Pricing
FreemiumSupermaven operated a Freemium model during its active life (Feb 2024 – Nov 2025). The Free tier provided fast inline code completions with a 300,000-token context window, compatible with VS Code, JetBrains IDEs, and Neovim — with no trial expiry. Pro was priced at $10/month (or $99/year), unlocking the 1 million token context window, access to Supermaven's largest Babble model, coding style adaptation, and $5/month in Supermaven Chat credits with a 30-day free trial. Team plans were also $10/user/month and added centralized billing and user management for companies. Supermaven was acquired by Cursor in November 2024. All paying subscribers were fully refunded in November 2025 when the standalone product was sunset. Free autocomplete inference was extended for existing Neovim and JetBrains users as a courtesy. The product is no longer available for new signups — Cursor is the recommended migration path.
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.

Supermaven Pros & Cons

Pros

  • Fastest inline code completions of any tool at launch — sub-250ms latency beats Copilot by 3x
  • 1 million token context window gives it codebase-wide awareness without slow retrieval
  • Generous always-free tier with no expiry for solo developers
  • Founded by Tabnine creator — deep domain expertise in efficient code completion models
  • Lightweight extension model — no new IDE required, works inside existing editors
  • Coding style learning personalizes suggestions over time

Cons

  • Product sunset in November 2025 after Cursor acquisition — no longer available for new signups
  • No agentic or multi-file editing capabilities (completions and chat only)
  • Chat credits limited on Pro tier ($5/month) with overage charges
  • Extension API limitations in VS Code/JetBrains constrained more advanced features
  • 7-day code data retention limit on free tier raised some privacy concerns for teams
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
