The person behind EdgeQuake
Build Graph-RAG with EdgeQuake’s creator.
Raphael Mansuy designs and ships production retrieval systems in Rust. EdgeQuake is the public proof: a knowledge-graph engine on PostgreSQL with honest benchmarks, real multi-tenancy, and a demo you can open today. If you are putting Graph-RAG into production, that experience is available to you.
The portfolio is a product you can run
You do not have to take claims on faith. EdgeQuake is open source and running in public — judge the work directly.
A production Graph-RAG engine, in Rust
EdgeQuake is a single binary over PostgreSQL that turns documents into a knowledge graph and answers with sources. Not a notebook — a system built to run and upgrade.
Retrieval that fits the question
Six retrieval modes (naive, local, global, hybrid, mix, bypass) over one Postgres store, benchmarked honestly against LightRAG rather than cherry-picked.
The hard parts, handled
PDF vision and manuscript parsing, SSO and row-level multi-tenancy, MCP for agents, encrypted provider connections, and explicit, reversible migrations.
Open and in the open
Apache-2.0, 2,277 GitHub stars, shipped at v0.36.0 with a public demo and a changelog you can read.
Ways to work together
Collaboration usually starts with a short conversation about your data, your constraints, and what “good” looks like for you.
Build on EdgeQuake
Stand up Graph-RAG on your own data and infrastructure: ingestion, retrieval design, evaluation, and a deployment your team can own.
Advisory and architecture
Review your retrieval or knowledge-graph architecture, de-risk a rollout, and set a plan that holds up in production.
Partner on a product
Co-develop something new in the Graph-RAG, document-AI, or agent space where EdgeQuake is a foundation rather than the whole story.
