Why startups use Anvat
Try every model from one integration
Claude Opus 4.8, Sonnet 4.6, Haiku 4.5, GPT-5.5, GPT-5 Mini, Gemini 3.5 Flash, DeepSeek V4 Pro — all under one API key. Swap models with one param, no second account setup.
Sane defaults that grow with you
Free tier with $2 signup credit, hard caps to prevent runaway bills, Pro / Pro X5 / Ultra subscriptions with monthly credit grant that's cheaper than the equivalent Anthropic plan.
Honest billing, auditable logs
Per-request cost header on every response. Real-time usage dashboard. No hidden markup, no rounding, no per-seat fees. We tell you what each request cost.
Where the math actually changes
| What hurts today | What changes on Anvat |
|---|---|
| Burning runway on full-list Anthropic and OpenAI bills | 30% off every token, 2× credit match — effective spend ~50% lower |
| Locked into one provider after MVP — switching is painful | One integration, every frontier model. Swap with one param. |
| Unexpected $4,000 month when a feature went viral | Hard spend caps + rate limits per key. No surprise bills. |
| Procurement saying 'wait, the spend just doubled — explain' | Per-request cost header + auditable dashboard. Procurement gets a CSV, not a surprise. |
| Free tier ends just when you're ready to validate | $2 free signup credit + pay-as-you-go from $0.20 keeps you experimenting for free. |
Recommended plan
Pay-as-you-go (Free) → Pro at $20/mo
Start free with $2 credit while you validate. Move to Pro ($150 credit/month + higher RPM) when AI features are real traffic. Upgrade to Pro X5 when you're past $400/mo gateway spend — pricing crosses over there.
See plan details →Questions startups ask before signing up
→We're 4 founders shipping an MVP. Why not just use Anthropic direct?
You can. We're the same model behind the same SDK — switching back is free. The trade you're making is: 30% off + 2× credit match + one key for every provider + per-request cost header + spend caps you can set per key. If runway matters, that math compounds fast.
→What happens if a feature goes viral and we hit our credit?
We hard-block at the spend cap you set — better a 402 than a $10,000 surprise. Top up with one click at /app/billing; the gateway resumes within seconds. You can also set per-key rate limits so a single buggy worker can't drain the whole account.
→Can we get an invoice for accounting / startup program credits?
Yes. Stripe issues a real invoice for every prepaid pack and every subscription cycle. Itemised by request type — we don't hide what we charged for.
→Is there a lock-in period?
No. The SDK is unchanged — point ANTHROPIC_BASE_URL back at api.anthropic.com and you're off Anvat. We've made the off-ramp deliberately frictionless because we earn our keep on the unit economics, not the contract.
→Do you have a startup program / equity-for-credit?
Not a formal program — but if you're YC / Antler / Techstars / etc. and want bulk credit at a discount, email hello@anvat.app and we'll work something out. We'd rather grow with you than charge you full freight today.
