Distributed as a simple binary with zero dependencies. Very easy to use and packs just the right amount of features. [See application screenshots](SCREENS.md) ## Features - Cross-platform: Mac/Linux/Windows (64bit). - Simple installation (distributed as a single binary). - Zero dependencies. - Works with PostgreSQL 9.1+. - Supports native SSH tunnels. - Multiple database sessions. - Execute and analyze custom SQL queries. - Table and query data export to CSV/JSON/XML. - Query history. - Server bookmarks. Visit [WIKI](https://github.com/sosedoff/pgweb/wiki) for more details. ## Demo Visit https://pgweb-demo.fly.dev/ to see Pgweb in action. ## Installation - [Precompiled binaries](https://github.com/sosedoff/pgweb/releases) for supported operating systems are available. - [More installation options](https://github.com/sosedoff/pgweb/wiki/Installation) ## Usage Start server: ``` pgweb ``` You can also provide connection flags: ``` pgweb --host localhost --user myuser --db mydb ``` Connection URL scheme is also supported: ``` pgweb --url postgres://user:password@host:port/database?sslmode=[mode] pgweb --url "postgres:///database?host=/absolute/path/to/unix/socket/dir" ``` ### Multiple database sessions To enable multiple database sessions in pgweb, start the server with: ``` pgweb --sessions ``` Or set environment variable: ``` PGWEB_SESSIONS=1 pgweb ``` ## Testing Before running tests, make sure you have PostgreSQL server running on `localhost:5432` interface. Also, you must have `postgres` user that could create new databases in your local environment. Pgweb server should not be running at the same time. Execute test suite: ``` make test ``` If you're using Docker locally, you might also run pgweb test suite against all supported PostgreSQL version with a single command: ``` make test-all ``` ## Contribute - Fork this repository - Create a new feature branch for a new functionality or bugfix - Commit your changes - Execute test suite - Push your code and open a new pull request - Use [issues](https://github.com/sosedoff/pgweb/issues) for any questions - Check [wiki](https://github.com/sosedoff/pgweb/wiki) for extra documentation ## License The MIT License (MIT).
