Amp vs Junie (2026)

Amp

by Amp Frontier Corporation

Junie

by JetBrains

Pros

• ✓Each thread can run in a cloud orb set up with the project's code, tools and plugins, so agents keep working after the laptop closes, and threads can be started or followed from the web, Mac, iPhone or the CLI.
• ✓Multi-model by design: four modes route work across OpenAI, Anthropic and fast models, and on Hobby, Individual and Teams developers can bring a ChatGPT subscription or their own keys with no Amp token fees.
• ✓Team features come at no extra charge, including shared threads, multiplayer, shared portals, plugins and skills and pooled credits, and a GitHub App lets agents open pull requests and read CI status.

Limitations

• ⚠Model usage beyond a tier's included credits is paid separately, through the developer's own provider subscription or keys or through Amp credits at provider API prices, and purchased credits expire after twelve months.
• ⚠Paid tiers are billed monthly and orb time is metered by the minute: Megawatt's 45,000 minutes go faster on larger orbs, and the largest orb size is limited to Gigawatt and Enterprise.
• ⚠SCIM, audit logs, IP allowlisting and regional endpoints are on the quote-based Enterprise tier, and SAML or OIDC SSO needs at least one workspace member on a paid tier.

Pros

• ✓Runs in the terminal on Linux, macOS and Windows, inside JetBrains IDEs and Android Studio, and in CI through a GitHub Action and GitLab CI/CD.
• ✓Works with any model: JetBrains AI cloud models, bring-your-own-key from OpenAI, Anthropic, Google, xAI, OpenRouter or GitHub Copilot, and local models.
• ✓Plan mode writes an editable plan before coding, and in JetBrains IDEs Junie can drive the debugger and inspect runtime state.

Limitations

• ⚠The free start includes 5 AI credits, and cloud use beyond them needs a JetBrains AI plan, a Junie API key or the developer's own provider keys.
• ⚠Junie Local requires an Apple Silicon M5 Mac with macOS 26 or later and 64 GB of RAM, and runs one fixed Qwen3.6-27B model for now.
• ⚠Remote mode needs a JetBrains Account or Junie API key sign-in, and is not available through JetBrains AI Enterprise.
