TapVoter vs OpaVote
OpaVote charges $10 for every 125 voters — or every 20 candidates — in an election, so cost rises in blocks as your ballot grows. TapVoter offers unlimited free elections with up to 10,000 voters and 30 languages.
OpaVote is well-regarded for its preference voting algorithms, particularly in academic circles. But for most organizations, TapVoter delivers the voting methods you need without the per-voter price tag.
Per-Voter Pricing Adds Up Fast
OpaVote's block pricing means a 500-voter election costs $40 — four blocks of 125 — before any candidate charge. Four of those a year is $160, and their free tier stops at 25 voters. With TapVoter every election is free for up to 10,000 voters.

Can voters cast anonymous ballots on TapVoter?
Yes. TapVoter issues each voter a unique 9-character key, so duplicate voting is prevented while an anonymous ballot mode keeps the vote itself unlinked to the voter. Every election also produces a public transparency log listing each ballot by receipt code, so a voter can confirm their own ballot was recorded and not voided.
