Guild.ai
Agent platform
Vendor-neutral control plane to deploy, run, monitor and govern AI agents built in any framework, with an MCP Gateway for tool and model access, AI Observability, AI Governance, token monitoring and an Optimizer.
Developer tool
Agents that plan, build, test and review bounded engineering tasks from issues and hand engineers validated pull requests, running on the Guild control plane; humans approve and merge.
Mastra
Agent platform
A UI mounted inside a team's own Mastra server for creating and operating internal agents, with multi-tenant workflows, role-based access and channel integrations, licensed for production under Mastra's enterprise licence.
Developer tool
An open-source TypeScript framework that developers use to build, run and observe AI agents and workflows, with a hosted Studio and cloud deployment option.
A shared workspace where a team inspects agent runs through traces and cost, latency and quality metrics, scores outputs with LLM-as-judge or code, runs dataset experiments and versions prompts and agent configurations, open to non-engineering reviewers without source access.
No counterpart
Mastra sells these in a stack layer with no product recorded for Guild.ai yet — nothing on the other side to compare them against.
API service
An OpenAI- and Anthropic-compatible model gateway that routes one API key to 300+ models with provider failover, and adds observational memory that compresses each conversation into notes so agents keep context without rebuilding it.
AI agent
An open-source terminal coding agent with Build, Plan and Fast modes and explore, plan and execute subagents, whose observational memory compresses the session into notes instead of compacting it, so long sessions keep their context.
An open-source software delivery environment where coding agents take a connected repository's issues through investigation, planning, implementation and review to a reviewed pull request, with people deciding at each step; self-hosted or deployed on Mastra's platform.
Infrastructure service
Hosted telemetry store for Mastra agents in production: it keeps the metrics, structured logs and step-by-step traces of model calls, tool calls and workflow steps for every run, with dashboards for cost, latency and quality scores.
Hosted deployment target that runs a Mastra application's agents, tools and workflows as an API server from one command, with routing and scaling handled by Mastra and billing by CPU time and data egress.
