A typed exception hierarchy, with RetryAgentRun and StopAgentRun to steer the loop from a tool (16). Runs continue by run ID after a pause and AgentOS has a durable queue, which is off by default (16). Few required parameters, Python only (8).\n- Mastra (92): An MCP client in about ten lines with listTools() for static or listToolsets() for per-request tools, and ToolSearchProcessor for loading tools on demand (25). Step limits, memory windows and processors such as a token limiter control what reaches the model (20). MastraError with ids and categories, and processors can abort with a reason the caller can read (17). Workflow step retries, snapshots and durable agents for resuming (20). create-mastra scaffolds a project and the model router takes a plain string, but it's TypeScript only (10).\n\n### Transparency \u0026 trust: Agno +12\n\n- Agno (84): Apache 2.0 (30). The telemetry page lists the fields sent and says identifiers are not hashed, and the pricing page says the control plane holds no copy of customer data. The terms and privacy pages render only with JavaScript and were not read, and no retention period for telemetry was found (15). Migration guides for 2.0 and 3.0 and migration notices on what was removed, with no written deprecation policy found (10). Telemetry is disclosed in the README and docs with an opt-out, though the environment variable does not cover AgentOS or evals (18).\n- Mastra (72): Apache 2.0 for the core, with ee/ directories source-available under the Mastra Enterprise License (25). The privacy policy (last published 25 April 2025) covers the website, the Teams plan states six months' retention, and the subprocessor list sits in a trust centre our reader couldn't render (15). Migration guides and deprecation warnings, without dated removal windows (12). Every telemetry stream is documented with links to its source and one opt-out, and the reference now spells out what the project identifiers can be correlated with (20).\n\n### Payments \u0026 pricing: Mastra +10\n\n- Agno (50): No payment protocol (0). Self-hosted rule, with the paid option scored. The control plane has public plan prices, Free at $0 and Pro at $150 a month, with Enterprise by quote (10). The package installs with no card (20) and runs with no Agno account (20).\n- Mastra (60): No payment protocol (0). Scored on the hosted platform, whose per-unit prices are public without a login ($10 per 100K observability events and $0.35 a CPU hour on Starter) (20). The Apache 2.0 packages install with no card (20) and no account, and run any model (20).\n\n### Maintenance \u0026 community: Mastra +10\n\n- Agno (86): 3.1.12, tagged 29 October 2026 (30). 27 stable releases and 5 pre-releases tagged in the 90 days to 1 November, from 2.8.7 on 5 August to 3.1.12 (20). Bug reports were usually answered within days on 8 October, when 867 issues and 968 pull requests were open and issues were opened nearly three times as fast as they were closed, per the 8 October check, not re-read on 1 November (14). The Python package is current (15). CI runs lint, types and tests with pinned development tools. No Dependabot configuration file is in the repository (7).\n- Mastra (96): @mastra/core 1.82.0 on 2026-11-04 (30). 27 stable releases in the 90 days to 6 November, 8 of them since 6 October (20). 436 open issues on 6 November, all 50 newest issues commented and 24 of them closed (22). Client, MCP and store packages are current, and @mastra/mcp 1.x stays supported beside 2.x (15). Renovate and CI configured, with the newest runs on main passing (9). 30+20+22+15+9 = 96.\n\n### Schema \u0026 documentation: Mastra +8\n\n- Agno (90): A class reference under docs.agno.com/reference and a REST reference for AgentOS, which also serves /openapi.json (25). llms.txt with 3,985 lines, llms-full.txt, a Markdown twin of each page and a docs MCP server (10). Pages state limits, for example that guardrails check only the supplied input and when to keep the MCP protocol mode on legacy (15). Pydantic-typed classes and tool signatures, with a py.typed marker (13). Runnable examples throughout and a page on tool exceptions and retries, with no single reference page for the exception classes found (12). Dated changelog and release notes per version (15). Framework reading.\n- Mastra (98): Typed TypeScript API with a reference section (25). llms.txt with a when-to-use list and condensed instructions for coding agents (10). The docs say when to use durable agents, and point multi-agent users from `.network()` to supervisor agents (20). Tools take Zod schemas (15). Examples on every page, and MastraError with ids and categories documented, though errors are spread across pages (13). Per-package changelogs and migration guides (15).\n\n## Score by category\n\n| Category | Weight | Agno | Mastra | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 83 | 87 | Mastra +4 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 90 | 98 | Mastra +8 |\n| Agent ergonomics | 13% (16.2 this run) | 76 | 92 | Mastra +16 |\n| Security \u0026 auth | 14% (17.5 this run) | 64 | 67 | Mastra +3 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 50 | 60 | Mastra +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 86 | 96 | Mastra +10 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 84 | 72 | Agno +12 |\n| Negative events | ≤15 | -5 | -8 | |\n| **Total** | | **70.9 · BB** | **74.2 · BB** | |\n\n## Facts side by side\n\n| Fact | Agno | Mastra |\n| --- | --- | --- |\n| Kind | Agent framework | Agent framework |\n| Vendor | Agno Inc. | Kepler Software, Inc. |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | API key | API key |\n| Pricing | Free | Free |\n| x402 | no | no |\n| Licence | Apache-2.0 | Apache-2.0 for the core.

Usage telemetry is on by default with unhashed identifiers, and 3.1.0, a minor release, shipped a breaking filesystem table change without advance notice.\n\n**Mastra.** A TypeScript framework with agents, workflows with suspend and resume, memory, an MCP client and server, per-server tool approval and built-in guardrail processors including a prompt-injection detector. On 17 June 2026 malicious versions of its npm packages were published, and the CLI, server and Studio send usage analytics by default, with token counts every 15 minutes.\n\n## Before you call either\n\n### Agno\n\n1. Set AGNO_TELEMETRY=false before the first run, and pass telemetry=False to AgentOS and to each eval, which ignore the variable\n2. Configure JWT_VERIFICATION_KEY with AgentOS authorisation switched on, or OS_SECURITY_KEY, before exposing AgentOS. With neither set, REST and MCP routes take no credential\n3. Mark tools that write with requires_confirmation, and resume with continue_run once every requirement is resolved\n4. Set tool_call_limit on agents. The default is None\n5. Install extras for what you use, such as agno[mcp] for MCPTools and agno[os,mcp] for AgentOS with its MCP server\n\n### Mastra\n\n1. Set MASTRA_TELEMETRY_DISABLED=1 in every environment that runs the CLI, the server or Studio\n2. Pin exact versions with a lockfile, and make sure no 17 June 2026 release such as @mastra/core 1.42.1 is installed\n3. Set requireToolApproval on MCP servers that write, and allowedHosts when server URLs come from configuration\n4. Add PromptInjectionDetector as an input processor when tools return web or user content\n5. Use supervisor agents through generate() or stream(). `.network()` is deprecated\n\n## Questions\n\n### Which is better for AI agents, Agno or Mastra?\n\nMastra scores 74.2 (BB) on agent readiness against Agno's 70.9 (BB), and leads in 6 of 7 scored categories. Agno leads on transparency \u0026 trust.\n\n### Are Agno and Mastra open source?\n\nYes. Agno is open source (Apache-2.0). Mastra is open source (Apache-2.0 for the core. Code under ee/ directories is source-available under the Mastra Enterprise License, free for development and testing).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agno-vs-mastra.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agno-vs-mastra.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agno\", \"b\": \"mastra\"}`.
