- Agno, good for Python teams that want agents, teams and workflows plus a self-hosted server with REST, MCP, approvals and scheduling in one package. Ahead on Transparency & trust, 84 against 72.
- Mastra, good for TypeScript teams that want agents, workflows, memory, evals and a local Studio in one framework. Ahead on Schema & documentation, 98 against 90; Agent ergonomics, 92 against 76; Payments & pricing, 60 against 50; Maintenance & community, 96 against 86.

Why the edge:
- Agent ergonomics, Mastra +16: Agno 76 (An agent with an MCP server is about ten lines through MCPTools, with include_tools, exclude_tools and tool_name_prefix (22). tool_call_limit exists but defaults to None, and sessions, history and compression are configurable (14). 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).); 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).)
- Transparency & trust, Agno +12: 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).); 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).)
- Payments & pricing, Mastra +10: 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).); 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).)
- Maintenance & community, Mastra +10: 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).); 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.)
- Schema & documentation, Mastra +8: 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.); 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).)
