The Privacy-First OpenRouter Alternative
OpenRouter is an aggregator that routes your requests to third-party model providers; Assisters runs its own 9 proprietary models behind an OpenAI-compatible API. That means a single owner for the model stack, a 99.9% uptime SLA, a 100K tokens/month free tier, and a guarantee that your data is never used for training. Compare pricing, models, and compatibility below.
Why developers choose an OpenRouter alternative
Developers move off pure routing layers for predictable ownership of the model stack and a privacy guarantee. Assisters runs its own 9 proprietary models, never trains on your data, and carries a 99.9% uptime SLA — versus OpenRouter, whose uptime and latency depend on the third-party provider each request is routed to.
Assisters vs OpenRouter: feature comparison
Side-by-side comparison. Assisters prices are per 1M tokens for its own models. OpenRouter is a router, so it passes through each provider's pricing and adds a 5.5% fee on credit purchases — direct per-token rows are not apples-to-apples. OpenRouter figures verified June 2026.

How is Assisters different from OpenRouter?
OpenRouter is a router that forwards your requests to third-party model providers; Assisters runs its own 9 proprietary models. Both are privacy-respecting — OpenRouter does not log prompts or completions by default — but Assisters additionally guarantees it never trains on customer data and is not a reseller.
Is Assisters open source?
Assisters runs its own proprietary models rather than open-source ones. It exposes an OpenAI-compatible API so you can integrate it with standard open tooling and the OpenAI SDKs.
How does Assisters pricing compare to OpenRouter?
The two price differently. Assisters charges per token directly — for example $0.10/M input and $0.20/M output for Chat v1, and $0.01/M for Embed v1. OpenRouter passes through each provider's pricing with no per-token markup, but adds a 5.5% fee on credit purchases ($0.80 minimum), plus a 5% fee on BYOK usage after the first 1M requests per month.
How do I migrate from OpenRouter to Assisters?
Both are OpenAI-compatible, so migration is small: set the base URL to https://api.assisters.dev/v1, replace your OpenRouter key with your Assisters API key, and use an assisters-* model name such as assisters-chat-v1 instead of an OpenRouter model slug.
