What Eukarya does
Eukarya Inc. is a Tokyo-based private software company founded in 2017 that builds open-source WebGIS (web-based geographic information system) tools under the Re:Earth brand, with a distributed team of about 15 people spanning Japan, Syria, the United States, Canada, China, and India. Its primary products are Re:Earth (an extensible WebGIS platform for creating and publishing 3D web-map applications without code), Re:Earth CMS (an open-source headless content-management system with versioning and API distribution, used as the data layer for the MLIT PLATEAU program), and Re:Earth Flow (a Rust-based cloud-native alternative to commercial GIS data-conversion tools such as FME). The technology stack combines a React/TypeScript front end, GraphQL APIs, WebGL/Cesium rendering, a WebAssembly-extensible plugin runtime, and a Go backend built with domain-driven design and clean architecture, while a new Rust/WebGPU-based WebGIS engine is under development for multi-platform 3D and digital-twin workloads.
The company's defining commercial anchor is its role since 2023 as the base system for the PLATEAU VIEW 3D urban-model visualization project led by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), with Re:Earth CMS deployed as PLATEAU CMS inside the same program. Revenue mechanics are a mix of contract development of research-related systems, open-source distribution (with paid SaaS for Re:Earth CMS explicitly planned but not yet launched), and conference/developer-relations-led community engagement via GitHub, FOSS4G, and corporate/engineering blogs. No product pricing, revenue, or funding figures are publicly disclosed; the firm achieved ISO/IEC 27001:2022 / JIS Q 27001:2022 certification in December 2025 from SGS Japan Inc., covering development, operation, and maintenance of its WebGIS platforms.
The company is founder-led by Kenya Tamura (CEO/Geographer) and Hiroki Inoue (CTO/Illustrator), and is structured around a hybrid go-to-market combining product-led open-source distribution globally with direct enterprise engagement inside Japan's public-sector digital-twin market through MLIT.

Eukarya product offering
Product offeringCore offering
Eukarya develops and maintains an open-source ecosystem of WebGIS software centered on Re:Earth, a no-code 3D web map platform with an extensible plugin system. The portfolio includes Re:Earth (WebGIS platform for 3D urban model visualization), Re:Earth CMS (headless CMS with schema management and API distribution), and Re:Earth Flow (cloud-native GIS data conversion tool). The products are distributed as open-source software with contract development and planned SaaS offerings serving government and developer customers.
Product overview
Eukarya offers an ecosystem centered around Re:Earth, consisting of three core open-source products: Re:Earth (WebGIS platform), Re:Earth CMS (headless CMS), and Re:Earth Flow (data conversion tool). Re:Earth serves as the foundational WebGIS platform enabling 3D map visualization and plugin extensibility; Re:Earth CMS provides flexible data management and API-based distribution; and Re:Earth Flow addresses data conversion needs. Since 2023, Re:Earth has been adopted as the base system for Japan's PLATEAU VIEW government project.

Eukarya competitors and assessment
Company assessmentBroad incumbents
- Carto: Carto is a cloud-native location intelligence and spatial analytics platform serving enterprise and government users. It competes for the same GIS customer base with broader analytics tooling than Re:Earth's visualization-first stack.
- Mapbox: Mapbox is the largest commercial web and mobile mapping platform, whose open-source fork MapLibre competes with Re:Earth. Mapbox sells proprietary SDKs and APIs that overlap with Re:Earth's WebGIS visualization capabilities.
- Esri (ArcGIS): Esri is the dominant incumbent in GIS (ArcGIS Online, ArcGIS Enterprise). Many government and enterprise customers using Re:Earth today also use Esri, making Esri the most important competitive incumbent for share of GIS budget.
Direct peers
- MapLibre GL JS: MapLibre is an open-source fork of Mapbox GL with a community governance model and SDK for web/mobile map rendering. It competes head-on with Re:Earth as a community-led, open-source mapping platform that is added into by developers worldwide.
- QGIS: QGIS is the leading open-source desktop GIS platform with a global contributor community. It competes for the same developer/analyst audience that Eukarya targets with its WebGIS stack and shares an open-source, community-driven ethos.
- Cesium (Analytical Graphics, Inc.): Cesium is the leading 3D WebGL globe and open-source 3D geospatial platform (CesiumJS), and Eukarya integrates Cesium Ion within Re:Earth. Both target developers and government/enterprise users who need 3D geospatial visualization on the web, making them the closest technological peer.
- Safe Software (FME): Safe Software is the dominant commercial GIS data-conversion and integration platform (FME), explicitly named in Eukarya's materials as the paid incumbent Re:Earth Flow aims to replace. Both serve GIS professionals needing ETL across geospatial formats.
- GeoNode: GeoNode is an open-source geospatial content management system built on Django. It is a direct open-source alternative to Re:Earth CMS for organizations publishing geospatial data via web applications.
- Boundless Geo (Galois): Boundless Geo (now part of Galois) provides open-source and enterprise GIS software around PostGIS/OpenLayers. It is a directly comparable open-source GIS vendor targeting government and enterprise geospatial customers.
Emerging players
- Strapi: Strapi is the leading open-source headless CMS, providing API-first content management with extensibility similar to Re:Earth CMS. It is comparable as a peer to Eukarya's CMS product, though focused on general content rather than GIS data.
