We build software in India, so read this knowing where it comes from. The comparison is worth making honestly anyway, because a buyer who picks the wrong geography for their situation ends up unhappy with a supplier who was never going to fit, and that helps nobody. The decision turns on three things: the time zone you need to work in, the size of team you need, and how specialised the skills are.
Time zone is the most consequential and the least negotiable. Eastern Europe overlaps comfortably with Western Europe and gives a US east coast team a workable morning window. India overlaps well with Europe, the Middle East and APAC, and requires deliberate asynchronous working with the US west coast. If your engineering leadership sits in California and expects daily synchronous collaboration, that is a real argument against India, and no amount of goodwill from either side changes the arithmetic of the clock.
Scale runs the other way. India's engineering labour market is very large, which means a team of forty can be built and sustained, and replacing someone who leaves is a matter of weeks rather than a crisis. Eastern European markets are smaller and, for some specialisations, thin — excellent people, fewer of them. For a team of three to eight that is often irrelevant. For a team of thirty with turnover, it is the whole question.
On cost the ranges overlap more than the stereotype suggests, particularly at senior levels where the global market for strong engineers is fairly efficient. Anyone choosing purely on hourly rate is likely comparing different seniorities without noticing. The more useful comparison is fully loaded cost per unit of delivered work over a year, including the coordination overhead your time zone choice imposes, which rarely appears in a rate card and often dominates the difference.
Domain depth is worth checking rather than assuming. If your product touches Indian payments, Indian regulation, Indian commerce networks or the Indian market itself, the argument for an Indian team is not about cost at all — it is that the context is already in the room. Equally, some Eastern European ecosystems have unusual concentrations of specific expertise, and where that matches your problem it is a genuine reason to go there.
The honest summary is that both markets produce excellent engineers and poor ones, and the variance between firms within either geography dwarfs the variance between the geographies. Time zone and team size are structural and should decide the region. After that, judge the individual firm on how it answers difficult questions, how it describes what went wrong on its last project, and whether the people you meet in the sales process are the people who will do the work.
