The Cost of English-Only Software
English-only defaults look cheap to builders, but they shift comprehension, participation, and maintenance costs onto everyone else.
English-only software can feel cheaper because the missing costs are often paid by users rather than by the team.
Users pay through extra cognitive load, reduced confidence, slower training, more support questions, and lower participation.
The cost is not only translation cost
When a project stays English-only, it often increases:
- onboarding friction
- documentation gaps
- support burden
- reviewer dependence on a few bilingual people
- exclusion from public or educational settings
Where this matters most
The cost is especially visible in civic, nonprofit, educational, and library-oriented software, where the goal is usually broader access rather than narrower filtering.
Let Books context
Let Books is intended for multilingual book-donation and preservation workflows. If the project remained effectively English-only, it would contradict its own regional and educational purpose.
Durable takeaway
English-only software is often cheaper only if the project ignores the hidden costs it has exported to users.
