- Ledger As A Service
Lacc — Headless Accounting Engine
Lacc is a multi-tenant, headless accounting engine that provides the
infrastructure needed to build modern accounting and financial management
applications. Access it through REST APIs and build your own interface.
Lacc is a multi-tenant, headless
accounting engine designed to provide the core infrastructure needed to build modern accounting and
financial management applications.
It can function as a multi-entry ledger, transaction
processing engine, and financial statement generator, while allowing you to build your own GUI, TUI,
or
completely custom interface on top of it. Instead of spending time implementing complex accounting
logic, ledger balancing, transaction handling, and financial calculations from scratch, you can focus
on
creating the experience that best fits your users and use case.
Lacc also provides
flexibility
through customizable chart-of-accounts support, allowing each tenant or implementation to structure
accounts according to its own accounting requirements. This makes it suitable for building
applications
ranging from personal finance tools and business accounting platforms to specialized financial
systems.
The engine is designed to be accessed programmatically through REST APIs, making it easy to
integrate with web applications, mobile apps, desktop software, command-line tools, or other backend
services.
The difficult part of building the accounting core is already handled. You can
focus
on building your product, interface, and workflow while Lacc takes care of the underlying accounting
infrastructure.
Simply sign up, get your API key, and start integrating.

application
Mesg — Messaging App
A multi-tenant, public-key-based end-to-end encrypted messaging platform where users are identified by
their cryptographic public keys—without requiring a mobile number, email address, or other traditional
identifiers.
Mesg handles the underlying messaging and encryption infrastructure while also
providing
headless REST APIs, allowing developers to build their own custom interfaces and integrations.

audio engine
PixAudio — Live Audio Engine
A desktop-based live audio engine with an Android control surface, designed for live performances and real-time audio processing. PixAudio works as a customizable audio plugin host, allowing performers to build and manage their own processing chains while controlling the engine remotely. It also provides a framework for creating and integrating custom audio plugins, giving developers the flexibility to extend the system for their own workflows and performances.
