Codeium's agentic IDE that predicts your next steps and works as an intelligent pair programmer.
Windsurf (formerly Codeium) is an AI-first code editor whose headline feature is Cascade — an agent that reads your codebase, plans multi-step changes, and executes them across files from a plain-language description. It is the most direct competitor to Cursor: both are VS Code-style AI editors built around a powerful multi-file agent, and choosing between them is one of the more common decisions developers face in 2026.
Windsurf went through a significant pricing overhaul on March 19, 2026, retiring its credit-based system in favor of daily and weekly quotas, and raising Pro from $15 to $20/mo. The Free tier includes unlimited Tab autocomplete (which never touches quota) plus a light daily/weekly quota for Cascade and Chat — in practice good for two to three days of real coding per period before the quota runs dry. Pro ($20/mo) and Max ($200/mo) raise those quotas substantially.
Its strengths are a genuinely strong agent and a clean, fast editor. Cascade's plan-then-execute flow is well regarded, the editor is responsive, and because it is VS Code-based, migration is painless. For developers who want Cursor-style agentic editing, Windsurf is the main alternative and is often slightly cheaper at the Pro tier.
The honest weaknesses: the free quota is genuinely tight — two or three days of real use and you are blocked until it resets, which pushes serious users to pay quickly. The 2026 switch from credits to quotas was disruptive for existing users, and the product's identity has shifted repeatedly (Codeium → Windsurf, credits → quotas). For most developers the practical question is simply Windsurf vs Cursor; they are close enough that pricing, quota feel, and personal preference decide it. See Cursor vs Windsurf.
Who it is for: developers who want a strong, affordable agentic AI editor and prefer Windsurf's Cascade flow or pricing. Who it is not for: anyone who needs heavy daily agent use on the free tier (the quota is too tight), or developers already happy in Cursor with no reason to switch.
Cascade is Windsurf's core: describe a change in plain language and it reads the codebase, builds a step-by-step plan, and executes across files. For refactors and feature work that span multiple files, this plan-then-do flow is its main draw.
Windsurf's Tab autocomplete is unlimited even on the free tier and never consumes quota. Developers who mainly want fast, AI-powered completions — without heavy agent use — can run on Free indefinitely for that specific workflow.
Because Windsurf is VS Code-based, developers move over with their extensions and settings intact. Those evaluating Cursor alternatives use it as a near drop-in to compare Cascade against Cursor's agent on their own codebase.
After the March 19, 2026 overhaul, Windsurf offers Free ($0, unlimited Tab autocomplete plus a light daily/weekly quota for Cascade and Chat), Pro ($20/mo, up from $15), Max ($200/mo), Teams ($40/user/mo), and Enterprise (custom), with 17–20% off on annual billing. The big change: the old credit system was retired in favor of daily and weekly quotas. The trap to know: the free quota realistically lasts only two to three days of active coding before it runs dry, so anyone using the agent seriously will need Pro quickly — Tab autocomplete is the only truly unlimited free feature.
They are very close — both are VS Code-style AI editors built around a strong multi-file agent (Cascade for Windsurf, Composer for Cursor). Windsurf is often slightly cheaper at Pro and some prefer Cascade's plan-then-execute flow. The honest answer is that the decision usually comes down to pricing feel and personal preference.

Codeium rebranded to Windsurf in late 2024, evolving from a pure autocomplete extension into a full AI code editor. If you used Codeium previously, Windsurf is its direct continuation with a much larger feature set centered on the Cascade agent.
Tab autocomplete is unlimited and free forever, but Cascade and Chat run on a light daily/weekly quota that, in practice, lasts only two to three days of real coding before resetting. Serious agent users will need Pro ($20/mo) to avoid constantly hitting the quota.
On March 19, 2026, Windsurf retired its credit-based billing and replaced it with daily and weekly quotas, and raised Pro from $15 to $20/mo. This makes usage more predictable per period but removed the flexibility of carrying credits.
Cascade is Windsurf's agentic feature — the equivalent of Cursor's Composer. You describe what you want in plain language and Cascade reads your codebase, builds a step-by-step plan, and executes the changes across files, which you then review.
