RustGIS

GeoLibre is a free, open-source, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data. It supports GeoParquet, GeoPackage, and shapefile layers, with live styling, attribute tables, saved projects, plugins, and an optional Python package for use in Jupyter notebooks. The same workspace runs in web browsers, native desktop apps, mobile apps, and Jupyter notebooks while keeping data local. Its browser-based geoprocessing tools run through WebAssembly without a server or data leaving the machine. The project is built with Tauri v2, React, TypeScript, MapLibre GL JS, DuckDB-WASM Spatial, and deck.gl, and also provides R and Python packages plus installers and mobile distribution.

GPUI Kit is an open-source Rust framework for building cross-platform desktop applications with GPUI. It provides a single dependency that re-exports the matching GPUI release, base infrastructure, styled components, and assets. Its architecture separates gpui-base for unstyled behavior, state, and infrastructure; gpui-component for the complete styled UI system; and gpui-shell for JavaScript extensions hosted by a Rust application. The project includes more than 75 documented components and primitives, data tables, virtual lists, a code editor, dock layouts, Markdown and HTML rendering, syntax highlighting, and charts. Applications can target macOS, Windows, Linux, and WebAssembly. The interaction layer includes AccessKit accessibility support, while its UI integration tests render components in headless windows and exercise pointer and keyboard input while checking state, focus, layout, and accessibility. The repository includes a component showcase and standalone examples, including dock layouts, editors, Markdown, and HTML rendering. Software source and code examples are licensed under Apache-2.0; specified documentation prose and illustrations are also offered under CC BY 4.0.

RustDesk is an open-source remote desktop application written in Rust and designed for self-hosting as an alternative to TeamViewer. It provides remote screen control, file transfer, clipboard synchronization, and TCP tunneling across major desktop and mobile platforms. Users can use the project's rendezvous and relay server, operate their own, or write a custom rendezvous/relay server; the project provides downloadable binaries and build instructions.

pgrust is an open-source reimplementation of PostgreSQL written entirely in Rust. It is wire-compatible and SQL-dialect-compatible with PostgreSQL, can use an existing PostgreSQL data directory, and is intended to show what PostgreSQL might look like with a modern Rust implementation. Its architecture includes a vectorized, push-based executor with JIT compilation, thread-based concurrency, a priority-based query scheduler, work-stealing parallel query execution, a built-in out-of-memory killer, pipelined fsync, and the pgrcolumnar column-oriented storage format. It also provides a browser-based WebAssembly build, downloadable binaries, source builds, and a Docker image compatible with the official PostgreSQL image's environment variables and data volume layout. The project reports passing PostgreSQL's regression suite, but states that it still contains bugs and is not recommended for production. Existing PostgreSQL extensions do not work because pgrust has no stable extension ABI, and its JIT compiler is tuned for Graviton4. pgrust is licensed under AGPL-3.0, while portions derived from PostgreSQL remain under the PostgreSQL License.

GeoLens is a self-hosted geospatial data catalog for collecting, indexing, previewing, and sharing GIS datasets on infrastructure controlled by one organization. It ingests uploaded and created datasets, database tables, service snapshots, and remote STAC assets, including Shapefile, GeoPackage, GeoJSON, GeoParquet, FlatGeobuf, KML/KMZ, CSV, XLSX, GeoTIFF, Cloud-Optimized GeoTIFF, and VRT raster mosaics. The catalog records dataset provenance and source state, supports pg_trgm fuzzy search and optional pgvector semantic ranking, and provides spatial analysis operations such as buffer, centroid, clip, dissolve, spatial join, and intersection. Its browser-based map builder composes and styles multi-layer maps and publishes them through links or embeddable iframes. GeoLens exposes OGC API Features and Records, STAC API 1.0, JSON-LD catalog formats, direct tile URLs, and vector tiles for use with QGIS, ArcGIS, MapLibre, and other OGC clients. The stack uses a React and MapLibre frontend, a FastAPI API, a GDAL/ogr2ogr ingestion worker, Titiler for raster tiles, PostgreSQL with PostGIS, pgvector, and pg_trgm, plus object storage and Valkey caching. The project is deployed with Docker Compose or prebuilt container images and also publishes Python, TypeScript/JavaScript, CLI, and read-only MCP packages. Optional AI features use an OpenAI-compatible endpoint or Anthropic key for natural-language dataset and map interactions. GeoLens is licensed under Apache License 2.0; its own REST API may change between minor releases, while its OGC and STAC standards surfaces are intended for client integration.
