How the price is counted
OnlyMonster prices each OnlyFans account by its earnings over the last 30 days, from $30 a month for accounts earning up to $2,500 to $250 for accounts earning $50,000 and more. Fansly and other platforms are a flat $30 a month. Paying for 3 months saves up to 10%, 6 months up to 20%. Leeward charges a fixed price for the plan you pick, per connected model: Base $25, Pro $50, Max $150 a month, the same on OnlyFans and Fansly, with 8% off for 3 months, 18% for 6 months and 25% for a year. Both give each new model or account a 7-day free trial.
In practice, on OnlyFans the difference grows with the model’s earnings: a top-earning account costs the same in Leeward as a new one.
Where OnlyMonster is ahead
- Many more platforms. OnlyMonster lists OnlyFans, Fansly, Fanvue, Reddit, LoyalFans, Telegram, Subs, TXT.com and Tango. Leeward works with OnlyFans and Fansly only.
- A bigger team and user base. OnlyMonster says it is trusted by 2,000+ teams in 100+ countries.
- An open API and webhooks, plus the option to bring your own AI model.
Where Leeward is different
- Price doesn’t follow earnings. Base is $25 per model on OnlyFans and Fansly alike, and a yearly plan saves 25%.
- A live shift view. Who is on shift, who keeps fans waiting, PPV sent and bought per chatter, and a read-only view of any chatter’s chats as they type.
- Payroll from the timesheet. Base pay, commission and $/hour per chatter, exported to CSV.
- Telegram notifications for sales, a daily report, leak filter violations and dropped model sessions.
- An AI administrator that guides new managers and chatters through the app step by step, and the AI chatter on Max.
- Referral cashback. 5% of what agencies you bring pay, for 6 months.
Which one fits your agency
If you need Reddit, Fanvue, LoyalFans or other platforms in the same tool, OnlyMonster covers far more of them. If your models are on OnlyFans and Fansly, especially high-earning OnlyFans accounts, and you want to see the shift live and run payroll in the same app, Leeward is worth a trial. Both have a 7-day trial per account, so test them on the same models and compare.
Why agencies switch
- A fixed price per model that doesn’t climb as a model earns more.
- The owner watches the shift live, chat by chat.
- Payroll and commission come straight from the timesheet.
- Sales and dropped sessions arrive in Telegram.
