JetBrains
AI agent
Coding agent from JetBrains that plans, implements and tests changes from the terminal, an IDE, GitHub or GitLab, with human-in-the-loop approval and a choice of underlying model.
Agent platform
Organisation layer for AI coding tools, formerly JetBrains Central: grants access to models and agents per team or person, sets AI spending limits, manages company-wide provider keys and MCP servers, and reports which tools are used where.
Developer tool
Cloud semantic index of a codebase that coding agents query instead of searching file by file: it keeps repositories indexed incrementally, answers code questions across several organisation repos, and plugs into Claude Code, Codex CLI and Junie CLI.
Command-line launcher, formerly JetBrains Central CLI, that runs terminal coding agents such as Claude Code, Codex and Junie CLI under one JetBrains account, paying for them with JetBrains AI credits while access, agents and models are governed centrally.
Free IDE plugin that runs several coding agents (Junie, Claude Agent, Codex, Copilot or any ACP agent) side by side across projects, tracks their sessions and changed files, and lets the developer review each diff with the IDE's own code intelligence.
In-IDE AI assistance across JetBrains' IDEs — chat, code completion and agent-driven workflows — plus governance controls for teams, sold as a subscription shared with Junie.
Mastra
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.
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
JetBrains sells these in a stack layer with no product recorded for Mastra yet — nothing on the other side to compare them against.
Application
Desktop app for macOS, Windows and Linux that analyses local CSV and Excel business exports in plain language and produces reports in which every figure can be traced to its source rows, filters and calculation, using a hosted model provider the user brings or a local model.
AI assistant inside Datalore notebooks that turns a request into Python, SQL or R code or Markdown text using the notebook's earlier analysis as context, proposes fixes for failing cells as a reviewable diff, and suggests next analysis steps toward a stated research goal.
AI writing companion for people in tech, delivered as a browser extension and a JetBrains IDE plugin, that proofreads grammar, spelling and style and offers inline completion, rephrasing and tone changes, summaries, translation and an AI chat in commit messages, docs, Jira, Slack and Gmail.

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.
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.
