How do I open a .SQLite3-SHM file?

Drop a .SQLite3-SHM file onto Analyser at https://lab.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.

Can I open a .SQLite3-SHM file online for free?

Yes. Analyser is a free online .SQLite3-SHM identifier that runs entirely in your browser - your .SQLite3-SHM file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .SQLite3-SHM file?

A .sqlite3-shm file is the shared-memory WAL index for a .sqlite3 database, letting several processes navigate the write-ahead log at once.

Did you know: The -wal and -shm sidecars appear only while a database uses WAL journalling and vanish on a clean shutdown.
Analyser handles .SQLite3-SHM alongside related formats such as .SQLite, .SQLite3, .DB and more.
In Analyser's format library, .SQLite3-SHM sits in the Data & code category.
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. 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.
Depth of analysis: .SQLite3-SHM 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 .SQLite3-SHM file: Drag a .SQLite3-SHM 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.
