RouterBase
RouterBase is a unified API gateway that gives developers and teams access to 200+ AI models, including GPT, Claude, Gemini, Llama, Mistral and DeepSeek, through a single OpenAI-compatible endpoint. Instead of maintaining separate keys and billing for each provider, you switch models with one line of configuration. RouterBase adds smart routing, automatic failover across providers, and unified billing, so your application keeps running even when an upstream provider has an outage. A free tier is available with no credit card required.

OpenRouter
OpenRouter is a unified interface for LLMs. OpenRouter scouts for the lowest prices and best latencies/throughputs across dozens of providers, and lets you choose how to prioritize them. No need to change your code when switching between models or providers. You can even let users choose and pay for their own. Evals are flawed; instead, compare models by how often they're used for different purposes. Chat with multiple at once in the chatroom. Model usage can be paid by users, developers, or both, and may shift in availability. You can also fetch models, prices, and limits via API. OpenRouter routes requests to the best available providers for your model, given your preferences. By default, requests are load-balanced across the top providers to maximize uptime, but you can customize how this works using the provider object in the request body. Prioritize providers that have not seen significant outages in the last 10 seconds.

Kerlig
Kerlig is an AI-powered writing assistant for Mac that helps users save time and improve their communication at work by integrating with all apps. It supports multi-language features and allows you to proofread, summarize, translate, and extract key points from PDFs, documents, and web pages.
Custom Actions and presets make it adaptable to your workflow.
Custom Actions allow for editing prompts to make the AI model perform exactly what you need. Invoke them with a single click or a keyboard shortcut.
Presets are personalized settings for AI models that give them a specific personality and guide their actions based on your preferences. For example, they can help the AI write emails in your style or take on roles like a software engineer or copywriter.
Kerlig supports over 350 AI models, including providers like OpenAI, Google Gemini, Anthropic Claude, Perplexity, AWS Bedrock, OpenRouter, and more. It also supports running local models via Ollama and LM Studio integrations.
