Build it, publish the evidence, and grow it into usable technology.
AsopiTech is a software product R&D studio. We publish new designs as code, data, comparisons, and articles, then apply that work to customer problems in data, search, and AI through PoCs and implementation. We deliver technology you can trust down to the evidence.
Support
Please support asopi tech’s open-source development and technical writing
Your support on GitHub Sponsors keeps the OSS and technical articles coming. Help us grow open source together.
Two flagship bindings
The same high-performance DB, from Rust and Python
Alopex is Rust-native and ships official Python wheels every release. From either one, use SQL, vector search, and DataFrames with no separate infrastructure.
Value
Dive into the public R&D from what interests you
A working product, technical evidence, an article, or a book. Wherever you start, you reach real development.
EEngineering
PoCs and contract development
Turn data transformation, analytics, RAG, database, search, and data-platform questions into working implementations and evaluation results.
RR&D
Research and development
We preserve prototypes, tests, and design decisions, then grow promising work into open source and products. Watch new technology take shape up close.
EEvidence
Technical media
We write up design rationale, comparisons, experiments, and failure conditions. Dig in and use them for your own decisions.
BBooks
Books
Books for learning AI, distributed systems, and WebGPU/WASM in depth. Japanese editions are on Zenn; English editions are on Leanpub and Buy Me a Coffee. Pick up your next read.
