SQLite3 Online Viewer

Provides a browser-based SQLite3 viewer to open and explore SQLite database files without local installation. Target users include developers, DBAs, data analysts, and educators who need quick data inspection, schema browsing, and ad-hoc querying in a secure, isolated environment. The tool accepts .sqlite/.db files or pasted SQL and returns results, schema summaries, and export options. All operations run in the browser.
How it works: the in-browser engine executes SQL against the loaded database in a sandbox, ensuring data never leaves the user's device. Inputs are validated: database file must be valid SQLite, SQL statements are checked for syntax, and results are formatted in tables. Outputs include tabular results, CSV/JSON exports, and a textual schema dump. Practical use cases include data validation, defect reproduction, and teaching SQL.
Core differentiators: client-side execution, no server required, instant feedback, multi-database support, query history, and export versatility. Optional features include query hints, explain plan for SQLite, and advanced filtering of results. Common workflows: upload a database, run a query like SELECT * FROM users WHERE status='active' LIMIT 100, inspect columns, export to CSV, share results with teammates.
Security and privacy: since all data remains in the browser, there is no data transmission unless the user chooses to export or copy. Target audiences: developers, QA, data science students, educators. Real-world scenarios: verify sample datasets, debug problematic queries, teach joins and aggregations.
