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.
