Products, side by side

Algorithmic pairing — assembled from recorded fields, not hand-checked

Cognition

AI agent

DevinAI agent

Autonomous coding agent that plans, writes, tests and ships code from a task description.

Devin CLIAI agent

Local command-line coding agent that runs in the developer's terminal against local files, with Devin Cloud integration; bundled with Devin Desktop and presented by Cognition as a separate tool from the cloud-based Devin.

Developer tool

Devin DesktopDeveloper tool

Desktop coding environment running Devin's agents locally, including custom background agents that carry a team's context between sessions.

Devin ReviewDeveloper tool

Devin Review uses AI to review code changes and detect issues in diffs.

Devin Security SwarmDeveloper tool

Devin Security Swarm finds codebase vulnerabilities and creates pull requests to remediate them.

FusionDeveloper tool

Multi-agent coding architecture pairing a frontier 'lead' model (planning/review) with a cost-efficient 'sidekick' (execution), up to 39% more efficient than other coding harnesses on major benchmarks; available now in Devin Desktop and Devin CLI.

Mastra

AI agent

Mastra CodeAI 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.

Mastra FactoryAI agent

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.

Developer tool

MastraDeveloper 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.

Mastra StudioDeveloper tool

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.

API service

Mastra GatewayAPI 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.

Agent platform

Mastra Agent BuilderAgent 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.

Infrastructure service

Mastra Platform ObservabilityInfrastructure 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.

Mastra ServerInfrastructure service

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.
