StrataGraph

Cross-boundary code intelligence you can trust. StrataGraph builds a knowledge graph of your codebase that crosses the boundaries other tools stop at: code, API contracts (GraphQL/OpenAPI/gRPC), cloud infrastructure (SAM/CloudFormation/Terraform), the database (SQL DDL and ORM models), and the repository's own documentation. So "what breaks if I change this?" gets a complete answer: the Lambda that implements a field, the frontend that queries it, the table a handler reads, the docs that go stale, and everything in between, across every repo in your estate.

Built for reliable accuracy: every edge carries provenance and a calibrated confidence band, ambiguity is reported as ambiguity, and the linker never invents a relationship it can't defend. Accuracy reports with CI-enforced floors live in docs/accuracy/.

Quickstart

# 1. Build (Rust toolchain required)
cargo build --release            # → target/release/strata

# 2. Index your repo
strata index .                   # writes .strata/graph.duckdb

# 3. Ask questions
strata query "getPolicy"                 # find symbols/fields/resources
strata context "Query.getPolicyStats"    # 360° view: producers, consumers, callers…
strata impact "Query.getPolicyStats"     # blast radius across code, contract, and infra planes

Multi-repo estates

Declare your repos once, then query the linked whole; impact crosses repo boundaries through shared contracts:

# strata.workspace.toml
name = "my-estate"
[[repos]]
name = "backend"
path = "../backend"
[[repos]]
name = "frontend"
path = "../frontend"

strata index --workspace strata.workspace.toml
strata impact "Query.getUser" --workspace strata.workspace.toml

Wire it into your coding agent (one command)

strata init claude    # Claude Code: MCP server, steering rules, skills, scoped hooks
strata init kiro      # Kiro: MCP server, steering, lifecycle hooks

This installs a strictly-governed kit: your agent must assess blast radius before modifying anything, checks every plane the target touches (a schema field's producers and consumers, not just callers), treats confidence bands as trust policy (≥0.9 act / 0.4–0.8 verify / <0.4 say "unknown"; never present uncertain impact as certain), and flags dead contract surface. Installs are idempotent and merge-safe: existing CLAUDE.md content, MCP servers, and hooks (including a GitNexus setup) are preserved byte-for-byte. Hooks are project-scoped and silent-when-clean, with no nagging in repos that don't use StrataGraph.

Desktop app

A Tauri-based GUI for search, 360° context, impact tables, and a WebGL graph view (plane-colored nodes, confidence-weighted edges, blast-radius tinting):

cd apps/strata-desktop && npm run tauri build
open ../../target/release/bundle/macos/strata-desktop.app   # then "Open Project Folder…"

MCP server

strata mcp --db .strata/graph.duckdb              # single repo
strata mcp --workspace strata.workspace.toml      # linked estate

Tools: query, context (with producers/consumers/produces/consumes buckets), impact (contract-aware by default; include_contracts:false for code-only). The server serves the graph loaded at startup; the agent-kit hooks keep the on-disk index fresh as you edit.

Design

The full design doc (provenance/confidence bands, the plane model, accuracy methodology, roadmap) is at docs/strata-design.md.

Status

Active development. Merged: code plane for TypeScript/JavaScript (Tree-sitter + SCIP), Python, Rust, and C#; OpenAPI + GraphQL + gRPC contract planes with cross-repo estates; AWS infrastructure plane (SAM/CFN/Terraform → AppSync → contract); SQL data plane; knowledge plane (your own docs, doc comments, and spec descriptions in the graph — deterministic, with doc drift measured and docs in the blast radius); desktop GUI; agent integration (Claude Code + Kiro); and the detect-changes, rename, blast, guidance, and search-docs tools. In progress: IAM permission-gap detection. See the design doc's roadmap.

License

StrataGraph is source available under the Functional Source License v1.1, Apache 2.0 Future License (FSL-1.1-ALv2). The whole suite is here: the strata binary and all its tools, the MCP server, the desktop app, the agent kit, and multi-repo estates (--workspace). You may read, run, modify, self-host and redistribute it for any purpose other than competing with us, and two years after each release that release converts to Apache 2.0. Roadmap capabilities (org-scale hosted estates, history, collaboration, governance) will land here under the same terms.

A managed/hosted service may be offered commercially in future, for teams that would rather not self-host. The license keeps that option open while the source stays readable and free for any non-competing use. See docs/commercialisation/.
