Mastra
Mastra is a TypeScript framework for building and observing long-running AI agents and typed workflows. Developers self-host projects, use built-in observability and memory, and route models through a multi-provider router to run agents in production with audit and telemetry features.
Mastra Platform shows three documented self-hosted tiers: Starter ($0/month), Teams ($250/month) and Enterprise (custom). Each tier lists observability, CPU time, retention, and add-on metering (tokens, storage, compute).Is Mastra right for you?
Good for
- TypeScript engineering teams building self-hosted, observable agent workflows that need to route requests across multiple model providers.
- Core framework is open source under Apache 2.0, letting teams run and modify the framework code directly.
- Model routing connects to many providers through one interface, so teams can switch providers without rewriting agent plumbing.
Keep in mind
- The product emphasizes self-hosting; the pages document 'Self host your Mastra projects' rather than a hosted SaaS plan with a listed price.
- Some enterprise features are source-available rather than fully open-source under Apache 2.0, which may affect access to certain enterprise controls.
- Founders who need a hosted SaaS plan with public per-seat billing and hosted model cost breakdowns; confirm hosted options with Mastra if you prefer a managed service.
Pricing and plan limits
Pricing pages document self-hosted platform tiers, per-unit metering (observability events, CPU hours, token usage, storage) and on-prem Enterprise options; the pages do not present a hosted SaaS plan price for Mastra Cloud.

Choosing a plan
Validate expected metering (observability events, CPU hours, token/storage usage) against your projected workloads and confirm whether you’ll self-host or need a hosted offering.
