Comparing LLM API providers?

Honest, no-spin comparisons. Every page says plainly when the other provider is the better pick — and when flat-rate compute (from $19/mo, no per-token billing) wins for agent workloads.

OpenRouter alternative
An LLM aggregator that fronts 400+ models from dozens of providers behind one OpenAI-compatible API, with routing and fallbacks.

Atlas Cloud alternative
A multi-modal pay-as-you-go AI aggregator — 400+ models across chat, image, video and audio behind one key, billed per token or per second of generation.

Router9 alternative
A flat-monthly LLM gateway for agent harnesses — one key across major models with per-harness budgets, audit logs and built-in multimodal skills. Flat price, but credit-metered: each plan grants a monthly credit quota.

Awan LLM alternative
A flat-rate 'unlimited tokens' inference API running open Llama-family models on its own GPUs — no token metering at all, with per-day request caps instead.

Standard Code alternative
A cloud-based autonomous coding agent by Standard Agents (standardcode.ai) — a pre-configured team of expert sub-agents that works on your codebase in resumable cloud sessions. Despite the similar name, it is a different product from Standard Compute: they sell the agent, we sell the flat-rate inference your own agent runs on.
