A .db3 file is typically a SQLite database in a single file. SQLite even flies - Airbus uses it in the flight software of the A350 airliner, where the code is tested to aviation-grade standards. SQLite, which .db3 files use, keeps an entire database in one cross-platform file with no server process required. Its author dedicated the code to the public domain and even refuses patches from contributors who will not do the same.

How do I open a .DB3 file?

Drop a .DB3 file onto Analyser at https://analyser.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. Open SQLite databases (.sqlite/.db/.sqlite3) and read their full schema in-browser - every table with its columns and row counts, views, indexes, triggers, the CREATE-statement DDL, and a sample of the largest table. Reads the WAL-mode sidecars too: the Write-Ahead Log (-wal) - page size, salts, frame and committed-transaction counts, and the pages it changed - and the shared-memory index (-shm) - valid frame count, database size and checkpoint progress. (.sql dumps are listed under Developer / data.) Microsoft Access (MDB, ACCDB) now opens in a full table viewer - see Access database above. Concordance .dcb databases from the LexisNexis litigation review suite are identified from their bytes, and told apart from the other formats that reuse the same extension (compiled game data, speech-recognition dictionaries).

Can I open a .DB3 file online for free?

Yes. Analyser is a free online .DB3 identifier that runs entirely in your browser - your .DB3 file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What Analyser reads: Open SQLite databases (.sqlite/.db/.sqlite3) and read their full schema in-browser - every table with its columns and row counts, views, indexes, triggers, the CREATE-statement DDL, and a sample of the largest table.

Depth of analysis: .DB3 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .DB3 file: Drag a .DB3 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
