Seed7 is an extensible general-purpose programming language designed by Thomas Mertes. It is syntactically similar to Pascal and Ada. Along with many other features, it provides an extension mechanism.Seed7 supports introducing new syntax elements and their semantics into the language, and allows new language constructs to be defined and written in Seed7.For example, programmers can introduce syntax and semantics of new statements and user defined operator symbols. The implementation of Seed7 differs significantly from that of languages with hard-coded syntax and semantics.

Libraries
Seed7 has many libraries, covering areas including containers, numeric functions, lexical analysis, file manipulation, networking (sockets, Transport Layer Security (TLS/SSL), Hypertext Transfer Protocol (HTTP), HTTP Secure (HTTPS), File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), etc.), graphics, pixmap and vector fonts, database independent API, Common Gateway Interface (CGI) support, data compression, archive files (tar, zip), character encoding, time and date handling, XML processing, message digests and more.These libraries reduce the need to use unportable operating system features and third-party libraries (which might not always be present) directly. Seed7 libraries contain abstraction layers for hardware, operating system and third-party libraries, e.g. graphic and database libraries. In other words, no changes are needed to move Seed7 programs between different processors or operating systems.

TLS library
Seeed7 has its own implementation of Transport Layer Security. Although the library is small if features things like AES and Elliptic-curve cryptography.

Database abstraction API
Seed7 provides a library with a database independent API.Programs can connect to MySQL, MariaDB, SQLite, PostgreSQL, Oracle, Open Database Connectivity (ODBC), Firebird, InterBase, Db2 and SQL Server databases. Independent from the database prepared statements can be created, bind variables can be used, the statements can be executed and result sets can be fetched.
