Retell AI is a hosted platform for AI phone agents. VEXYL is built for teams that need the agent next to their own telephony and data: self-host it, or use VEXYL Cloud, with Indian-language voice built in.
| VEXYL | Retell AI | |
|---|---|---|
| Where it runs | Your servers, your VPC, or VEXYL Cloud | Vendor-hosted cloud |
| Telephony | Your own SIP trunk, Asterisk / FreePBX, PSTN, WebRTC | Vendor telephony or SIP into their cloud |
| Agent builder | LiteBot: prompts, tools, knowledge base, visual flows, auto-dialer | Hosted agent builder |
| Model choice | Bring your own keys for LLM, STT and TTS, switchable per bot | Platform-selected options |
| Data residency | Audio, transcripts and keys on your infrastructure when self-hosted | Vendor cloud |
| Indian languages | Sarvam, Smallest and open-source VEXYL-STT built in | Depends on available voices and models |
| Pricing model | Free self-hosted Developer edition; licence by concurrent calls | Usage-based per minute |

New to VEXYL? Start with the AI voice agent platform overview or the LiteBot agent builder.
Same platform, two ways to run it. Start self-hosted for free, or let us run it for you on VEXYL Cloud.
Run the gateway and LiteBot on your own servers or VPC. Your audio, transcripts and keys never leave your infrastructure.
We run the gateway for you. Point a SIP trunk from your PBX at us, drop the browser widget on your site, and receive signed webhooks.
The main difference is where it runs and who owns the stack. VEXYL can run entirely on your servers with your own SIP trunk and model keys, or on VEXYL Cloud.
Yes. Use the outbound API for single calls with per-call context, or the LiteBot auto-dialer for CSV campaigns with retries and webhooks.
Through Sarvam, Smallest and the open-source VEXYL-STT server, VEXYL covers major Indian languages; VEXYL-STT alone supports 14.
