sqlite-web: A Browser-Based SQLite Database Manager in Python

What sqlite-web Solves and Who Uses It

SQLite databases are files: they ship with applications, back small Django or Flask projects, store local data for mobile apps, and appear in dozens of other contexts where a full client-server database would be overkill. Inspecting or editing these files traditionally requires a desktop GUI tool like DB Browser for SQLite, or writing SQL at the command line with the sqlite3 shell. sqlite-web takes a third path: it runs a local web server and serves a browser interface for any SQLite database file you point it at. This makes it useful on remote servers where a desktop GUI is unavailable, inside Docker containers, or in environments where installing a native application is inconvenient. The target user is a developer or analyst who already has Python and wants to browse a database immediately without additional setup. Because it runs entirely locally, no data leaves the machine unless you explicitly deploy it to a shared host.

Architecture: Flask, Peewee, and Pygments

sqlite-web depends on three Python libraries. Flask handles the web server and routing. Peewee is the ORM that sqlite-web uses internally to talk to the SQLite file: it provides the schema introspection and the CRUD operations that power the interface. Pygments provides syntax highlighting for the query results and SQL display. The application exposes one web interface for each database file passed on the command line, and a navigation bar lets you switch between tables. Multiple database files can be opened in the same session. The interface is organized into tabs per table: structure (columns, indexes, triggers, foreign keys), content (paginated data with sorting), query (free-form SQL execution), import (CSV and JSON upload), and export (CSV and JSON download). This tab structure means you can reach any operation from a single URL, with no installation of additional browser extensions or plugins.

Installing and Starting sqlite-web

The simplest installation uses pip. Run the following command to install sqlite-web and its dependencies:

pip install sqlite-web

Once installed, point it at a database file:

sqlite_web /path/to/database.db

Navigate to http://localhost:8080/ to open the interface. To open multiple databases in the same session, list them all:

sqlite_web /path/to/db1.db /path/to/db2.db /path/to/db3.db

Docker users can run sqlite-web without installing Python at all:

docker run -it --rm \
    -p 8080:8080 \
    -v /path/to/your-data:/data \
    ghcr.io/coleifer/sqlite-web:latest \
    db_filename.db

For higher throughput, the gevent WSGI entry point is available as a separate command:

sqlite_wsgi /path/to/db.db

This replaces the default Flask development server with gevent's event-driven worker pool. The pyproject.toml exposes it as a separate entry point named sqlite_wsgi.

Command-Line Options Worth Knowing

sqlite-web ships with a set of command-line flags that cover most common deployment scenarios. The port and host are configurable with -p and -H respectively, which matters when running the tool inside a container or on a machine where port 8080 is already taken. The --password flag prompts for a password at startup; the same password can be supplied through the SQLITE_WEB_PASSWORD environment variable to avoid interactive prompting. The --read-only flag opens the database in read-only mode, which prevents any accidental data modification. The --rows-per-page flag controls pagination on the content tab, defaulting to 50 rows. The --foreign-keys flag enables SQLite's foreign key constraint pragma, which is off by default in SQLite itself. Two flags control loading additional databases at runtime: --enable-load allows uploading database files through the interface, while --enable-filesystem allows specifying on-disk paths at runtime, which the README flags as something to use carefully. SSL support is available through --ssl-cert and --ssl-key flags, with an ad-hoc mode via --ad-hoc that requires the cryptography package.

Real Limitations and the Wrong Use Cases

sqlite-web inherits SQLite's single-writer constraint. SQLite handles concurrent reads well, but only one writer can hold the database lock at a time. Under the default Flask development server, multiple concurrent write requests will queue or fail. The gevent server (sqlite_wsgi) handles concurrency better for reads, but does not change the underlying SQLite locking model. The interface has no role-based access control: the --password flag covers the entire application with a single shared credential, which is unsuitable for multi-user environments where different users need different access levels. The README does not document export of the full database schema or a pg_dump-equivalent operation; only individual table data exports are available. There is also no audit log of changes made through the interface. For databases that need to stay online and serve reads from multiple processes, a client-server database like PostgreSQL is a more appropriate choice.

Maintenance, Licence, and the sqlite-web Alternative

sqlite-web is released under the MIT licence, which permits unrestricted use and redistribution. The project has no GitHub releases; the version number is maintained in the source code itself and exposed through pyproject.toml. The last push to the repository was on 2026-09-27, which indicates recent attention. The primary alternative with a similar browser-based approach is Datasette, a tool by Simon Willison that also serves SQLite databases over HTTP but focuses on read-only publishing and provides a richer plugin ecosystem. Datasette is designed for sharing data publicly; sqlite-web is designed for local editing and inspection. DB Browser for SQLite is a desktop alternative that runs natively on Windows, macOS, and Linux without a Python dependency. DB Browser is better suited to users who prefer a native GUI; sqlite-web's advantage is that it runs wherever Python runs and is accessible from any browser, including over SSH tunnels to remote machines.

Editorial conclusion

sqlite-web is the right tool for developers and data analysts who need to inspect or modify a SQLite database without installing a desktop application. It works equally well for a one-off exploration session or as a persistent local service for a team working against the same database file. It is the wrong tool for a production-facing web interface: the README does not describe multi-user access controls beyond the single password flag, and the tool is not designed for concurrent writes at high volume. Before deploying it on a shared server, verify that the --password flag or the SQLITE_WEB_PASSWORD environment variable is configured, and decide whether --read-only is appropriate for your use case.
