What is built, and what comes next
Invitations to the closed alpha go out from 1 October 2026. Follow the build from there through node graphs, open pit, drill and blast and the modules that come next.

DOCUMENTATION
From the alpha to open pit and underground
Open each phase to review its purpose and the work associated with that milestone.
The initial vision for Sarastar was formed: rebuild mining CAD around modern technology, performance, and a better user experience.
01
Market research and validation
02
Core concept development
03
Sarastar founded in 2023
The engine and the platform around it: a fast 3D renderer, the CAD core, the interface, and the accounts, licensing and update services the app needs to reach engineers.
01
Vulkan rendering engine
02
CAD engine and geometry core
03
User interface framework
04
Accounts, licensing and automatic updates
Regular updates through the alpha fill out the drafting toolset, add plotting, and move projects to a new native file format built for large mining models.
01
More CAD commands
02
Plotting and printed drawings
03
Native project format: fast to open and save, built for large models, recovers after a crash
04
Fixes and performance work from tester feedback
A node graph interface for building repeatable workflows visually: filters, legends and automations wired together once and run on every model.
01
Node graph editor for repeatable workflows
02
Graph-driven filters and legends
03
Automations that run on every model
The open pit workflow joins the alpha: drilling and geology on the terrain, block models, pit optimisation, pit design and scheduling, all from one model.
01
Drillholes, surveys and assays on the terrain
02
Lode interpretation and block models
03
Pit optimisation across revenue factors
04
Pit design: benches, berms and haul ramps to geotechnical zones
05
Mining packets and open pit scheduling
A public beta that opens Sarastar to more engineers once the alpha workflows are solid.
01
Public beta for a wider group of engineers
02
Community and training resources
03
Stability and performance
Drill and blast design for the open pit, on the same model as the pit design and the schedule.
01
Drill patterns on the pit benches
02
Charging and blast design
03
Blasts tied to the pit design and schedule
Stope and development design and underground scheduling in the same application, alongside the underground database and the open pit.
01
Stope and development design
02
Underground scheduling
03
Open pit and underground from one model
A marketplace where engineers and companies share and sell node graph workflows, scripts and templates.
01
Share and sell workflows, scripts and templates
02
Company libraries of approved workflows
