sqlime
Sqlime is a free, browser-based SQLite playground for writing, debugging, and sharing SQL queries. It runs entirely in the browser with no server backend, supports loading external SQLite databases, and can save/share work via GitHub gists.

What sqlime is
A JavaScript-based web application powered by sqlean.js (SQLite compiled to WebAssembly), offering full SQL support including indexes, triggers, views, CTEs, and window functions. Stores databases as SQL dumps and integrates optional OpenAI for query assistance.

Best use cases
Implementation considerations
- Browser storage is ephemeral; users must explicitly save to GitHub gists to persist work across sessions.
- OpenAI integration is optional and requires users to provide their own API credentials; no built-in API quota management.
- SQLite's in-memory execution may encounter timeout or memory limits with large queries; no server-side fallback.
- Relies on GitHub for persistence and sharing; requires a GitHub account for collaborative features.
- No built-in role-based access control; sharing relies on GitHub gist privacy settings.
When to avoid it — and what to weigh
- Large Datasets or Performance Testing — Browser-based execution is not suitable for analyzing gigabytes of data or conducting production-grade performance benchmarks. In-memory constraints apply.
- Production Data Processing — Not designed for handling sensitive or production data at scale. No audit logging, no server-side access controls, and browser persistence is unpredictable.
- Complex Multi-User Workflows — Lacks user management, role-based access, or concurrent editing. Each session is isolated to the browser; not suitable for team-based database administration.
- Persistent, Reliable Data Storage — Data lives only in the browser's local storage or as GitHub gists. No guarantees of long-term persistence or recovery; not a backup or archival system.

No server means no server-side compromise; data processing is local to the browser. GitHub and OpenAI credentials are stored locally in the browser (not on Sqlime's servers). Risks: browser local storage can be accessed by other scripts if XSS occurs; sharing via GitHub gist visibility depends on user configuration; OpenAI API keys must be handled carefully. CORS policy applies when loading external databases. No formal security audit or vulnerability disclosure process documented.
Alternatives to consider
SQLPad
Full-featured, server-based SQL IDE with user management, query history, and multi-database support. Better for teams and production workflows, but requires deployment and infrastructure.
DBeaver Web
Browser-based database client supporting SQLite and other engines. Offers more administrative features and connection management, though heavier and less minimalist.
Replit / Gitpod (with SQLite)
General-purpose cloud development environments; can run SQLite and SQL playgrounds with broader language support. Overkill for SQL-only use cases but enables more complex workflows.
