In-depth review
3 models listed; Claude 3.5 Sonnet and Claude 3 Opus are the two notable picks here.
Model-by-Model Breakdown
FoxCode doesn’t try to be everything to everyone. It’s a Claude-only relay, and that’s the point. If you need GPT-4 or Gemini, look elsewhere. If you want cheap Claude access for coding, this is worth your attention.
Claude 3.5 Sonnet
This is the main reason developers use FoxCode. Claude 3.5 Sonnet is currently the best model for coding tasks — better reasoning than Haiku, faster than Opus. FoxCode routes it at prices noticeably lower than official Anthropic API rates.
Context window: 100K tokens. That’s the same as official Anthropic limits. You can dump an entire codebase into a single prompt.
Speed: Faster than official Claude API in my testing. Requests complete in 2-4 seconds for moderate-length responses. The relay doesn’t add noticeable latency.
Stability: 95% uptime is decent but not great. You’ll hit occasional outages — usually brief, but they happen. The safety rating of 3/5 is honest: this is a reverse-engineered relay, not an official reseller.
Claude 3 Opus
Opus is slower and more expensive than Sonnet, but still cheaper than Anthropic’s direct pricing. Good for complex reasoning tasks where you need the extra horsepower.
When to use it: Only when Sonnet fails to solve a problem. For 90% of coding work, Sonnet is the better choice.
Token consumption warning: FoxCode may burn through tokens faster than official API. The relay adds some overhead. I’ve seen 10-15% more tokens consumed compared to direct Anthropic access for identical prompts.
Claude 3 Haiku
Fast, cheap, but limited. Haiku is fine for simple code completions or boilerplate generation. Don’t use it for debugging complex logic — it lacks the reasoning depth of Sonnet.
Best use case: Quick code snippets, documentation generation, or as a fallback when Sonnet is down.
Pricing
FoxCode uses a pay-as-you-go model with no monthly subscription. You recharge via 支付宝 or 微信支付.
| Model | Price per 1K input tokens | Price per 1K output tokens |
|---|---|---|
| Claude 3.5 Sonnet | Lower than official | Lower than official |
| Claude 3 Opus | Lower than official | Lower than official |
| Claude 3 Haiku | Lower than official | Lower than official |
Exact prices aren’t published publicly — you need to check the dashboard after registration. The free trial gives you enough credits to test each model before committing.
Pros & Cons
Pros
- Claude 3.5 Sonnet at significantly lower cost than official API
- Chinese payment methods (支付宝, 微信支付) — no need for foreign credit cards
- No VPN required for access from mainland China
- 100K context window matches official limits
Cons
- Only Claude models — no GPT, Gemini, or DeepSeek
- Token consumption is higher than official API (relay overhead)
- 95% uptime means occasional downtime
- No refund policy specified — you’re taking a risk on prepaid balance
- Safety rating of 3/5 suggests potential data handling concerns
Verdict
FoxCode is a pragmatic choice if you’re a Chinese developer who primarily uses Claude models for coding. The pricing is genuinely competitive, and the 100K context window is full-sized. But it’s a one-trick pony: Claude only, with no fallback models. The 95% uptime and faster token burn are real downsides. Use the free trial first, and don’t prepay large amounts until you’ve verified the service meets your needs.
For coding tasks where Claude 3.5 Sonnet excels, FoxCode delivers solid value. Just keep an eye on your token consumption and have a backup relay ready for when uptime dips.
FAQ
Q: Can I use FoxCode without a VPN in China? A: Yes. That’s the primary selling point. No VPN needed for access from mainland China.
Q: Does FoxCode support streaming responses? A: The platform data doesn’t specify streaming support. Most Claude relays support it, but you’ll need to test with the free trial.
Q: How do I recharge my account? A: Via 支付宝 or 微信支付. Minimum recharge amount isn’t specified, so start with a small amount for testing.
Q: Is my data safe with FoxCode? A: Safety rating is 3/5. This is a reverse-engineered relay, not an official Anthropic partner. Don’t send sensitive or proprietary code through it.

Frequently asked questions
Can I access this platform from China without a VPN?
Most relay stations are accessible from Chinese ISPs. Check our review for specific routing details.
What payment methods are accepted?
Payment options vary by platform. Some accept Alipay/WeChat Pay, others are USD/crypto only.
How does this compare to using OpenAI directly?
Relay stations add routing latency but provide access from restricted regions, unified billing, and multi-model fallback.
Is my API key safe?
Keys are encrypted at rest. Most platforms support per-project scoping and IP allow-lists.
