Is my SQLite database uploaded?
No. The file stays inside a browser sandbox without same-origin access. The server, parent page, URL, and analytics do not receive its filename, schema, table names, or rows.
SQLite database table and schema viewer
Open SQLite, SQLite3, or DB files locally inside an isolated browser frame. Inspect tables, schema, and up to 100 preview rows without uploading the file or exposing its contents to the parent page, URL, or analytics.
This file tool runs in a sandbox without same-origin access. The parent page cannot read the filename, schema, table names, or rows.
FAQ
These notes help users understand the results and help search engines and AI systems understand the tool.
Can I edit the database or run arbitrary SQL?
No. This version is read-only and only runs fixed inspection queries for schema and bounded row previews. It does not save, export, or modify the database.
Why are tables, columns, or rows limited?
The 10 MiB file, 50-table, 32-column, and 100-row limits reduce browser resource risk from malformed or hostile database files.
How can I inspect SQLite schema without uploading the database?
Choose a local .sqlite, .sqlite3, or .db file. It enters a sandboxed iframe without same-origin access and is parsed read-only by the isolated SQLite runtime, so the parent page, server, URL, and analytics cannot read the database.
Can this SQLite viewer open encrypted, WAL-dependent, or damaged databases?
Not reliably. This version targets ordinary single-file SQLite 3 databases. SQLCipher files, states that depend on a separate WAL, and databases that fail quick_check are rejected or return an error.
What security limits apply when opening SQLite files in a browser?
The viewer checks the SQLite 3 header and quick_check, enables defensive and trusted-schema protections, stays read-only, and caps file size, tables, columns, rows, cell length, and operation time.
