Question 31: Science and Technology
Consider the following :
- 1.Aarogya Setu
- 2.CoWIN
- 3.DigiLocker
- 4.DIKSHA
Which of the above are built on top of open-source digital platforms ?
AnswerUPSC’s answer is (d).
UPSC counts all four as built on open-source digital platforms: Aarogya Setu, whose code was released publicly, CoWIN, DigiLocker, which runs on open APIs under the India Stack, and DIKSHA, built on the open-source Sunbird platform. India's public digital platforms are generally designed on open standards and open-source software so that other bodies and countries can reuse them.
- 1. Aarogya Setu's source code was released for public use.
- 2. CoWIN is built on open digital public infrastructure.
- 3. DigiLocker works on open APIs of India's digital stack.
- 4. DIKSHA is built on the open-source Sunbird platform.
How you could have got this
- If you were sure statement 1 is correct, (b) goes: it leaves 1 out.
What you needed to know: Aarogya Setu's source code was released for public use.
- Then, if you were sure statement 2 is correct, (c) goes: it leaves 2 out.
What you needed to know: CoWIN is built on open digital public infrastructure.
- Then, if you were sure statement 3 is correct, (a) goes: it leaves 3 out.
What you needed to know: DigiLocker works on open APIs of India's digital stack.
Only (d) is left. You didn’t need statement 4.
Which options go is worked out from UPSC’s key and the options, not by a model.

- (a) Wrong. DigiLocker and DIKSHA are also open-source based.
- (b) Wrong. Aarogya Setu is also open-source based.
- (c) Wrong. CoWIN is also counted as open-source based.
- (d) Correct. UPSC accepts all four.
