Understand your AI and cloud costs without jumping between provider dashboards. API Usage brings OpenAI, Anthropic, and Vercel billing data into one clear, customisable view. Connect multiple organisations, choose the metrics and time ranges that matter to you, and keep important totals visible on your Home Screen. BUILD YOUR DASHBOARD - Track daily spend across configurable time ranges - Break down costs by project, service, API key, workspace, or model - Choose list, bar, line, area, or donut chart styles - Create compact or detailed tiles for each organisation CHECK COSTS FROM YOUR HOME SCREEN - Turn any dashboard tile into a widget - Choose the organisation and metric for each widget - Use small, medium, or large widget layouts - Keep snapshots updated in the background when iOS allows MADE FOR MULTIPLE PROVIDERS - Connect more than one organisation per provider - View OpenAI, Anthropic, and Vercel independently - Add, edit, or remove organisations at any time YOUR CREDENTIALS STAY ON YOUR DEVICE Credentials are stored in the iOS Keychain. API Usage communicates directly with the provider you connect and does not send your credentials or billing data to a Barolo AI server. API Usage is an independent product and is not affiliated with, endorsed by, or sponsored by OpenAI, Anthropic, or Vercel.

SSE Inspector is a focused stream debugger for developers building with AI APIs and LLMs. It preserves the original SSE (Server-Sent Events) response and presents every packet, semantic delta, packet interval, response header, and assembled output so broken, stalled, merged, or incomplete streams are easier to diagnose. It supports OpenAI, DeepSeek, Claude, Gemini, Ollama, Llama, and custom SSE mappings. Paste a cURL command to instantly import its URL, method, headers, body, and credentials; the app automatically detects the protocol from endpoint and request characteristics. Sessions can be edited, rerun, replayed, imported, exported, and shared as redacted Debug Bundles. No account required. Sessions and credentials remain on device and are sent only to endpoints you explicitly run. Initial Release! A powerful companion for AI & LLM developers to debug Server-Sent Events. AI SSE Presets: Ready-to-use environments for OpenAI, DeepSeek, Claude, Gemini, and Ollama/Llama. Smart cURL Import: Paste cURL to automatically detect and map protocols. Deep Diagnostics: Raw SSE stream viewing, real-time response rendering, timing charts, and interval analytics. Session Management: Edit, rerun, replay, import, and export debugging sessions with ease.

Verdict
The clearest difference is iOS requirement: SSE Inspector at 17.0 against API Usage's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
