Pricing
FreemiumCodeium launched with a genuinely free tier for individual developers — unlimited code completions, chat, and search across 70+ languages and 40+ IDEs with no time limit or credit cap. Enterprise plans (custom pricing) added on-premises deployment, SOC 2 compliance, SSO, and zero code retention. After launching the Windsurf Editor in November 2024, the company introduced paid tiers: Free ($0) with unlimited Tab autocomplete and a light agent quota; Pro ($15/month, later raised to $20/month in March 2026) with full model access, standard refreshing agent quota, and Cascade; Teams ($30/user/month); and Enterprise ($60/user/month) with SSO, 1,000 prompt credits, and enhanced security. Following Cognition AI's acquisition and the June 2026 rebrand to Devin Desktop, pricing is now managed under Cognition's Devin plan structure: Free ($0), Pro ($20/month), Max ($200/month), Teams ($80/month + $40/seat), and Enterprise (custom). The codeium.com/pricing URL now redirects to devin.ai/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.

Codeium

Codeium Pros & Cons

Pros

  • Genuinely unlimited free tier for individual developers — no credit limits or trial expiry
  • Broadest IDE coverage of any AI coding tool with 40+ editor integrations at launch
  • Rapid iteration: went from plugin to agentic IDE and $100M ARR in under 3 years
  • Enterprise-grade security with on-prem/VPC deployment, SOC 2, and zero code retention options
  • Cascade/Windsurf Editor introduced flow-aware multi-file agentic coding before competitors
  • Backed by top-tier investors and reached $1.25B unicorn valuation in just 2 years

Cons

  • Rebranded twice (Codeium → Windsurf → Devin Desktop) creating confusion and instability for users
  • Original Codeium extension identity sunset — codeium.com now redirects to Devin/Cognition
  • Pro pricing rose from $15 to $20/month in March 2026, removing its budget pricing edge over Cursor
  • Cascade agent fully retired July 1, 2026 — replaced by Devin Local under new ownership
  • Heavy agentic workflows require Pro plan; free tier agent quota is limited
  • Brand owned by Cognition AI (Devin), not the original Codeium/Windsurf founding team
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
