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.
PaidTabnine offers two enterprise plans on annual subscriptions. The Code Assistant Platform is $39/user/month and includes AI code completions, IDE chat (Claude, GPT, Gemini, Meta, Mistral), Jira integration, flexible deployment (SaaS/VPC/on-prem/air-gapped), zero code retention, SSO, IP indemnification, provenance tracking, centralized admin analytics, RBAC, and priority support. The Tabnine Agentic Platform is $59/user/month and adds the Enterprise Context Engine (unlimited connections to GitHub, GitLab, Bitbucket, Perforce P4, Jira, Confluence), autonomous agentic workflows, MCP tool integrations (Git, Jira, Confluence, Docker, package managers, CI/CD), the Tabnine CLI agent, and governance controls for MCP and per-user pricing thresholds. Headless CI/CD agents are an optional add-on. When using Tabnine-provided LLM access, token consumption is billed at actual LLM provider prices + 5% handling fee. Unlimited usage is included when using your own on-premises or self-managed cloud LLM endpoint. No self-serve trial; all plans require a sales demo.

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
Tabnine

Tabnine Pros & Cons

Pros

  • The original AI coding assistant with 8+ years of enterprise production experience and the most mature platform in the category
  • Only AI coding tool offering fully air-gapped deployment with zero code retention — critical for defense, healthcare, finance, and government
  • IP indemnification with provenance and attribution — every suggestion is traceable to its training source for full license compliance
  • Enterprise Context Engine builds a live organizational knowledge graph enabling true system-level AI reasoning beyond document retrieval
  • Multi-LLM flexibility — choose Claude, GPT, Gemini, Meta, Mistral, or your own on-premises LLM with no vendor lock-in
  • Gartner Magic Quadrant Visionary 2025 and InfoWorld Technology of the Year 2025; trusted by Samsung, Ericsson, Raytheon, and GE Healthcare

Cons

  • Acquired by Tricentis on July 30, 2026 — product roadmap and pricing continuity depend on new ownership direction
  • No free individual tier as of 2026 — pricing starts at $39/user/month (Code Assistant) or $59/user/month (Agentic Platform) on annual contracts
  • Higher price point than GitHub Copilot ($19/user/month) and Cursor ($20/user/month) for teams that don't need enterprise-grade security or air-gapping
  • Enterprise Context Engine requires onboarding time to index and structure large codebases before reaching full accuracy
  • Smaller developer community mindshare than GitHub Copilot or Cursor — fewer third-party tutorials and integrations
