CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.
SaaStore is a marketplace built for independent developers and small teams - a home for the software you make, not a big-tech platform.
We help you reach buyers who are actively searching for tools like yours: category placement, search visibility, and no commission on sales - you keep your own checkout.
Every listing is also hand-reviewed and carries an independent security scan, so buyers can trust what they find.
Software you can finally trust and afford.
Codechef SaaStoreThe scarce thing in software stopped being the ability to build and became the judgement to build the right thing โ and then to be found at all. SaaStore audits products before listing them, which is the only thing that makes a directory worth reading. I got a genuine security and UX report back, not just a listing form. Small catalog, high bar.
I used SaaStore to find software from independent builders, and what stood out to me was the extra layer of trust around the products. It does not feel like just another directory where anyone can list anything. The products are presented with clearer information, trust signals, and checks that make it easier to decide whether a tool is worth trying.
