Built by Defensible Logic
Diceplots is built by Defensible Logic — a small consultancy that takes on engineering work where exact answers matter more than fast approximations.
What that means in practice
Diceplots is a worked example of the engineering posture: Rust core for correctness, exact rationals for math, deterministic caching for performance, multi-language bindings for reach, no Monte Carlo hand-waving. The consultancy takes on the same shape of problem outside the dice-math domain — probability engines, simulation, real-time systems, anything where the math has to be right and the latency has to be tight.
Where Defensible Logic shows up
- Probability and simulation engines — like the one running this site. Closed-form when possible, numerically stable when not, NIF / FFI / WASM bindings so the math is reachable from whatever your stack already uses.
- Real-time and low-latency systems — Phoenix / OTP, BEAM tuning, custom NIFs in Rust where Erlang's scheduler isn't a fit, the cache + dead-letter + observability infrastructure that makes them production-grade.
- Engineering-grade content systems — sites like diceplots.com that ship live computation alongside worked-out prose. The illustration pipeline, OG-card generator, and admin analytics on this site are all in-house.
How to start a conversation
Send a few sentences on the shape of the problem — what you're building, what the math has to be right about, and any latency / determinism / compliance constraints that already matter. We come back within a couple of business days with a sense of fit and a rough engagement model.

If you're evaluating the Diceplots engine for a product and want help wiring it in, this is the same team — consulting and engine-licensing engagements naturally pair.
