Rivet is completely free with 7 features included. No paid tiers offered, making it perfect for budget-conscious users.
Yes, Rivet is completely free and open-source under the MIT license, with no paid tiers, seat-based fees, or usage-based billing from Ironclad itself. You only pay the underlying LLM provider (OpenAI, Anthropic, etc.) for API calls your graphs make. The desktop application can be downloaded directly from the Rivet website or GitHub, and the full source code is available for inspection, forking, and self-hosting. This pricing model is unusual in our directory — most visual AI development tools charge $20–$100+ per seat monthly.
Rivet was built by Ironclad, the leading digital contracting platform used by legal teams for contract review and obligation tracking. It originated as an internal tool when Ironclad's engineers struggled to build AI agents programmatically in code. Rivet is actively used in production at Ironclad itself, and publicly endorsed by CTOs and executives at Attentive, Bento, and AssemblyAI. Todd Berman (CTO) calls it 'the best tool out there' for collaborative prompt chain development, and Bento has used it to ship AI-powered product experiences.
LangChain is a code-first Python/JS framework with no native visual editor, while Flowise is a browser-based visual LangChain wrapper typically self-hosted as a web app. Rivet differs by being a desktop application whose graphs compile to YAML files that live in your Git repository, enabling standard pull-request reviews. Compared to the other visual AI development tools in our directory, Rivet's strengths are its remote debugger, code-review-friendly file format, and zero cost. LangChain has a larger ecosystem; Rivet has tighter collaboration ergonomics for engineering teams.
Rivet supports the major commercial LLM providers including OpenAI (GPT-4, GPT-3.5), Anthropic (Claude models), and integrations with tools like AssemblyAI for audio transcription and understanding. Because graphs are configurable nodes, new provider support can be added via the plugin system — AssemblyAI's integration is a publicly cited example of a third-party extending the Rivet ecosystem. Self-hosted and local models can also be wired in via custom nodes. Check the official documentation for the current full provider list as new integrations ship regularly.
Yes — this is the core deployment model. You design and iterate on prompt graphs in the Rivet desktop IDE, then execute them inside your own application using Rivet's TypeScript/Node.js SDK. The remote executor lets you observe live graph execution from the Rivet desktop app while your production application runs the graph, which is how teams debug real user traffic. Graphs are just YAML files checked into your repo, so deployment is essentially shipping a config file plus the SDK dependency. This architecture avoids vendor lock-in to a hosted runtime.
It's completely free — no credit card required.
