Kodokod Sloth Board: the open-source teacher planner
Kodokod is an association of developers building practical tools. Its flagship project, Sloth Board, is a teacher planner designed to simplify planning, administrative schedule and invoicing for independent trainers.
What is Kodokod?
Kodokod brings together four full stack developers around a shared goal: create innovative tools and offer freelance expertise. The association does more than ship code : it structures products with real domain knowledge, especially around training industry regulations.
The team combines:
- Technical leadership and DevOps
- Full stack development
- Front-end user experience
- Trainer domain product ownership
This mix is reflected directly in Sloth Board, the teacher planner built by Kodokod for trainers and instructors.
Sloth Board: Kodokod's teacher planner
Sloth Board addresses a simple reality: trainers working across several schools scatter contracts, interventions, declarations and invoices across too many tools.
The Kodokod planner centralizes:
- Intervention planning
- Schedule linked to schools and classes
- Contract and hourly volume tracking
- Invoicing with a full business cycle
Why open source?
Kodokod chose to make Sloth Board free and open source. Trainers can install the tool locally, review the code and adapt usage to their context. A future simplified online offer is planned for those who prefer a hosted version.

Who is Sloth Board for?
Sloth Board is for teachers, trainers and independent instructors who:
- Work across multiple schools
- Want to unify planning and schedule
- Need reliable invoicing
- Prefer a transparent, self-hostable tool
How Kodokod builds the product
Development follows short iterations (2 to 4 weeks), targeting one release per month. Business foundations come first before exposing all planning and invoicing modules.
Artur, Product Owner, brings regulatory expertise and declaration obligations. Nolan leads architecture and deployment. Eren and Matheo build core features and the interface.
This organization ensures Sloth Board remains a credible teacher planner, not just a technical demo.
