Overview

Planet Crust is a software company that builds and maintains the Corteza open-source platform, providing low-code development and support services to its customers. According to its own materials, Planet Crust is "the founder and maker of Corteza, a 100% open-source low-code platform for building advanced enterprise systems." Corteza is positioned as a fully open-source alternative for organizations that want to build advanced enterprise systems without the lock-in and cost structures of traditional proprietary platforms. Alongside Corteza, Planet Crust offers Aire, described as an AI natural-language assistant for creating Corteza applications. Aire is presented as an "AI App Builder" that lets users generate Corteza applications through natural-language interaction, lowering the barrier to building custom enterprise software. More recently, Planet Crust has promoted @Human, which it calls "The Sovereign AI Enterprise System." @Human is described as building and deploying 100% open-source AI Agents, Automations and Custom Applications without the risk, loss of control or cost of traditional enterprise platforms. The company invites prospective users to start building with @Human or to visit a demo center first. Planet Crust's offering therefore spans three connected layers: the Corteza low-code platform as the underlying enterprise application foundation, Aire as the AI-assisted application builder, and @Human as the sovereign AI enterprise system for deploying open-source AI agents, automations and custom applications. The company's public positioning emphasizes open source, customer control, and avoidance of vendor lock-in and traditional enterprise platform costs. Planet Crust operates as a private software vendor. Its public web presence is centered on planetcrust.com, where it markets Corteza, Aire and @Human and provides access to demos and free trials. The company's customers are organizations seeking low-code development and support services for building and maintaining enterprise systems.

History

Planet Crust is the company behind Corteza, a 100% open-source low-code platform for building advanced enterprise systems. Public descriptions state that Planet Crust builds and maintains the Corteza open-source platform and provides critical low-code development and support services to its customers. The company presents itself as the founder and maker of Corteza, indicating that the platform originated within or was established by Planet Crust rather than being acquired from another vendor. Corteza is positioned as a fully open-source low-code platform. This means organizations can use it to build advanced enterprise systems while retaining control over the underlying code and avoiding the lock-in associated with proprietary enterprise platforms. Planet Crust's business model combines the open-source platform with commercial development and support services for customers who need assistance building and maintaining their systems. Planet Crust later introduced Aire, an AI natural-language assistant for creating Corteza applications. Aire is marketed as an "AI App Builder," allowing users to create Corteza applications through natural-language interaction. This extends the low-code approach with AI-assisted application generation, making it easier for users to turn requirements into working applications. More recently, Planet Crust has promoted @Human, which it describes as "The Sovereign AI Enterprise System." According to the company, @Human builds and deploys 100% open-source AI Agents, Automations and Custom Applications without the risk, loss of control or cost of traditional enterprise platforms. The company offers a demo center and invites users to start building with @Human. This represents an expansion from low-code enterprise application development into sovereign, open-source AI agents and automation for the enterprise. Across these offerings, Planet Crust's history is one of building an open-source enterprise software stack: Corteza as the low-code foundation, Aire as the AI-assisted builder, and @Human as the sovereign AI enterprise system. The company remains a private software vendor whose public presence centers on planetcrust.com.
