16 years of systems that can't afford to fail - from Naval Simulators and Underwater Acoustics to the systems that run Training Institutes, Repair fleets, Temples and School transport.
Products
Not concepts. Working systems with years at sea, in classrooms and on plant floors - and where something isn't in service yet, the card says so.

Action Speed Tactical Trainer
Scenario-driven tactical training for operators, watchkeepers and command teams. Radar, ESM/EW, passive and active sonar, fire control, AIS and configurable weather - deployable on-premise, on private cloud, or fully air-gapped.

Capabilities
CAP / SIM
Physics-real maritime and multi-domain simulation: sonar and radar detection models, ship dynamics, HLA/DIS theatre-level wargames and scenario engines built from first principles.
CAP / GEO
PostGIS and TimescaleDB planning, tracking and analysis on real hydrographic and terrain data - fusing AIS, ADS-B, radar and IoT feeds. Open-source throughout and deployable on closed networks.
Read more →
CAP / CTY
Utility and asset registries, transport planning, flood modelling and command-centre dashboards - the civil application of the same geospatial core, on the city's own hardware.
Read more →
CAP / IND
PLC, HMI and SCADA control, custom embedded hardware from PCB to enclosure and industrial IoT with predictive maintenance - OT/IT-segmented, on the operator's own network.
Read more →
CAP / RF
FPGA signal processing, pressure-rated enclosures to 60 bar, custom antennas and acoustic communication straight through steel at up to 1 Mbps.
CAP / AI
Retrieval-augmented generation over your own documents, LLM integration and fine-tuning, and document intelligence - running air-gapped, with no data leaving your perimeter.
Read more →
CAP / SW
Custom ERPs and operations systems - HRMS, training, finance, field service - API-first, role-driven, AI-enabled where it earns its keep and deployable on-premise or in your own private cloud.
Geospatial
Our geospatial work runs on open-source foundations - which is precisely what lets it run on a network with no route to the internet. The charts, tints and terrain above are real output from systems we built and run.
GEO / OSS
PostGIS, GDAL, QGIS, GeoServer, MapProxy and OpenLayers - the same stack national mapping agencies run on. No per-seat licences, no vendor lock-in and source you can audit line by line. That auditability is not an ideological preference: it is the precondition for putting a system on a network nobody outside can reach.
GEO / AIR
Our GIS deployments carry their own basemaps, tiles and elevation data - GEBCO bathymetry, SRTM terrain, S-57 charts - served from inside your perimeter. Nothing calls a tile server on the public internet, because on a closed network there isn't one to call.
GEO / DAP
A shared, web-based common operating picture that fuses AIS, radar, ADS-B and sensor feeds into one plot, with combat and mission planning tools over the top. One source of truth across maritime, air, land and coastal domains.
GEO / CTY
The same geospatial core underpins urban work: utility and asset registries, transport and route planning, drainage and flood modelling and command-centre dashboards that fuse municipal feeds. We are currently in discussion on smart city work for Ahmedabad, and we build this class of system to the customer's data and the customer's network.
From the founder
“We started Varuni in 2010 with one belief: hard problems deserve engineers who won't outsource the difficult parts. 16 years later, we're building mission grade tech, institutes certify on our systems and clients from our first years are still with us.”- Chaitanya · Director & Technical Lead
In their words
“The IMS developed by Varuni Systems has delivered a transformational level of integration across the Academy. Working with Varuni Systems has been an excellent experience.”
It gives me great pleasure to commend Varuni Systems for their exemplary work in designing and implementing a Comprehensive Information Management System (IMS) for the Naval Maritime Academy (NAMAC), one of India's leading maritime training institutions under the Directorate General of Shipping.
As the Deputy Director of NAMAC during this project, I was closely involved in its planning, development and rollout. I was highly impressed with the steady progress made by the Varuni Systems team and the exceptional quality of the final system.
The IMS seamlessly consolidates all major functions - advertising, course booking, training administration, certification, record-keeping, analytics and audit support. A particularly commendable aspect has been their readiness to incorporate feedback and implement changes in response to evolving DG Shipping regulations.
The IMS has significantly strengthened NAMAC's efficiency, transparency and workflow. I wholeheartedly recommend them to any organization seeking a comprehensive, scalable and future-ready digital solution.
“They created a powerful yet incredibly simple and modular platform - in less than a year we expanded from being the sole users to establishing franchises across the country, mentoring over 5,000 students.”
When we launched Jeevan Pravaas Life Mentoring Services, our vision was to bring quality mentoring through Psychometric and Well-Being Assessments to children across the country. But every major IT firm we approached quoted extremely high prices and demanded complex technical inputs - far beyond what we, as non-technical founders, could provide.
That is when Cdr Chaitanya Chandel (Retd) from Varuni Systems stepped in and changed everything. He told us, 'You focus on your mission - leave the technology to us.' His team took complete responsibility and built our platform at a fraction of the usual cost.
Under their team leader, the Varuni Systems team delivered far more than we had imagined - a powerful yet incredibly simple and modular platform. Today, in addition to our Well-Being and Career Guidance modules, we have seamlessly integrated a Training LMS, Mid-Career Professional Mentoring and a Leadership Development Module.
The system has grown so efficiently that in less than a year, we expanded from being the sole users to establishing franchises across the country, mentoring over 5,000 students. Not once have they said, 'This can't be done.' I wholeheartedly recommend Varuni Systems to anyone looking for reliable, empathetic and mission-driven tech support.
“In the last decade, Varuni Systems has handled a wide variety of mega-scale private and government software and product development projects with professionalism and panache - the 'go-to' company for the successful fruition of one's project.”
Establishing a start-up in partnership with Varuni Systems, from conception of the idea to commercial launch of the website poles4pilots.com, was an intellectually stimulating, enriching and rewarding experience.
The whole-hearted, open-minded and proactive cooperation by the team at Varuni Systems, led by the indefatigable Chaitanya during the software development stage, ensured time-bound achievement of the objectives and KPIs. The sheer breadth and depth of knowledge and experience Chaitanya brings - across software development, deployment and marketing - inspires immense confidence.
In the last decade since our collaboration, Varuni Systems has handled a wide variety of mega-scale private and government software and product development projects with a high degree of professionalism and panache. The team has proven its mettle and stands tall amongst peer companies - the 'go to' company for successful fruition of one's project.

That's usually where we start. Write to us with the problem - not a spec - and we'll tell you honestly whether we can build it, how and what a prototype would take. You'll hear back from an engineer, not a sales team, within two working days.
