## Which one, for what

### Pipecat (B)

Good for: Python teams that want to own a voice agent's pipeline, pick each speech and model provider, and host it themselves or on Pipecat Cloud.

Ahead on:
- Reliability, 72 against 40
- Security & auth, 57 against 46
- Payments & pricing, 60 against 40
- Maintenance & community, 87 against 61
- Transparency & trust, 81 against 47

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

Watch for: No tool-approval or confirmation step, and no prompt-injection guidance, for tools that act on a caller's speech

### Vocily AI (D)

Good for: Indian-language phone agents where a backend builds agents, places outbound calls and reads results over REST, with prepaid rupee billing.

Ahead on:
- Agent ergonomics, 84 against 72

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page, incident history or SLA was found

## Verdicts

**Pipecat.** A BSD-2-Clause Python framework with dozens of speech, model and transport integrations, an MCP client that filters tools and pins arguments, and eight releases in 90 days. It has no tool-approval step, and 1.12.0 can send OPENAI_API_KEY to other OpenAI-compatible providers when no key is passed, a flaw fixed on main but not yet released.

**Vocily AI.** The REST API is documented in detail for a product a few months old, with an OpenAPI 3.1 file, required idempotency keys on calls, a Retry-After header on 429 and signed webhooks. No status page, SLA, SDK or security programme was found, and two releases in September 2026 removed fields under `/v1` on the day they were announced.

## Before you call either

### Pipecat

1. Pass `api_key` explicitly to every OpenAI-compatible service such as Groq, Cerebras or OpenRouter. On 1.12.0 a missing key sends `OPENAI_API_KEY` to that provider
2. Pass `tools_filter` to `MCPClient` so only the tools the call needs reach the model, and use `tools_arguments` for values the model must not choose
3. Gate tools that book, pay or send in your own handler. Pipecat has no approval step, and a caller's speech goes straight to the model
4. Keep the development runner on localhost. Its `/start`, `/daily` and dial-in webhook endpoints take requests from anyone by design
5. Pin a minor version and read the breaking-change flags in CHANGELOG.md before upgrading, since minor releases remove and rename APIs

### Vocily AI

1. Send a fresh UUID in `Idempotency-Key` on every `POST /v1/calls`. The API refuses the request without it
2. Pass a `from_number` the workspace holds. The shared Test Number returns 403 from the API
3. Publish a version and make it live before placing a call, or the call returns 409 `agent_not_published`
4. Branch on `detail.code`, falling back to the top-level `code`. A 429 body is flat, so read `Retry-After`
5. Read `currency` on every call and chat record. Costs are in rupees or dollars depending on the organisation
