Game with a custom networking protocol

A game built around a custom networking protocol, with the protocol design itself as the central focus. The goal is a carefully designed, necessary and sufficient protocol under which many games could be subsumed, with gameplay made fun on top of that foundation.

TracklistFinder

This web app turns YouTube DJ sets into tracklists: paste a video link and it extracts the tracks with timestamps, then creates a Spotify playlist from them with one click. It is free, requires no account, offers festival collection pages (e.g., Amsterdam Dance Event, Awakenings, DGTL), provides an API for building on it, and has a browser extension planned to show tracklists directly on the YouTube page.

Fallax

Fallax is a phishing simulation platform for companies. Instead of sending simulated phishing emails, it injects them directly into mailboxes via the Microsoft 365 or Google Workspace API, so no allowlisting in spam filters is needed and tests aren't silently blocked. Results feed into compliance platforms like Vanta and Drata as security training evidence.

Octri

Octri is an all-in-one platform for API teams: feed it an OpenAPI, Postman, or AsyncAPI spec and it generates and manages editable API docs (with an API playground, RAG-based chat, custom components, and other interactive features), idiomatic SDKs in 10 languages built with per-language experienced developers, and API + SDK monitoring that maps telemetry back to the API spec to identify slow SDK methods and API paths, track uptime and status announcements, capture errors and stack traces, and filter PII with GDPR in mind. SDK customization is handled through a visual editor with real-time code preview covering client initialization patterns, positional args vs DTOs vs kwargs, HTTP client/library, tree-shakability, and method structure/naming so generated SDKs feel hand-written. It also includes Spec Audit (planned to be open source), which scores an OpenAPI spec, explains the problems it finds, and automatically fixes a number of them.
