About Rasa
Rasa is an AI agent platform for product teams that build customer-facing assistants. It offers tools to build agents through a visual studio, code, or a coding agent. Agents can be tested automatically on simulated text and voice conversations, and their versions can be compared before release. Rasa also reviews live conversations, tags and groups what it finds, and reports issues to the team. Agents can run across channels such as a phone hotline, Slack, web chat, WhatsApp, and email. The homepage states that secure deployment, audit trails, and voice come standard for enterprise teams, and that deployment can be on the customer's own infrastructure. Rasa's homepage cites a Forrester Wave 2026 report naming it a Strong Performer, and it lists customer results. These figures are vendor-reported and were not independently verified here. Pricing is not listed in the source.
