Gortex

Code graph and intelligence engine that indexes repositories

and exposes it via CLI, MCP Server, and web UI.

---

Up to 50× fewer tokens per response. See BENCHMARK.md or reproduce it yourself.

Built for 15 AI coding agents (Claude Code, Kiro, Cursor, Windsurf, VS Code / Copilot, Continue.dev, Cline, OpenCode, Antigravity, Codex CLI, Gemini CLI, Zed, Aider, Kilo Code, OpenClaw). One install configures every one detected on your machine — see docs/agents.md.

Gortex Web UI — force-directed knowledge graph visualization

Why it matters

• 50× fewer tokens per response — graph-native lookups beat naive file reads. Agents read the symbol they need, not the 500-line file around it.
• Sub-millisecond impact analysis — a precomputed depth-3 reach index turns blast-radius queries into O(seeds × reach) map lookups. Safe to ask "what breaks if I change this?" on every edit.
• Cross-repo by default — N repos in one graph; contracts, references, and call chains span repo boundaries with evidence-gated resolution.
• Zero external dependencies — everything in-process, in-memory. No DB, no network, no model download to get started.

Install

# macOS / Linux
curl -fsSL https://get.gortex.dev | sh

# Windows (PowerShell)
irm https://get.gortex.dev/install.ps1 | iex

Detects OS/arch, verifies SHA256 + cosign, installs to PATH. Re-run to upgrade. Homebrew, .deb / .rpm / .apk, scoop, signed binaries, and from-source builds: docs/installation.md.

Quick Start

gortex install                          # one-time machine setup (MCP, skills, slash commands)
gortex daemon start --detach            # background daemon
gortex track ~/projects/myapp           # add a repo
cd ~/projects/myapp && gortex init      # per-repo: .mcp.json, hooks, community routing

Your AI assistant now uses graph queries. Full 15-minute walkthrough: docs/onboarding.md.

Highlights

• 257 languages — three tiers (bespoke tree-sitter, regex, forest-backed signatures) plus Jupyter and Databricks notebooks → docs/languages.md
• 100+ MCP tools, 16 resources, 3 prompts — symbol lookup, call chains, blast radius, dataflow, clone detection, refactoring, code actions → docs/mcp.md
• Semantic search default-on — baked GloVe-50d (3.8 MB embedded), hybrid BM25 + vector + RRF, zero deps; opt-in MiniLM / Ollama / OpenAI → docs/semantic-search.md
• Multi-repo workspaces — cross-repo symbol resolution, contract matching, impact analysis, per-session isolation → docs/multi-repo.md
• Speculative execution — preview_edit / simulate_chain answer "what would change if I applied this WorkspaceEdit?" without touching disk
• Live editor overlays — push unsaved buffers as a shadow graph; tools read through it. Branching for parallel speculative sessions
• GCX1 wire format — published, round-trippable. −27 % tokens vs JSON at same fidelity → docs/wire-format.md
• Long-living daemon — one process serves every IDE window; live fsnotify, on-disk snapshots, sub-second restart, OS-supervised lifecycle
• 9 LLM providers (optional) — local llama.cpp, Anthropic, OpenAI, Ollama, Claude / Codex CLI subprocess, Gemini, Bedrock, DeepSeek → docs/llm.md
• HTTP server + Web UI — versioned /v1/* API + MCP 2026 Streamable HTTP; standalone Next.js 15 UI with five 3D graph modes → docs/server.md
• Composable safety — verify_change, check_guards, audit_agent_config flag broken callers, guard violations, stale docs before they ship
• Agent integrations (15) — gortex init configures every detected coding assistant on the machine → docs/agents.md

Cross-Repo API Contracts

Gortex auto-detects API contracts across repos and matches providers to consumers, surfaced via the contracts MCP tool and the web UI Contracts page.

Contract type	Detection	Provider	Consumer
HTTP routes	Framework annotations (gin, Express, FastAPI, Spring, …)	Route handler	HTTP client calls (fetch, http.Get)
gRPC	Proto service definitions	Service RPC	Client stub calls
GraphQL	Schema type/field definitions	Schema	Query/mutation strings
Message topics	Kafka / RabbitMQ / NATS / Redis pub/sub	Publish calls	Subscribe calls
WebSocket	Event emit/listen patterns	emit()	on()
Env vars	os.Getenv, process.env, .env files	Setenv / .env	Getenv / process.env
OpenAPI	Swagger / OpenAPI spec files	Spec paths	(linked to HTTP routes)
Temporal workflows	Go / Java SDK annotations	Activity / workflow function	ExecuteActivity / ExecuteChildWorkflow

Contracts are normalised to canonical IDs (e.g. http::GET::/api/users/{id}) and matched across repos to detect orphan providers / consumers and mismatches. See docs/contracts.md.

Scale — battle-tested on large repos

Measured on an Apple Silicon laptop with the default CGO build.

Repository	Files	Nodes	Edges	Index time	Throughput	Peak heap
torvalds/linux	70,333	1,690,174	6,239,570	~3 min	300 files/s	5.07 GB
microsoft/vscode	10,762	204,501	808,902	~1 min	143 files/s	580 MB
zzet/gortex (self)	430	5,583	53,830	3.4s	127 files/s	52 MB

Parsing dominates wall time (65–80 %); reference resolution and search-index build scale sub-linearly.

Token savings dashboard

gortex savings reports tokens saved vs naive file reads — per-call, per-session, and cumulative across restarts, priced in USD against the headline model.

Gortex Token Savings
====================
Cost avoided:   $168.69 (claude-opus-4) across 1,878 calls · 11,246,094 tokens saved

Today       ████████░░░░░░░░   50.0%  saved 9,200 / 18,400 tokens   $0.14
Last 7 days ██████████░░░░░░   62.5%  saved 60,100 / 96,200 tokens  $0.90
All time    ███████████████░   93.3%  saved 11,246,094 / 12,050,716 tokens  $168.69

--verbose adds the per-tool breakdown; --json is machine-readable. Full reference: docs/savings.md.
