Mastra vs openrig: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Mastra and openrig — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Mastra
Mastra (team behind Gatsby)
A TypeScript-first agent framework with workflows, memory, streaming, playground, evals, and tracing for building AI apps.
Key features
- Unified Model Interface: Provides a single API to access hundreds of models from dozens of providers (documented access to 1113 models from 53 providers) so developers can switch or compare models without changing application logic.
- Workflows and Orchestration: First-class workflow primitives to compose multi-step agent behaviors and pipelines, enabling complex task decomposition, tool invocation, and sequential processing.
- Long-term Memory: Built-in memory abstractions to persist and recall conversational or agent state across sessions, improving continuity and personalized behavior.
- Streaming Outputs: Support for streaming model responses to enable low-latency progressive output and responsive UX in interactive applications.
- Interactive Playground: A development playground for iterating on prompts, agent strategies, and tool integrations with live testing and debugging.
- Evals and Tracing: Integrated evaluation tooling and tracing to measure agent performance, run automated evaluations, and inspect decision traces for observability and improvement.
- Templates and Example Agents: Ready-made templates (e.g., an AI web search assistant) and sample projects to accelerate building real-world applications.
- Multi-provider Tooling: Facilities to equip agents with external tools, connectors, and integrations while managing provider-specific details through Mastra abstractions.
- TypeScript-first agent framework optimized for modern TypeScript stacks
- Workflow orchestration for multi-step agent behaviors
- Persistent memory management for agents
- Streaming response support for real-time output
- Interactive playground for developing and testing agents
- Evaluation tooling (evals) for measuring agent performance
- Tracing and observability for agent executions
- Unified model interface providing access to 1,113 models from 53 providers via a single API
- Templates and example applications (including a web search assistant)
- Open-source repository and community resources (mastra-ai/mastra on GitHub)
- Course and learning materials for building and deploying agents
Best for
- Building autonomous TypeScript agents that coordinate tools, perform multi-step reasoning, and maintain state with memory across interactions.
- Creating an AI-powered web search assistant that crawls, extracts, and sources open-web information using Mastra templates and connectors.
- Comparing and switching LLM providers easily during development by leveraging Mastra's unified model interface to test dozens of models without rewriting code.
- Developing production workflows that stream partial model outputs to users for real-time feedback while tracing and evaluating agent decisions.
- Prototyping and evaluating agent strategies using the interactive playground and built-in evals to iterate on prompts and measure performance.
- Teaching and onboarding teams through the Mastra course to learn how to equip agents with tools, memory, and MCP patterns in a TypeScript environment.
- Packaging TypeScript-based AI applications with reproducible workflows, templates, and observability for deployment and maintenance.
- Building tool-enabled conversational agents with memory and multi-step workflows
- Creating web search and information retrieval assistants with sourced answers
- Rapidly prototyping and testing agent behavior in an interactive playground
- Integrating many LLM providers through a single unified API for model experimentation
- Deploying production agents with tracing, evals, and observability

OpenRig is open-source software to define a team of Claude Code and Codex agents in YAML and run them as one persistent, managed system.
Key features
- YAML Rig Definitions: Describe an agent team with roles in YAML and boot it with a single command.
- Mixed Harnesses: Run Claude Code and Codex agents together in the same rig, managed as one system.
- Lead Agent Coordination: Talk to a lead agent that coordinates specialists across teams and reports back decisions needing attention.
- Persistent Teams: Keep team work and context at stable addresses instead of a pile of terminal sessions.
- Terminal UI: View the rig as a graph or a table of seats showing runtime, model, context and state, with per-seat detail.
- Guided First Use: A getting-started path installs, launches a two-agent team in your repository and produces one reviewed change.
- Permission Allowances: Optionally lets your agent add scoped native rules so OpenRig commands run without repeated prompts, with an undo.
- CLI Install: Distributed as @openrig/cli on npm, requiring Node.js 22 or 24 and tmux on macOS or Linux.
Best for
- Multi-Agent Coding Teams: Stand up a persistent team of coding agents with defined roles for a repository.
- Cross-Harness Workflows: Combine Claude Code and Codex strengths within one coordinated team.
- Outcome-Driven Delegation: Describe a desired outcome to a lead agent and let it split work among specialists.
- Agent Monitoring: Watch seats, models, context and state of many agents from one terminal UI.
- Reviewed Changes: Have agents produce a change in a repo and another review it before you merge.
- Agent Research Experiments: Prototype and study networks of cooperating agents on your own machine.
