Why trust EggStriker.AI's reviews?

Independent, structured, continuously updated reviews of AI API relay providers and token relay pricing

Independent editorial ratings

We currently have no paid or commercial relationship with any provider — rankings are ordered by editorial rating. We clearly label which figures are self-reported by a vendor and which we've verified through public sources.

Direct-connect status flagged

Every provider is labeled for whether it offers a mainland-China direct-connect node, so you can avoid the hidden cost of "needs a proxy/VPN" and get a vibe-coding project up and running fast.

Price-tier comparison

Providers are split into free/budget, mid-tier, and enterprise price bands, alongside their billing model and any public referral program, so you can spot what fits your budget at a glance.

Model-switching support

Every relay in this review uses an OpenAI-compatible protocol — just change the base_url to switch between Claude/GPT/Gemini/DeepSeek with no changes to your application code.

Pitfalls to watch for

The industry has real issues with model substitution and inflated specs — our FAQs explain how to verify latency and actual model version with a small test top-up before committing.

One place for relay info

Our blog is continuously updated with provider comparisons, scenario-based relay buying guides, and current deals — the "Relay Deals" block at the top of the homepage aggregates live promotions from 60 providers to help you save money.
