A Full SQLite Database Editor That Runs Entirely in Your Browser
SQLite is one of those technologies everyone uses but few people really talk about. It quietly powers mobile apps, browsers, desktop software, embedded devices, and countless systems that never get labeled as “enterprise”. Yet, when you actually need to inspect or modify a SQLite database, the workflow often feels oddly old-fashioned: download a tool, install it, open it, load the file, repeat.
That friction is what led me to build Web SQLite Editor.
The idea was simple: what if working with a SQLite database was as easy as opening a web page?
No installs. No servers. No uploads. Just SQLite, running locally, inside the browser.

How it actually works
This tool is not a cloud service and it doesn’t “connect” to your database in any remote way. It uses SQLite compiled to WebAssembly (via sql.js) so the real SQLite engine runs directly in the browser’s memory.
When you open a database file, it never leaves your machine. Nothing is sent anywhere. All queries, updates, triggers, and schema changes are executed locally, just like a desktop application would do — except it happens in a browser tab.
Once you understand that, the security model becomes very straightforward: if you trust SQLite locally, you can trust it here, because it is SQLite.
What you can do with it
The goal was to make the editor genuinely useful, not just a demo.
You can load any existing SQLite database or create a brand-new one in memory. Tables can be inspected, modified, or restructured. Records can be inserted, edited, or deleted using a visual interface that understands both simple and composite primary keys.
You can also run raw SQL queries whenever you need full control, which makes the tool useful not only for editing but also for debugging and learning. Triggers are fully supported too, which is something many lightweight tools ignore, even though triggers are a core part of SQLite.
Performance-wise, the interface is optimized to handle large tables without choking the browser. Rendering is virtualized, so even thousands of rows remain responsive.
Why a browser-based SQLite editor makes sense
A browser is no longer a toy runtime. With WebAssembly, modern JavaScript engines, and decent memory management, it’s perfectly capable of running serious tools.
This editor is especially useful in situations where installing software is inconvenient or impossible: locked-down work machines, quick inspections on someone else’s computer, tablets, Chromebooks, classrooms, or just moments where you want to open a database right now without setting anything up.
It’s not meant to replace full desktop database managers. It’s meant to remove friction when friction is the real problem.
Privacy and trust
One concern always comes up when people see a database editor on a website: “Why would I trust this with my data?”
The answer is simple: you don’t have to trust me — you can trust the code.
The project is fully open source, licensed under MIT, and available on GitHub. There is no backend, no tracking, and no hidden upload logic. If your database ever left your machine, it would be immediately visible in the source.
In fact, the tool can be used offline once loaded.
A quick note about SQLite itself
SQLite is often underestimated because it doesn’t market itself as “enterprise”. But in reality, it is the most widely deployed database engine in the world. It runs inside operating systems, browsers, phones, cars, and devices most people never think about.
Tools that respect SQLite’s simplicity and portability should be just as lightweight — and that philosophy guided this project.
Final thoughts
Web SQLite Editor is intentionally simple, fast, and transparent. It doesn’t ask for an account, doesn’t impose limits, and doesn’t pretend to be more than it is.
It’s a practical tool for developers who value speed, privacy, and control.
If you work with SQLite even occasionally, you might find it surprisingly useful.
