Mastra Platform free hosting

Mastra Platform

Hosting a low-traffic TypeScript agent or workflow that exposes its own callable HTTP API.

Facts

Free allowance
24 CPU-hours/month
Plan limits
10 GB egress · 100K observability events · unlimited deployments
Storage
1 GB platform data storage; 250 MB retrieval storage; separate 1 GB database storage and metered database usage are listed on Starter.
Account
Starter account required. Provider says allowances can be tested before providing a card; exact signup/card verification not independently tested. Model usage costs are separate.
Retention
15 days for observability data and stale threads; long-term deletion for idle projects or non-observability assets was not verified. Multi-environment staging/preview deployment requires Teams/Enterprise.
Custom domain
Managed live API endpoint URL provided by platform. A Free custom-domain connection is not established.
Password protection
No shared visitor-password feature verified. API authentication is via JWT or supported identity provider, which is different from a viewer password.
Billing
Monthly free allowances, then metered usage from prepaid credits; optional auto-top-up. Zero-balance enforcement and default spend guard not verified.
Execution
Request-driven TypeScript agent/workflow API; mastra deploy publishes a public endpoint. Filesystem is ephemeral. Always-on mode is paid.

Worth knowing

24/7 persistent server uptime is $100/project even on Starter, so the included CPU time is not an always-on server. Usage past free allowances is metered; external AI model calls can cost money. Multiple deployment environments are paid-only.

How we match

Choose the kind of thing you made and the features you need. The results respond to the capabilities recorded in our directory.

Each result explains its fit or mismatch. Unverified commercial-use permission is marked for a terms check. Unknown free features don’t count as confirmed fits.

Apps can run in the browser, as serverless functions, or on a persistent server. The second step changes with your choice: web pages or file links for sites and files, runtime options for apps. For agents and tools, choose an agent service, MCP server, or code sandbox. A sandbox or serverless endpoint is not a continuously running process. In each group, select several to see hosts that support any selected option. Leave them blank to explore broadly; your agent can check the runtime before publishing. Docs & media candidates also need an exact file-format and size check. Commercial mode removes records with documented personal or non-production restrictions; it does not certify permission on other hosts.

Open a host to read its limits and sources. The agent brief packages your choices and those limits into instructions you can paste into your agent. It does not publish anything.

Each record has its own review date (October 11–15, 2026); deployments, privacy, support, and uptime have not been tested. There are no paid placements or affiliate links in this edition.
