Giti — a high-performance, OGC geospatial engine

Giti (Persian: گیتی, "the world") is a fast, horizontally-scalable, drop-in alternative to GeoServer, built as focused microservices in Rust (CPU-heavy rendering) and Go (network-heavy services) over PostGIS, with a modern Next.js admin console.

Publish data, serve standard OGC services, style layers visually, and manage the whole thing from a clean web UI — faster and lighter than the Java stack.

Status: active development. Core OGC serving + the enterprise admin console are working. See docs/feature-parity.md for the full GeoServer parity matrix.

Features

OGC services

• WMS 1.1.1 / 1.3.0 — GetMap, GetFeatureInfo, GetCapabilities, GetLegendGraphic
  • On-the-fly reprojection — request any CRS; data reprojected via PostGIS
  • SLD styling with rule filters, scale (zoom) ranges, and labels (Vazirmatn + rustybuzz shaping → correct Persian/Arabic + RTL), halo, collision
• WFS 1.0 / 1.1 / 2.0 — GetFeature, DescribeFeatureType, output formats
• WMTS / XYZ / TMS vector tiles (MVT via ST_AsMVT) with a content-addressed cache
• WPS 1.0 processes; OGC API - Features (GeoJSON collections/items)
• GeoServer-compatible URLs, vendor params (CQL_FILTER, STYLES, …) and /rest API

Data & catalog

• Connect-anywhere store wizard: PostGIS, Shapefile, GeoPackage, GeoJSON, GeoParquet, CSV, KML/KMZ (+ MS SQL / cascade WMS-WMTS entries)
• Upload GeoJSON → ingested into PostGIS → instantly servable
• Full layer editing: title/keywords/metadata, native+declared SRS, bbox compute, feature-type details; layer groups, workspaces, stores

Styling

• Visual style builder — thematic rules (e.g. pop > 100000 → red), colors, point marks, labels (font/fill/opacity/halo), zoom ranges — no SLD by hand
• Multiple styles per layer; request one with &STYLES=<name>; SLD/CSS/YSLD/MBStyle code editor with validate

Admin console (Next.js 15, App Router)

• Modern shell: grouped nav, command palette (⌘K), drawers, toasts
• Stores / Layers / Layer Groups / Styles / Tile Cache / Security / Settings / Status
• Layer preview on an interactive map with selectable basemaps (OSM / Carto / Esri / Google) and live style switching
• English + Persian (RTL), dark / light themes

Security

• Users / groups / roles, JWT + Basic auth, GeoFence-style data rules (ALLOW / DENY / LIMIT + CQL)

Best-tool-per-job:

• Rust — wms (tiny-skia raster render, SLD, rustybuzz text shaping), tiles (MVT + cache).
• Go — gateway, catalog, auth, wfs, wps, convert.
• PostGIS — data + spatial ops pushed down to the database.
• Shared filter engine (ogc-kit Go ↔ geo-core Rust) keeps CQL→SQL byte-identical.

Quick start (Docker)

Prebuilt images are published to GitHub Container Registry by CI.

git clone https://github.com/itsmadson/giti.git
cd giti/deploy/compose
cp .env.example .env          # edit credentials
docker compose -f docker-compose.ghcr.yml up -d

Open the console at http://localhost — default admin admin / geoserver (change it in Security). Scale any service: docker compose up -d --scale wms=4.

To build from source instead:

cd deploy/compose
docker compose up -d --build

---

Container images (GHCR)

CI builds and pushes one image per service on every push to main and on tags:

ghcr.io/itsmadson/giti-gateway     ghcr.io/itsmadson/giti-catalog
ghcr.io/itsmadson/giti-auth        ghcr.io/itsmadson/giti-wms
ghcr.io/itsmadson/giti-wfs         ghcr.io/itsmadson/giti-tiles
ghcr.io/itsmadson/giti-wps         ghcr.io/itsmadson/giti-convert
ghcr.io/itsmadson/giti-frontend

Tags: latest (main) + the git SHA; semver tags on releases.
