps storage and compute inside the EU.

Compared with ElevenLabs Agents: No-code building with an EU cluster that keeps storage and compute in the EU, and a published language list that includes all five Nordic and Dutch languages.

5. PolyAI

Best for: Large contact centres with enterprise budgets and timelines

PolyAI builds customer-service voice agents for large enterprises, with customers such as NatWest and UniCredit. Deployments run on its Agent Studio, from no-code to full code, and it lists SOC 2 Type 2, ISO 27001, PCI and GDPR with regional data residency.

Compared with ElevenLabs Agents: A managed enterprise service with EU data residency, for large contact centres with complex integrations.

6. Bland AI

Best for: US enterprises with engineers and high-stakes call volumes

Bland is a San Francisco enterprise voice AI platform for inbound and outbound phone agents. Developers build on its API and Conversational Pathways flow graph, and Bland's forward-deployed engineers help build the first agent. It says it runs its own speech-to-text, language and text-to-speech models, and lists SOC 2, HIPAA and PCI DSS with self-hosted options.

Compared with ElevenLabs Agents: Runs its own speech and language models end to end, with enterprise engineering help; US-based, with EU residency mentioned but no regions named.

Who should stay with ElevenLabs Agents

Stay with ElevenLabs Agents if voice quality and voice range are the deciding factors, you have a team to configure the agent, and either US processing is acceptable or you are on an Enterprise contract with EU residency.

How to choose a ElevenLabs Agents alternative

Who builds and maintains the agent. You, an agency, or the vendor. This decides your real cost more than any per-minute rate.
Your callers' languages. A language on a list is not the same as a good call in that language. Test with real callers in each language you serve.
Where call data is stored and processed. Ask for the DPA, the data region and the security certificates in writing; storage and processing can sit in different places.
Inbound and outbound in one system. Answering, bookings and outbound calls like reminders or confirmations, without stitching two vendors together.
Integrations. The calendar, CRM, booking or billing systems the agent must read from and write back to.
Who fixes it when it breaks. Support hours, response times, and who listens to the recordings and improves the agent.
