Guzli vs Vapi, side by side
Choose Guzli if ops will run website chat plus the phone from one knowledge base and one bill. Choose Vapi if you have engineers and want API-level control to assemble every component. Choose Bland if you need owned voice infrastructure.
| Feature |  | Vapi |
|---|---|---|
| Decision criteria | ||
| Ops can run it without a pull requestGuzli is a no-code agent. Vapi is API-first. Bland has a builder; production still usually wants an engineer | Yes | No |
| Bring-your-own STT / LLM / TTS keysVapi is the assembler. Guzli swaps providers in the UI and bundles them in the talk rate. Bland owns the stack | Partial | Yes |
| One published invoice (plan + bundled ¢/min)Vapi $0.05/min is hosting; STT, LLM, TTS, and telephony stack on. Bland bundles talk ¢/min, then platform fees | Yes | No |
| Start on a self-serve plan, no sales call | Yes | Partial |
| No per-resolution fee | Yes | Partial |
| Team members included in the plan, not billed per seat | Yes | Partial |
| Agent stays online when usage runs over | Yes | Partial |
| Choose the AI model each agent runs on | Yes | Partial |
| Channels | ||
| Vendor-owned voice infrastructureBland runs its own stack. Vapi orchestrates providers. Guzli is cloud SaaS, not Bland Enterprise | No | No |
| Website chatbotGuzli includes site chat. Vapi messaging is a developer surface. Bland lists web chat on Enterprise, not self-serve support chat | Yes | No |
| Inbound phoneAll three answer inbound. Guzli Standard is 3 concurrent lines; Pro is 8 | Yes | Yes |
| Outbound at contact-center volumeVapi and Bland scale concurrency for campaigns. Guzli outbound fits 3–8 lines, not a 50-line dialer | Partial | Yes |
| Shared knowledge for chat + voiceGuzli trains once. On Vapi and Bland, retrieval is a voice-stack problem; the website is a separate product | Yes | No |
| Unified inbox + auto-create ticketsGuzli is the front line into Zendesk or HubSpot. It is not an ITSM and not a Vapi replacement | Yes | No |
| AI replies to support email | Yes | Partial |

| Named tools (Shopify, Stripe, Calendly, Zendesk)Guzli ships named allowlist tools (Shopify, Stripe, Calendly, Zendesk, HubSpot, Salesforce, Slack, WhatsApp, Zapier, custom API) when those jobs apply. Voice APIs let you wire your own tools | Yes | Partial |

Frequently asked questions
Choose Guzli if ops will run website chat plus the phone from one knowledge base and one bill. Choose Vapi if you have engineers and want API-level control to assemble every component. Choose Bland if you need owned voice infrastructure.
Public card on vapi.ai/pricing (read 20 Sep 2026): usage-only prepaid hosting $0.05/min plus at-cost speech-to-text, language-model, and text-to-speech (or $0 with your own keys). Usage-only includes 4 concurrent lines; Core 10; Pro success package is 10% of hosting with a $999/mo minimum and 30 lines. HIPAA appears as a paid add-on on the comparison table. The headline rate is hosting only.
Migration is moderate; plan for about a day. 1. Connect the website plus Zendesk, HubSpot, or Salesforce tickets so Guzli trains chat and voice together. 2. Forward your existing number for inbound, or connect a Guzli number. 3. Paste the Vapi prompt and map tools to Shopify, Stripe, Calendly, or custom API actions — do not lift the assistant graph node for node. 4. Turn on website chat so the inbox covers Email, Chat, Voice, Slack, and WhatsApp. 5. Keep Vapi for any product you sell that still needs a voice API. Run a short parallel pilot, then switch front-line traffic once answers and handoffs are stable.
Yes. Hobby, Standard and Pro are bought self-serve on the pricing page with no sales call: sign up, connect your website and help center, and test the agent on your own content. Enterprise is the plan that starts with a demo.
One Guzli agent answers website chat, support email, WhatsApp, Messenger, Instagram and Slack, and on Standard and Pro it also answers and places phone calls, all from the same knowledge base and the same inbox.
Guzli is SOC 2 Type II certified and GDPR compliant, and Enterprise plans add SAML single sign-on, custom roles and permissions, and audit logs of every dashboard change. Your data is never used to train models.
