AI Coding Assistant Comparison Tool

GitHub Copilot, Cursor, Claude Code, and their competitors solve overlapping but distinct problems, and the pricing models behind them have shifted more in the past year than in the previous three combined. This tool compares six current AI coding assistants side by side on price, free-tier availability, IDE support, and what each one actually does best — pick up to three above to see them next to each other.

Key takeaways

• There’s no single “best” AI coding assistant — Cursor and GitHub Copilot lead for in-editor IDE work, Claude Code for autonomous terminal-based refactors, and Tabnine for privacy-critical or air-gapped environments.
• GitHub Copilot moved to usage-based “AI Credits” billing on June 1, 2026 — inline completions stay unlimited on paid plans, but chat, agent mode, and code review now draw from a credit pool.
• Codeium is now Devin Desktop. The product renamed to Windsurf in 2024, was acquired by Cognition (the company behind the Devin coding agent) in mid-2025, and renamed again to Devin Desktop in June 2026 — same editor, same pricing, new name.
• Cursor and Devin Desktop both sit at $20/month for their main paid tier — Cursor for the more mature agentic IDE, Devin Desktop for a lower-friction option with cloud agent handoff built in.
• If you’re on AWS infrastructure, Amazon Q Developer at $19/seat is worth checking before paying more elsewhere — it’s built around the AWS Console and SDLC rather than being a general-purpose assistant.

What this tool does

Select up to three assistants from the dropdowns above to see their pricing, free-tier availability, IDE or environment support, and best-fit use case side by side. The comparison covers current, verified pricing — this is a fast-moving category where plan structures change every few months, so treat this as a snapshot and confirm final numbers on each vendor’s own pricing page before committing a team budget.

How to choose between them

Start with how you actually work, not which tool has the most features. Three questions narrow the field fast:

• Do you want AI inside your current editor, or a new editor built around AI? GitHub Copilot, Amazon Q, and Tabnine are plugins that add AI to VS Code, JetBrains, and similar. Cursor and Devin Desktop are standalone editors (both VS Code forks) built with AI as the default interaction model, not an add-on.
• Do you need a terminal agent or an in-editor one? Claude Code runs in the command line and works alongside whatever editor you already use — it’s built for autonomous, multi-step tasks rather than line-by-line completion.
• Does data residency or on-prem deployment matter? If your organization needs code to never leave your network, Tabnine is the only tool here with a genuine on-premises deployment option.

Most senior developers end up running two tools rather than one — a low-cost daily-driver like GitHub Copilot or Amazon Q for routine completions, paired with Claude Code or Cursor for the harder multi-file or multi-step work. Budget for the pairing, not just a single subscription, if your team does both kinds of work regularly.

Frequently asked questions

Is GitHub Copilot or Cursor better for most developers?

Copilot is the lower-friction, lower-cost starting point — wider IDE support and a real free tier. Cursor costs twice as much at the entry tier but is built specifically for agentic, multi-file work; if most of your day is autocomplete-style suggestions, Copilot covers it, but if you’re regularly asking an assistant to plan and execute changes across several files, Cursor’s editor is built for that in a way a plugin isn’t.

What happened to Codeium and Windsurf?

Codeium rebranded to Windsurf in 2024, was acquired by Cognition (maker of the Devin autonomous coding agent) in July 2025, and was renamed again to Devin Desktop in June 2026. It’s the same editor with the same plans and pricing carried forward — if you see “Codeium” or “Windsurf” referenced elsewhere, that’s the same product under an earlier name.

Can I use more than one of these at the same time?

Yes, and it’s common — these tools don’t conflict with each other since they’re either editor plugins or separate standalone applications. A frequent setup is a cheaper completion-focused tool for daily typing, paired with a more expensive agentic tool reserved for genuinely complex tasks, which controls cost better than putting everything on the more expensive tool by default.

Does a free tier actually work for real projects, or is it just a trial?

It depends on the tool. Devin Desktop’s free tier is genuinely free-forever with no credit card, and usable for real if limited work. GitHub Copilot’s free tier (2,000 completions/month) is workable for light, occasional use but tight for daily professional work. Cursor’s free tier is closer to a trial — enough to evaluate the product, not enough to finish a real feature without hitting limits.

Why do GitHub Copilot and Amazon Q both cost about $19-20 for teams, but individual pricing differs so much?

Team and individual pricing are usually set independently — team tiers bundle in admin controls, IP indemnity, and centralized billing that individual plans don’t need, so vendors price them on a separate basis. Amazon Q’s $19 individual Pro price happens to land close to Copilot’s $19 Business seat price, but that’s coincidental positioning, not a sign the products are equivalent at those tiers.
