Windsurf

Freemium

4.0

AI code editor by Codeium built around the Cascade agent architecture, where the AI maintains a persistent understanding of your entire coding session rather than responding to isolated prompts. Cascade can plan and execute multi-step tasks while the developer continues working, with "flows" that track intent across file edits, terminal commands, and test results. Priced at $15–30/mo as a direct Cursor competitor.

Category:AI Coding

Features

Cascade agent with persistent session context across files, terminal, and tests
Flows: continuous AI task tracking that persists through developer interruptions
Windsurf Tab: context-aware multi-line code completion with cross-file awareness
Inline editing with natural language instructions on selected code
Built-in terminal with AI command suggestions and error explanations
+3 more

Pros

Cascade's session persistence means you can pause a multi-hour task and resume without losing AI context
Freemium tier is more generous than Cursor — 5 Cascade flows per day at no cost
Codeium autocomplete is lightweight and fast, consuming fewer resources than Copilot on low-RAM machines
Flows architecture is better suited to iterative feature development than one-shot Composer-style prompts

Cons

Smaller user base than Cursor (estimated 200K vs 1M+) means fewer community resources and extensions
Cascade can lose track of intent in flows longer than ~2 hours, requiring a manual context reset
No JetBrains support as of Q1 2026 — VS Code-based only
Pro plan ($15/mo) limits Cascade flows to 30/month; $30/mo for 90 flows
Codeium's model quality trails Claude and GPT-4o on complex reasoning tasks in the AI chat
