Production-ready Windsurf rules for frontend devs, SaaS founders, backend engineers, and 8+ more roles. Built by AI power users who live in Windsurf daily. Updated monthly as Windsurf evolves.
Every developer who installs Windsurf faces the same friction: the default AI behavior is generic, and creating a proper .windsurfrules file from scratch takes longer than the first project milestone. Most devs never write one at all.
Without a strong .windsurfrules file, Windsurf's Cascade AI keeps making generic assumptions — suggesting patterns that don't fit your architecture, missing your team's naming conventions, and generating scaffolding you immediately rewrite.
You type the same context into every Cascade chat: "I use Next.js, TypeScript, Prisma, deployed on Railway..." A good .windsurfrules file encodes this once and persists it across every session. Most developers never write one.
Windsurf's rules file uses YAML front matter plus markdown sections — a different format from Cursor. If the YAML is malformed or the section headers are off, Cascade silently ignores your rules. Hours of context, silently dropped.
Instead of starting from a blank file and guessing at the right YAML structure, you start from a template engineered by developers who have pushed Windsurf's Cascade to its limits. Drop it in. Customize three fields. Your Windsurf session immediately understands who you are, what you're building, and how you write code.
Every template uses Windsurf's proper YAML front matter format with description, globs, and alwaysApply fields — no guessing, no silent parse failures, no wasted context.
Each template is built for a specific engineering role. The frontend template encodes component architecture and CSS-in-JS conventions. The SaaS template covers multi-tenancy patterns and billing edge cases. Generic rules don't change Cascade's behavior — role-specific ones do.
Windsurf ships changes to its rules format and Cascade capabilities regularly. Brainfile Pro subscribers get updated templates automatically. Your .windsurfrules file never falls behind the editor it's supposed to be controlling.
Each template encodes the conventions, patterns, and guardrails that matter most for that engineering role. Not generic rules — specific instructions that change how Windsurf's Cascade behaves in your codebase.
No YAML front matter to figure out. No trial and error with rule syntax. Pick your role, drop in three lines of stack context, and Windsurf's Cascade immediately understands how you build.
Browse the library and select the template that matches how you actually work. Frontend, backend, SaaS, DevOps, mobile, AI/ML, security, or full-stack — every role has a template engineered by developers who live in that stack.
→Fill in your framework, your database, and your deploy target in the YAML front matter. The template pre-fills all conventions, patterns, and guardrails based on what engineers in your role actually care about. Total time: under five minutes.
→Save as .windsurfrules in your project root. Windsurf reads it automatically on every Cascade session. No extra config, no API keys, no restart required.
Writing a great .windsurfrules file from scratch is a 2–4 hour project the first time — and an ongoing maintenance burden after that. Here's how Brainfile compares.
| Category | ✦ Brainfile Pro | Write your own |
|---|---|---|
| Time to set up | 5 minutes — pick template, fill in 3 stack fields, drop into project root | 2–4 hours — research YAML format, write rules, test with Cascade, iterate |
| YAML syntax correctness | Pre-validated front matter — description, globs, alwaysApply fields correct by default | One typo in YAML silently breaks your entire rules file with no error message |
| Template quality | Expert-engineered by AI power users with 1,000+ hours in Windsurf and Cascade | Trial and error — most homemade rules miss the edge cases that matter in daily use |
| Monthly updates | Yes — templates updated as Windsurf's rule format and Cascade capabilities evolve | Manual — you research and rewrite yourself every time Windsurf ships a major update |
| Role coverage | 8+ specialized roles — frontend, backend, SaaS, DevOps, mobile, AI/ML, security, full-stack | Your one role — any additional templates require hours more research and writing |
| Windsurf version sync | Automatic — Pro subscribers receive updated templates on every major Windsurf release | Manual — stale rules silently degrade Cascade's output quality with no warning |
| Team sharing | Commit .windsurfrules to git — every engineer on your team works from the same baseline | Possible, but ad-hoc rules without peer review drift and contradict each other over time |
| Works alongside .cursorrules | Yes — Brainfile covers both Windsurf (.windsurfrules) and Cursor (.cursorrules) with one subscription | You'd need to research and write two completely separate rule sets from scratch |
| Support | Active support + template request forum for Pro and Enterprise subscribers | GitHub issues and documentation — no dedicated help when Cascade ignores your rules |
Windsurf is not just a re-skinned Cursor. Cascade operates differently from Cursor's AI, and the rules format reflects that. Brainfile's Windsurf templates are built from the ground up for Windsurf — not ported from .cursorrules files.
Windsurf's .windsurfrules file requires YAML front matter with description, globs, and alwaysApply fields before the markdown content. Get this wrong and Cascade silently ignores your entire file. Every Brainfile template has this correct out of the box.
Windsurf's Cascade is an agentic AI that takes multi-step actions — it's not just autocomplete. The instructions that work for Cascade need to specify not just how to write code but how to sequence tasks, when to ask before acting, and how to handle partial completions. Brainfile templates account for this.
Most developers use more than one AI coding tool. Brainfile Pro includes templates for Windsurf (.windsurfrules), Cursor (.cursorrules), and Claude Code (CLAUDE.md). When you switch between tools — or run them together — every tool knows exactly how you code.
