This was a massive undertaking that involved mapping the entire protocol to Python TypedDicts, which gives the user full IDE autocomplete for every command and event. I wrote about this type-safe architecture here: https://pydoll.tech/docs/deep-dive/fundamentals/typing-syste...
This design was necessary to build the advanced evasion features. To do that, I had to first understand how modern bot detection actually works, which sent me down a deep research rabbit hole. The result is a full technical encyclopedia on multi-layer fingerprinting, which I'm sharing as part of the docs: https://pydoll.tech/docs/deep-dive/fingerprinting/
The core thesis is that modern evasion isn't about randomness, it's about perfect consistency across this entire stack. Pydoll is the tool I built based on that thesis. It's open-source, and I'd love to get any and all technical feedback on the asyncio architecture, the type-safe API, or the research itself.
