What is Cotlet?
Cotlet is a hosted MCP server and REST API for apps that have no API, or one too limited to automate real work. You connect an app once and sign in yourself. Your AI agent then works in that app as you. It works with Claude, ChatGPT, Cursor, n8n and any other MCP client. Cotlet builds and maintains each integration and fixes it when the app changes. Cotlet is an independent service operated by Take Group sp. z o.o. from Katowice, Poland. Pricing: https://cotlet.dev/pricing. Integrations: https://cotlet.dev/integrations.
What is RouteMux?
RouteMux is a reliability-first AI gateway for developers and small teams who call more than one model provider. Instead of separate accounts, keys and invoices for each vendor, you get one API key and one endpoint that speaks the OpenAI, Anthropic and Google Vertex protocols. Keep the SDK you already use and change its base URL; the rest of your code stays the same. One key reaches models from OpenAI, Anthropic, Google, xAI, Meta, DeepSeek, Alibaba, Moonshot, Zhipu and MiniMax.
Requests travel over redundant upstream routes, so an incident at one provider is less likely to take your product down. Only successful requests are billed; failed requests and timeouts cost nothing. Image generation, video generation, text-to-speech and speech-to-text use the same key and balance. The console shows API keys, per-key quotas, usage and request logs in one place, and a public status page reports model availability from scheduled probes.
Pricing: Pay-as-you-go, starting at $10. A prepaid USD wallet with no subscription and no seat fees.
