What ExtendsClass SQLite Browser is
ExtendsClass SQLite Browser is a free web tool for creating, opening, querying, editing, and exporting SQLite database files. It runs entirely in the browser through sql.js, so occasional users can work without installing a desktop client. The table interface lets you browse and sort rows, insert or delete records, and change cell values. CSV or TSV files can be imported into SQLite tables, while table contents and SQL query results can be exported to CSV. Queries run in the editor, and entered SQL is retained in a local browser backup that may be deleted at any time. Databases and their queries can be saved on the maker’s server for sharing, with an approximate 2 MB database limit. Shared saved data is accessible to everyone, so sensitive information should not be stored there. The tool does not include the SpatiaLite extension. It is aimed at developers testing or debugging database files and non-developers editing data such as browser bookmarks.
Who it suits
It suits developers who need browser-based SQLite testing or debugging, and people editing SQLite files occasionally. Users needing everyday database work may prefer a desktop client.
