As I was working on projects with my usual stack with Prisma ORM, my IDE used to lag during every npx prisma generate command. At first, I thought it was just my machine. But after multiple projects—different environments, different databases—the problem remained the same:
Prisma’s code generation step was slowing down my workflow and affecting overall productivity as it uses Rust binary engines.*
This performance issue pushed me to explore alternatives, and that’s when I discovered Drizzle ORM—a lightweight, SQL-first ORM that instantly solved all the bottlenecks I was facing.
🔍 Why Prisma Causes IDE Lag (Especially During prisma generate)
Prisma offers fantastic developer experience—until your schema grows.
Then the lag begins.
Here’s why:
1. npx prisma generate Is Heavy by Design
Prisma doesn’t just generate simple types.
During generation, it creates:
- A full type-safe client
- Deeply nested TypeScript definitions
- Relationship helpers
- Validation layers
- Mappings for the Rust query engine
When your schema gets large, the generated types quickly reach tens or even hundreds of thousands of lines.
Your IDE has to:
- parse them
- type-check them
- index them
- autocomplete them
This causes CPU spikes, lag, and slow reload times.
2. The Prisma Query Engine Adds Overhead
Prisma uses a Rust-based query engine that runs as a separate background binary.
Your IDE and dev environment must interact with this engine constantly.
This leads to:
- slower dev startup
- slower reloads
- slow type generation
- increased RAM usage
Even powerful machines feel this.
3. TypeScript Struggles With Prisma’s Huge Types
Prisma’s generated types are extremely deep and complex.
VSCode and other editors often struggle with:
- intellisense delays
- autocomplete hangs
- slow error reporting
- memory spikes
If you’ve ever typed a Prisma query and waited for IntelliSense, you’ve experienced this.
After dealing with lag long enough, I began looking for an ORM that wouldn’t punish me during development. That search led me to Drizzle ORM.
And the difference was immediate.
Why Drizzle ORM Completely Removed My IDE Lag
Here’s what makes Drizzle dramatically faster:
1. No Code Generation. No Lag.
Unlike Prisma, Drizzle does not run a code generation step.
There is no:
npx prisma generate- huge type output
- Rust binary
- extra engine layer
Drizzle’s types are generated directly from your TypeScript schema.
Your IDE loads them instantly.
No more lag.
No more 100k-line type files.
2. Schema Written Directly in TypeScript
With Drizzle, your database tables are defined using real TS:
export const users = pgTable("users", {
id: serial("id").primaryKey(),
name: varchar("name", { length: 255 })
});
This means:
- your IDE understands everything instantly
- no extra DSL to compile
- no extra build or generate step
- no slowdown as your project grows
Why I Ultimately Switched to Drizzle ORM
After replacing Prisma with Drizzle in a few projects, here’s what I immediately noticed:
- My IDE stopped lagging"# ⚡ Discovering Drizzle ORM: A TypeScript-Native, SQL-First Solution" to a level two heading by using "##"
- TypeScript felt fast again
- No more slow
prisma generate - Queries were clearer and closer to SQL
- Deployments to serverless became trouble-free
- Codebase felt lighter and more maintainable
Drizzle didn’t just improve performance—
it made database work enjoyable again.
Conclusion: If Prisma Is Slowing Your IDE, Drizzle Is the Fix
Prisma is a powerful ORM, but its heavy generation step and complex types can slow down even high-performance machines.
If you’re facing:
- lag during
npx prisma generate - slow autocomplete
- heavy type files
- serverless deployment issues
Drizzle ORM is absolutely worth switching to.
It’s fast, clean, SQL-friendly, and built for modern TypeScript workflows.
Drizzle doesn’t use a query engine.
Your queries compile directly into SQL strings.
Benefits:
- faster execution
- smaller bundle size
- instant serverless support
- no binary processes
This is why Drizzle runs so smoothly in:
- Next.js
- Vercel Edge
- Cloudflare Workers
- Bun / Deno
Prisma often struggles here.
