What is Mantis?

Oct 1, 2025

We have earlier introduced Mantis, a C++ BaaS toolkit, designed to be lightweight but powerful.

Introducing Mantis: The C++ Backend Framework Built for Simplicity and Speed
In a world dominated by heavyweight frameworks and bloated deployment pipelines, Mantis stands out as a fast, modular C++ backend library designed for simplicity, speed, and embeddability. Whether you’re building for the cloud, desktop, or embedded systems, Mantis gives you modern backend capabilities with zero friction. What Makes Mantis Special?

What's changed?

From our last v0.2.7 release a couple of weeks ago, we have some important fixes and improvements added to our v0.2.8 release. Have a look:

  • PostgreSQL Support: v0.2.8 brings full PostgreSQL support for Linux builds. This allows for easy backend database switch when scaling is required while maintaining lightweight backend database (SQLite) where it's needed. How do you switch the database? Easy!
Connecting to PostgreSQL database
  • Minor bug fixes & improvements: Lots of bugs were squashed, solving some performance issues as well as mending some issues that existed. Chief among these is matching data types compatibility for SQLite to/from PostgreSQL, forcing SQLite WAL mode checkpointing for every boot and refactoring project for performance improvements.
