Retell AI White-Label Review & European Alternative for Agencies (2026)

Retell AI is a US developer platform for building, testing and deploying AI voice agents that answer and make phone calls. Its homepage tells teams they can build, update, test and deploy agents without relying on Retell for every change, so that your team stays in control. It offers outbound and batch-call APIs, web calls, and its own or your own telephony.

It fits an agency or product team with developers who want full control over prompts, models and call flows. This page looks at it from the white-label angle. For the platform view, see AInora vs Retell AI and Synthflow vs Vapi vs Retell.

Not on its own. The Retell pricing page and the Retell partner program (both checked 11 October 2026) do not mention a white-label plan, rebranding, reseller pricing, client sub-accounts or a custom domain. The partner program is aimed at agencies, developers and technology providers, and offers leads, a partner listing, co-marketing, priority support and early access to new features.

What agencies get instead is workspaces. The Retell docs advise agencies to create one workspace per client, each with its own payment method, credit balance, invoices and usage. Workspaces are created by hand in the dashboard; Retell does not expose an API for that. A branded client portal and rebilling come from a third-party layer: Retell lists white-label apps such as Call Supplai in its App Partner Directory, and VoiceAIWrapper resells Retell under your brand on your own Retell account.

On the pricing page (checked 11 October 2026), AI voice agents cost $0.07 to $0.31 a minute, depending on the model, voice and telephony you pick. There are no platform fees and no feature gating, and you start with $10 in free credits. Retell phone numbers are $2 a month, every account includes 20 concurrent calls, and extra capacity is $8 per concurrent call a month. Enterprise is priced on request.

For an agency, that is the usage cost only. The white-label app on top, the time your team spends building and maintaining each client's agents, and any minute markup you add are separate. The full Retell cost breakdown is in Retell AI pricing 2026. AInora is priced individually, after a call.

Retell's compliance page states: "we do not currently operate services within the European Union". For EU and UK personal data it offers a self-signable DPA that includes the EU standard contractual clauses, at no extra fee, and it lists HIPAA, GDPR and SOC 2 Type 1 and Type 2. We found no EU hosting option on its pricing or compliance pages (checked 11 October 2026).

AInora stores data on servers in Germany and Finland. In the standard setup, calls are processed in the EU and the US under the EU-US Data Privacy Framework and standard contractual clauses; a full-EU setup is available on request, and regulated clients get a DPA. Every agent discloses that it is an AI in line with Article 50 of the EU AI Act, and outbound rules are mapped country by country. The details are on the security page.

Retell is the better choice if your agency has developers and wants to own every detail of each agent: the prompt, the model, the voice and the call flow. It suits teams that want to start today on a published per-minute price with free credits and no sales call, and agencies with US clients in healthcare, where a HIPAA BAA is part of the offer.

AInora is not built for that. It has no self-serve sign-up and no free trial, its price is set individually after a call, a short scoping call comes first, and a deployment takes about two weeks from kickoff to live. If you want to assemble every agent yourself, a developer platform is the better category.

Choose Retell AI if you have people who will build and look after the agents, you are happy to add a white-label app for branding and rebilling, and your clients accept a US provider covered by standard contractual clauses.

Consider AInora if you are looking for a European alternative to Retell AI and would rather sell voice agents than build them: AInora builds and operates each deployment, white label is included, you keep the brand and the client relationship, and your clients' data is stored on servers in Germany and Finland (full-EU setup on request) with AI Act disclosure, 90+ languages and outbound as well as inbound. Start with the partner program or the 14 questions to ask any white-label provider.
