Synthflow alternative
Synthflow pricing, explained, and a Synthflow alternative.
Synthflow is an enterprise conversational AI platform for AI voice agents. As of Nov 2026 it is sold only as an annual enterprise agreement, scoped to your call volume, telephony and integrations, with no free plan, no trial and no published per-minute rate. White-label is part of that agreement.
That suits mid-market and enterprise teams that want a contract and engineers to launch with. If you would rather build and test an agent yourself, pay your model providers directly, or resell voice agents under your own brand through a partner programme, VocalLabs is the Synthflow alternative to compare.

White-label: a contract clause, or a partner programme.
Synthflow folds white-label into its annual enterprise agreement and does not publish what it adds to the price. The VocalLabs white-label programme is built for agencies and resellers: VocalLabs builds and runs the voice AI, partners brand it, price it and sell it, and their customers run on it.

run on it every day
- Your brand on every screen
- Your logo and colours on the console, your domain on the console and the calls, your name on the reports. VocalLabs is never named.
- Partner rates, your price
- Buy at partner rates and sell at yours, per minute or per seat. The margin is yours.
- One console for every client
- Multi-tenant isolation, with plans and limits set per client and usage for every account in one place.
- One rule
- VocalLabs never contacts your customer. We support you; you support your clients.
Who should choose Synthflow, and who should look elsewhere.
An enterprise contract is the right shape for some buyers. These are the cases on each side.
- 01Synthflow
You want engineers on the contract
Synthflow’s forward-deployed engineers implement, test and launch agents with your team, where the agreement includes them.
- 02Synthflow
You need PCI DSS
Synthflow lists PCI DSS v4.0.1 in its trust centre, alongside SOC 2 Type 2 and ISO/IEC 27001. If card data runs through your calls, weigh that.
- 03VocalLabs
You want to build before you buy
Build an agent in the VocalLabs dashboard or with Copilot, and test it in browser sessions before anything is published.
- 04VocalLabs
You want your own model bills
Connect your own OpenAI, Gemini, Deepgram, ElevenLabs, Sarvam and other accounts. They bill you directly, at your rates.
- 05VocalLabs
You are an agency or reseller
Partner rates, a branded console on your domain, and per-client plans and limits. Partners go from signup to first client in days.
- 06VocalLabs
You need more than voice
The same agent on a phone number, in the browser, on WhatsApp and Telegram, and as a video avatar.
Evaluating VocalLabs as a Synthflow alternative.
- 01
Describe the agent
Write the job in the dashboard, or let Copilot draft the prompt, models and tools from your description. Add the answers it must give word for word as FAQs.
- 02
Connect your keys and tools
Add your own model and speech provider accounts, then connect tools: HTTP requests, MCP servers such as Calendly or HubSpot, handoffs to a person, and webhooks.
- 03
Test it
Run voice, video and text sessions in the browser and read the transcript, tool calls and provider usage for each.
- 04
Connect a number
Link your Twilio, Plivo, Exotel or Vobiz account, import a DID and point it at the published agent.
- 05
Reselling? Brand it
Partners agree rates with us, put their logo and domain on the console, and onboard clients with their own plans and limits.
