Pricing
FreemiumJunie uses JetBrains' AI credit system where 1 AI Credit ≈ $1 USD. Credits are shared between JetBrains AI Assistant and Junie. Since August 2025, credits reflect actual per-token costs at provider rates. The AI Pro plan costs approximately $100/year and includes a basic monthly credit quota suitable for occasional Junie use plus full JetBrains AI Assistant access. The AI Ultimate plan at approximately $200/year includes a larger credit quota recommended for regular Junie agentic workflows. Both plans can be topped up with additional credits at any time, which remain valid for 12 months. Junie also supports BYOK (Bring Your Own Key) at provider-rate pricing with zero JetBrains markup — providing full model access at the lowest possible cost for developers who want to control their LLM spend. The Junie CLI free access includes 5 AI credits for a real first task. JetBrains AI Enterprise adds Junie with a large quota, advanced user management, and SSO for organizations.
FreemiumJetBrains AI offers four tiers. AI Free is $0/month with 3 AI credits every 30 days, unlimited code completion via JetBrains' Mellum model, and local model support via Ollama or LM Studio, but excludes frontier models and Junie for sustained agentic work. AI Pro is $10/month (Individual) or $20/month (Business), with 10 AI credits per month. AI Ultimate is $30/month (Individual) or $60/month (Business), with 35 AI credits per month, including a $5 bonus over the plan price. AI Enterprise is custom-priced at roughly $60/user/month billed annually, adding organization-wide credit pooling and enterprise controls. Each AI Credit equals $1 USD, and unused top-up credits (purchased separately at $1 each) remain valid for 12 months, while unused monthly plan credits do not roll over. A 30-day AI Pro trial is available for new users. AI Pro is also bundled into JetBrains' All Products Pack and dotUltimate subscriptions.

JetBrains' AI coding agent — #1 on SWE-Rebench, plans before it codes
AI coding assistance built natively into every JetBrains IDE
Junie

Junie Pros & Cons

Pros

  • #1 on SWE-Rebench at 61.6% resolved — independently validated as the top-performing coding agent harness with fresh benchmark tasks
  • Structured plan-first approach prevents unintended changes — you review and approve the plan before the agent writes a single line
  • Native JetBrains integration — not a ported VS Code extension; Junie uses the full JetBrains SDK for tests, debuggers, local servers, and project-aware refactoring
  • Junie CLI (March 2026) extends the same agent to any IDE, terminal, CI/CD, GitHub, and GitLab with BYOK at zero markup
  • Model flexibility with cost optimization — plan on powerful models, implement on fast/cheap models, saving significant credit costs on complex tasks
  • From JetBrains — the company with 15M+ developer users and 30 years of IDE expertise; strongest enterprise trust signal in the JetBrains ecosystem

Cons

  • Credit-based pricing is complex and can be expensive for heavy agentic workflows — agentic tasks consume many internal model calls, draining credits faster than expected
  • Requires an active JetBrains IDE subscription to access the full Junie plugin (though Junie CLI is standalone)
  • Credits shared between Junie and AI Assistant — heavy AI Assistant users may exhaust quotas before using Junie
  • Junie CLI is still in Beta as of mid-2026 — some features like ACP mode and advanced IDE integration are still being refined
  • No permanently free tier for commercial use beyond the 5-credit trial — BYOK is the best option for cost-sensitive developers
  • Credit pricing is per-token and varies by model, making monthly costs hard to predict for variable workloads
JetBrains AI Assistant

JetBrains AI Assistant Pros & Cons

Pros

  • Deep semantic project understanding via IntelliJ's existing static-analysis engine, not just open-file context
  • Junie autonomous agent handles multi-file planning, implementation, and self-correction, including a dedicated Debug mode
  • Works across a single subscription spanning 20+ JetBrains IDEs
  • Supports local models via Ollama and LM Studio at zero credit cost
  • Strong enterprise trust features including zero-data-retention policies and .aiignore support

Cons

  • Locked into the JetBrains IDE ecosystem, so it offers no value for developers using VS Code or other editors
  • Credit-based quota system can be confusing, and heavy Junie or Claude Agent use can exhaust monthly credits well before the billing period ends
  • AI Pro's 10 monthly credits are reportedly consumed within about a week under heavy agentic use, pushing users toward costly top-ups ($1 per credit)
  • Best suited to JVM languages (Java, Kotlin); completion quality is reportedly less consistent for other languages
  • AI Free tier excludes frontier models and the Junie agent, limiting it mostly to a demo of completion features
