Kolatron Engineering
BASED IN THE UK

Kolatron Engineering is a platform of tools built specifically for engineers. Not adapted from generic software, designed from the ground up for the people who deal with real machines, real faults and real downtime pressure every day.

The idea is simple: useful engineering tools should be free and accessible to everyone. Calculators, analysis tools and reference utilities are available without any account or signup. For teams that need more, full maintenance management, private workspaces and collaborative tools, that is available too.

The platform is growing. New tools are added regularly based on what engineers actually need. If there is a tool that would make your job easier, request it.
