Architecture deep dives explaining how 18 popular open-source tools are built. Pipeline analysis, system dynamics, and technology breakdowns — generated from source code by CodeSea.
Prefect positions itself as the anti-Airflow: no DAGs, no operators, just Python. Under the hood, though, it solves the ...
how dbt worksdbt flipped the analytics engineering model: instead of extracting data out of the warehouse to transform it, you write ...
The HuggingFace Transformers library ships thousands of model implementations in a single package. How do you architect ...
pytorch lightning architectureEvery ML researcher writes the same training loop boilerplate: data loading, gradient accumulation, checkpointing, distr...
how deepspeed worksTraining a model with a trillion parameters requires more memory than any single GPU can hold. DeepSpeed solves this wit...
An LLM call is stateless — it takes text in and returns text out. LangChain turns that primitive into applications: chai...
how llama index worksThe core problem LlamaIndex solves is simple to state: your data is in documents, but your LLM needs context windows. Th...
how vllm worksServing an LLM is a memory management problem. Each request needs a KV cache that grows with sequence length, and naive ...
how dspy worksPrompt engineering is manual tuning — you adjust words until the output looks right. DSPy treats it as an optimization p...
how autogen worksMost LLM frameworks chain calls sequentially. AutoGen takes a different approach: it creates multiple agents that talk t...
FastAPI achieves something unusual: it is one of the fastest Python web frameworks while also being one of the most deve...
nestjs architecture explainedNestJS borrows heavily from Angular: modules, decorators, dependency injection, guards. The bet is that the same pattern...
how strapi worksA headless CMS needs to solve two problems simultaneously: give content editors a visual interface, and give developers ...
Superset is what happens when you build a BI tool on top of SQLAlchemy: every data source becomes a SQL endpoint, every ...
how metabase worksMetabase solves the "everyone needs data but not everyone writes SQL" problem. Its architecture is built around a visual...
