What it costs to run an app like Replika
Model prices have fallen to the point where text chat is rarely the big bill. These are published list prices as of October 26, 2026:
| Cost line | Published price | Source |
|---|---|---|
| Small chat model (OpenAI gpt-6-luna) | $0.10 per million input tokens, $0.50 per million output tokens | OpenAI pricing |
| Small chat model (Claude Haiku 5.5) | $0.10 input, $0.50 output per million tokens (prompts up to 100,000 tokens) | Anthropic pricing |
| Open model via OpenRouter (Llama 3.3 70B) | From $0.10 input, $0.32 output per million tokens, plus 5.5% on credit purchases | OpenRouter pricing |
| Image generation (FLUX schnell on Replicate) | $0.003 per image ($0.025 for flux-dev, $0.04 for flux-1.1-pro) | Replicate pricing |
| Hosting (Vercel Pro) | $20 a month, including $20 of usage credit | Vercel pricing |
| Age verification (AgeChecker.net) | $25 a month plus $0.50 per accepted check | AgeChecker.net pricing |
| Adult-friendly card processing (Verotel Basic) | 15.5% of each transaction, 10% rolling reserve for 6 months | Verotel price chart |
| Adult-friendly card processing (Epoch) | 15% for new accounts, down to 13.25% by weekly volume; $1,950 card registration | Epoch business services |
| App Store commission (Apple) | 30% standard, 15% in the Small Business Program and on subscriptions after year one | Apple Small Business Program |
As a worked example with those prices: a reply that reads 2,000 tokens of context and memory and writes 300 tokens costs about $0.00035 on a model priced at $0.10 and $0.50 per million tokens. Payment fees are bigger: on Apple's standard 30% commission, a $14.99 subscription leaves the developer about $10.49 before taxes. Replika's own price list is on the Replika pricing page.
Copying Replika's business model
Replika keeps chat free and charges for the relationship: romance mode, better memory, media and personalization. It sells through Apple and Google, which take their commission and enforce content rules, and its terms ban pornographic content. Italy's data protection authority fined its parent EUR 5 million in 2025 over missing age verification, a reminder that age checks are part of the product, not an afterthought.
An operator building for adults has a different path: sell on the web, use an adult-friendly processor (Verotel publishes 15.5%, Epoch 15% for new accounts), verify age at signup, and price chat, media and tokens for an audience the mainstream apps turn away.
How to build an app like Replika, step by step
- Pick the audience and niche before the tech: who the companion is for decides personas, content and traffic. See the niche directory.
- Choose a model and a memory design and test reply quality and cost per message.
- Build the paywall: membership tiers plus a currency for media and extras.
- Get payment approval from a processor that accepts companion apps, and add age verification.
- Produce companions and content and keep adding them.
- Drive traffic and test pricing.
