Hi everyone!
I'm a teacher, and in my SQL classes, I've always felt that many online tools are either too "heavy," full of distractions, or have some cost/signup friction that gets in the way of a beginner's first steps.
Students just want to write their first CREATE TABLE and see the results instantly. They don't want to manage servers or deal with bloated interfaces.
That's why I decided to build a simple, lightweight SQLite Playground.
The Motivation: Focus on Learning
My main goal was to provide a didactic and 100% free tool for students. I wanted an environment where:
- No Setup is Required: You just open the link and start typing.
-
Privacy is Guaranteed: The database runs entirely in the browser via
WASM. No data ever leaves the user's computer. - Visual Feedback: It has a built-in Database Explorer so learners can actually see the schema they are building in real-time.
The Tech Stack
Being a dev-to-dev community, here is what’s under the hood:
- Vue 3 + Vite + TypeScript
- SQLite WASM: To run the database engine client-side.
- Monaco Editor: For that professional IDE feel.
- Local Storage: To remember your SQL and preferences (like if you prefer the explorer hidden or visible).
I need your feedback!
I’m providing this as a free educational tool, and I’d honestly love to hear from this community.
- Any missing functionality in this beta?
- How is the performance on your end?
- Any UI/UX tweaks that would make it easier for an absolute beginner? You can try it here: fasttools.dev/sql-playground
I'm building this as part of a larger project called FastTools, which focuses on fast, private, browser-native utilities.
Any feedback, critique, or suggestion is more than welcome!
