Native Zig Datalog engine for taint analysis and access control, but niche use cases limit reach.

Strengths
  • •Pure Zig implementation means zero external dependencies and tight control over the runtime
  • •Datalog's recursive queries solve expressiveness gaps SQL has—legitimately better for taint/reachability problems
  • •Early-stage but ships with tests, docs, and real use-case examples (security, data lineage)
Weaknesses
  • •Datalog itself is niche—most developers reach for SQL, graph DBs, or constraint solvers instead
  • •No performance benchmarks against existing Datalog engines (Soufflé, DDlog); unclear if speed or size is actually competitive
Target Audience

Systems engineers, language designers, security researchers needing logic programming without SQL overhead

Post Description

Hi everyone,

I've made an early version of a Datalog engine (called Zodd) in Zig. Datalog is a logic query language. It's not as well-known as SQL, but it has its own use cases. If you're interested to know more about the project, including its possible use cases and features, you can check projec's GitHub repo: https://github.com/CogitatorTech/zodd
