Botpress vs Sierra

Botpress is a platform for building AI agents and chatbots powered by large language models. The Canadian company began with an open-source chatbot framework and later rebuilt the product as a cloud platform centered on a visual studio, where builders combine autonomous LLM nodes with structured workflows and can drop into JavaScript code whenever a step needs custom logic.

Agents draw on knowledge bases built from websites, documents and tables, call external systems through more than 100 integrations, and deploy to web chat, WhatsApp, Messenger, Telegram, Slack, Microsoft Teams and other channels. Human handoff, analytics, versioning and role-based collaboration are layered across plans. Pricing starts with a free plan of 100 conversations, then Plus and Team plans priced by included monthly conversations, with extra conversation packs and an AI usage allowance; usage beyond that allowance is billed, so the total cost depends on traffic and the models you choose.

Botpress fits developers, agencies and product teams building several agents that must follow defined processes and connect to real systems. Non-technical users who simply want a website bot trained on their content will be faster with Chatbase, Voiceflow offers a more design-oriented collaboration experience for conversation teams, and support organizations already on a help desk may prefer Intercom Fin or Zendesk AI agents. The product evolves quickly, so older tutorials and community answers can go out of date.

Sierra is a conversational AI platform that lets large companies deploy branded AI agents for customer service and sales. It was founded in San Francisco in 2023 by Bret Taylor, former co-CEO of Salesforce and chair of OpenAI's board, and Clay Bavor, a longtime Google executive. Its core job is resolving requests end to end, such as changing an order or rebooking a flight, by taking actions in the company's systems rather than just answering FAQs.

Teams build agents in Agent Studio or let Ghostwriter create one from SOPs, transcripts or recordings. A single agent can run across chat, SMS, WhatsApp, email, voice and ChatGPT. Horizon plans multi-step outcomes over days or months, and Insights adds conversation analysis, monitors, experiments and observability. There are no public plans: Sierra sells enterprise contracts with outcome-based pricing, so you pay for resolved conversations or other agreed results.

Sierra fits large consumer brands with high contact volumes and complex back-end systems; customers shown on its site include SiriusXM, Rocket Mortgage, Gap, Wayfair, SoFi and Vanguard. It is not built for small businesses that want a self-serve chatbot. Intercom Fin is easier to switch on inside an existing help desk, Ada targets a similar enterprise buyer with a longer track record, and Yellow.ai is strong in Asian and multilingual markets.

Sierra is growing fast: it reported $100 million in annual recurring revenue in November 2025 and raised $950 million in 2026 at a reported valuation above $15 billion. Expect a sales-led process and a scoped pilot first.
