Pricing Model
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.
FreemiumRefact.ai is free to start with 2,000 agent/chat coins per month — no credit card required. This covers basic AI Agent and chat usage with access to the platform's full feature set within the monthly quota. Pro costs $10/month (or $8/month billed annually) and provides a higher coin allocation for developers who use the AI Agent and chat heavily on a daily basis. Enterprise pricing is custom and covers three deployment models: self-hosted on your own GPU infrastructure (any hardware you own or rent), AWS-managed (including AWS Inferentia2 for 1.5x price-performance), and VPC/cloud-managed SaaS. Enterprise adds dedicated engineer support, fine-tuning on your private codebase, code access restriction controls, team management dashboard, and SLA guarantees. Contact hello@refact.ai for enterprise pricing.

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

Refact.ai Pros & Cons

Pros

  • #1 on SWE-bench Lite for open-source AI coding agents — independently validated autonomous task completion performance
  • Self-hosted on any hardware including AWS Inferentia2 — first AI coding assistant on Inferentia2 with 1.5x price-performance vs GPU
  • Fine-tuning on private codebase delivers ~45% code acceptance rate — significantly higher than generic completions
  • Open source with full transparency — audit the model, the agent code, and the inference pipeline
  • Supports both open-source LLMs (Code Llama, DeepSeek, Llama) and closed-source models (GPT-4, Claude) in self-hosted mode
  • Free plan with 2,000 coins/month and no credit card — genuinely usable for individual developers and evaluation

Cons

  • Smaller community and brand recognition than GitHub Copilot, Cursor, or Codeium
  • Self-hosted deployment requires GPU hardware and technical infrastructure setup — not trivial for smaller teams
  • Agent mode still maturing compared to more established alternatives like Cursor or Cline
  • Cloud-hosted tier is newer and has fewer enterprise features than established alternatives like Tabnine or Augment Code
  • Visual Studio extension is in beta — not as polished as the VS Code and JetBrains plugins
  • Fine-tuning pipeline requires dedicated setup and data preparation — significant upfront investment for enterprise customization
