Chatvia vs Rasa: no code, no cap#

Rasa's free edition stops at 1,000 chats a month, and everything else in it is written in Python. Chatvia has no cap and needs no code. That is the comparison in two sentences, but the details matter, and so does where Rasa wins.

My short answer#

Pick Chatvia if you want an AI agent that answers from your knowledge, set up without code, with no chat cap and no license to buy for production.

Pick Rasa if you have Python developers building strict, scripted flows at large scale, and a paid license fits your budget.

What Rasa is#

Rasa is a framework for building conversational AI. Developers write the assistant in Python and set up its flows, actions and channels in code. Its strength is control: strict flows keep the assistant on the path you designed.

You can read the code and host it yourself. The free Developer Edition is capped at 1,000 chats a month. Above that, you need a paid license, and its price comes through sales.

What Chatvia is#

Chatvia is a free, self-hosted platform for AI chat agents. You install it on your own server with one command. Your agents answer from your files, websites and Q&A, and they work on your website, in Slack, Teams, WhatsApp and more.

You get the full source code. There are no plans and no seats.

Where I would call it even#

Both run on your own server. Both let you use any model, including models you run yourself. And both can keep an agent on track: Rasa with strict flows, Chatvia with guardrails. On those points, Rasa is as good as Chatvia.

The cap#

With Rasa, 1,000 chats a month is enough to try it, but not for most live sites. Past that number you need a paid license, priced through sales, on top of what you pay your AI provider.

With Chatvia there is no cap and no license to buy for production. You pay your AI provider for what the model uses, at their price, with nothing added on top. A typical answer from a fast model costs a fraction of a cent. Run an open-weight model on your own hardware and the AI cost can be zero.

Chatvia has no limits on agents, teams or replies, with or without a key. A Pro license key adds more workspaces, the API, capabilities and forms and hides the "Powered by Chatvia" line, for $199 a year.

Who changes the agent#

With Rasa, Python developers do. Flows, actions and channels all live in code, and every change goes through them.

With Chatvia, anyone on the team can. You write the agent's persona and instructions, choose a model, add your knowledge, and test it in the playground. A weak answer gets fixed the same way: open the chat log, write the right answer, and it becomes a Q&A pair. No ticket to a developer.

What is already there#

With Rasa, you build most of the parts around the assistant yourself. In Chatvia they are ready:

• A knowledge base. Files, websites and Q&A, with hybrid search, reranking and source citations.
• A chat widget. One script tag on any website, plus a hosted chat page.
• Analytics. Messages, visitors and trends, with every chat sorted by topic, mood and tone.
• Evaluations. Test questions scored by an AI judge, exact matches, patterns or tool calls.
• Handoff. Your team takes over a widget chat live. In Rasa, handoff goes through other tools.

Tools and actions#

In Rasa, actions are custom code written in Python.

Chatvia agents can use 24 ready-made connectors, like GitHub, HubSpot, Salesforce, Notion and Zendesk, or any MCP server. They can also call your own HTTP endpoints as custom functions. For each tool you choose: it runs, it waits for a person's OK, or it never runs. Every call is logged with its input and result.

Channels#

Rasa connects to the web, Slack, Telegram, Messenger and more, set up in code.

Chatvia has a chat widget, a hosted chat page, voice chats, Slack, Microsoft Teams, WhatsApp, Messenger, Instagram, Telegram and a REST API, all built in, with no code to write.

When I would pick Rasa#

Rasa is the better choice if:

• you have Python developers who want full control in code,
• your assistant must follow strict, scripted flows, like a bank or an airline, and
• you run at large scale and a paid license fits your budget.

Verdict#

Rasa gives developers fine control and asks for code and a license in return. Chatvia gives your whole team a finished AI agent: a knowledge base, a widget, tools, guardrails, analytics and handoff, with no code and no chat cap. You keep your data, you pick the model, and your costs stay flat as your chats grow.

You can install Chatvia and have a first agent answering in a few minutes. No Python needed.
