Most developers should start with Codeium. It’s free, it’s good, and it tells you whether you actually need what Cursor offers — before you pay $20/mo to find out.
Start here — everyone

Upgrade only if you hit the ceiling
When you need full codebase indexing or Agent mode — features Codeium doesn’t have at any price.

Codeium earns the upgrade to Cursor by proving you need what Cursor specifically offers.
How we score → All coding tools →Codeium free is not a compromise — it's a genuinely good tool. Unlimited completions, 40+ editors, JetBrains support, no credit card. For most developers evaluating AI coding tools for the first time, Codeium is the correct first step. Not a stepping stone — potentially the destination.
Cursor AI Pro wins on capability in VS Code. Full codebase indexing means your completions and chat understand your entire project — not just the file you have open. Agent mode executes multi-file changes from a plain English description. These are real, daily-use advantages that Codeium doesn’t have. But they cost $20/mo, and you should know whether you need them before paying.
“Run Codeium free for two weeks on a real project. If you never hit a wall, you’re done. If codebase context becomes a daily frustration, that’s when Cursor Pro earns its $20/mo.”
Use Cursor AI when... - →You use VS Code daily and need AI that understands your entire project — not just the current file
- →You want Agent mode — describe a multi-file refactor in plain English and have it executed automatically
- →You’ve tried Codeium for two weeks and found completion-only AI too limited for your workflow
- →$20/mo would save you 2+ hours per week — a clear ROI at any reasonable developer rate
Use Codeium when... - →You want unlimited AI code completion at $0 — no trial, no cap, no card required
- →You use JetBrains — Codeium fully supports IntelliJ, PyCharm, WebStorm, GoLand, and Rider
- →You work across multiple editors and need one AI tool that covers all of them
- →You’re evaluating AI coding tools for the first time and want to establish a baseline before paying
Codeium Pro ($12/mo) sits between both options — faster completions, priority support, and more model access. If Codeium free is working but you want more, it’s worth considering before jumping to Cursor Pro at $20/mo. See the paid plan breakdown in S8.
Category by category.
Price — free vs $20/mo
Codeium free is $0 — genuinely, permanently, no credit card. Cursor Pro is $20/mo. That gap only makes sense if you’re getting $20/mo worth of value from the features Codeium doesn’t have. Codeium also offers a Pro plan at $12/mo, which closes the gap further if you want enhanced features without the full Cursor price.
Codebase indexing
Cursor Pro indexes your entire codebase and uses that context for every completion and chat query. On a large project, this means suggestions that reference patterns from files you didn’t have open. Codeium works from your current file and open tabs only. For small projects this difference is minimal. For large codebases, Cursor’s edge is meaningful every day.
Agent mode
Cursor’s Agent mode lets you describe a change in plain English — “add input validation to all API endpoints” — and have it plan, map, and execute the change across multiple files. Codeium has no equivalent. If you never need this, that’s fine — you don’t need Cursor. If you do need it, Codeium can’t replace it.
Editor compatibility
Codeium works in 40+ editors including all JetBrains IDEs, Neovim, Emacs, and more. Cursor is VS Code — full stop. If your editor isn’t VS Code, Cursor is not an option. This isn’t a minor difference; it’s a binary one.
Completion quality
Both produce strong completions. Cursor’s advantage is context — on a large project, completions reference patterns from your actual codebase rather than generic patterns. Codeium’s completions are very good and noticeably better than nothing. The gap between them is smaller than the gap between either and having no AI assistance at all.
Privacy and deployment
Codeium offers enterprise self-hosting — your code never leaves your infrastructure. This is a serious advantage for teams in regulated industries or with strict data policies. Cursor has a privacy mode but no self-hosting option. For individuals this rarely matters; for enterprise teams it can be the deciding factor.

Cursor AI
The right choice if you use VS Code heavily every day and have validated that you need codebase indexing or Agent mode. $20/mo is justified if it saves 2+ hours per week. Don’t start here — start with Codeium and upgrade when you hit the ceiling. Read the full Cursor AI review →
Codeium
The correct starting point for almost everyone. Unlimited completions at $0, JetBrains support, 40+ editors, no cap. Use it until you know exactly what’s missing — then decide whether that’s worth $20/mo. For many developers it won’t be. Read the full Codeium review →
Also worth knowing: GitHub Copilot sits between both — $10/mo, strong JetBrains support, GitHub integration. If Codeium free isn’t enough but Cursor feels like too much, Copilot Individual is worth considering. See all options in our AI Coding Tools comparison.
When to pay.
And when not to.
Start with Codeium free. It costs nothing and covers most use cases. Only pay when you know exactly what you’re paying for.
Decision logic: VS Code + need codebase indexing or Agent mode = Cursor Pro at $20/mo. Want faster Codeium without Cursor’s features = Codeium Pro at $12/mo. Not sure yet = Codeium free at $0.
