About Anantastra
A free, open-source collection of web utilities engineered with privacy, speed, and clean code at its core.
"I believe software should respect people's privacy by default."
Hi! I'm Arjav Choudhary, a passionate programmer, student at Delhi Public School Jodhpur, and technology builder. What started as exploring Python as a hobby has grown into building complete web platforms, generative AI applications, and community-oriented utilities.
I created Anantastra (from Sanskrit, meaning "Infinite Instruments") because I grew tired of utility websites filled with trackers, popups, paywalls, and slow server-side page reloads. Everyday tools—like calculating loan EMIs, estimating SIP compound interest, or formatting tax figures—should be instant, accessible, and run completely within your own browser with zero data harvesting.
