The Hidden Costs Nobody Talks About#

When comparing prices, look beyond the headline number:

Per-Seat Pricing#

Some platforms charge per user:

• Mintlify: $20/month per editor after first 5
• Notion: $10/month per user
• GitBook: Included in tiers (but tiers have limits)
• Dokly: Included (no per-seat fees on Pro)

A 10-person team on Mintlify pays $400/month, not $300.

Usage Overages#

Watch for metered features:

• Mintlify AI: $0.15 per message after 250/month
• Some API docs tools: Per-request pricing

Annual Lock-In#

Many platforms offer "discounts" for annual billing. That's really a lock-in. If the product doesn't work out, you've prepaid for 12 months.

Dokly tip: We offer monthly billing with no penalty. Try it, cancel anytime.

The Real Cost Comparison#

Here's what a year actually costs for a small team (2-3 editors):

The winner for most teams: Dokly Pro at $588/year vs. Mintlify at $3,600/year.
