Prepaid multi-model wallet
Both are hosted wallets that bill models at vendor list price through one OpenAI-compatible key. OpenRouter takes 5.5% when you top up by card and lets balances go negative. RouterPlex takes $0 and stops requests at $0. OpenRouter has the bigger catalog. LLM Gateway (5% on credits, BYOK) and Vercel AI Gateway (no token markup) are the other hosted-wallet peers.

* $100 paid by card on OpenRouter yields $100 of credit for $105.50 total. OpenRouter figures from their published docs, checked 26 Aug 2026.
01 — Fees
Per-token pricing is identical on both platforms: Claude, GPT, Gemini and every other model is billed at the vendor's published list price with 0% markup. Neither platform makes money on your tokens.
The difference is what it costs to move money in. OpenRouter charges 5.5% ($0.80 minimum) on card top-ups and 5% on crypto. RouterPlex charges nothing on either. If you route $1,000 a month, that is $55 a month — $660 a year — for the same tokens. See the complete OpenRouter pricing and fee calculation.
02 — Spend safety
Both platforms support hard per-key spend budgets. The difference is the account balance itself: an OpenRouter balance can go negative mid-stream, after which requests fail with 402 errors until you repay the overdraft. A RouterPlex balance is strictly prepaid — when it hits $0, requests stop. A runaway agent or a leaked key can spend at most what you loaded, never more.
03 — Catalog
Honest trade-off: OpenRouter's catalog is far larger — hundreds of models, including community fine-tunes and niche open-source releases, plus automatic provider routing across hosts. RouterPlex carries 40 curated models across 14 providers: the frontier and value models that account for nearly all production traffic — Claude, GPT, Gemini, DeepSeek, Qwen, Kimi and more. If your workflow depends on long-tail models, OpenRouter is the right tool. See our full model list with live prices.
04 — Plans
Neither platform requires a subscription. RouterPlex additionally offers optional monthly plans whose bonus credits are worth more than the plan costs — Plex Max is $100/month for $125 in credits with $25/4-hour, $62.50/weekly, and $125/monthly spend windows. OpenRouter has no equivalent; heavy users pay the same card fee on every top-up. See plan details.
The verdict
These are different products. Choose the job you actually need, not the logo that showed up first in a search.
Switching
Both platforms are OpenAI-compatible, so there is nothing to rewrite — change the base URL and the key. Model IDs drop the provider prefix (anthropic/claude-opus-4-8 becomes claude-opus-4-8).
# before client = OpenAI(base_url="https://openrouter.ai/api/v1", api_key=OPENROUTER_KEY) # after client = OpenAI(base_url="https://api.routerplex.com/v1", api_key=ROUTERPLEX_API_KEY)

Questions
If you mostly use major-provider models (Claude, GPT, Gemini, DeepSeek, Qwen) and care about fees, yes: per-token prices are the same vendor list prices, but RouterPlex charges $0 on top-ups where OpenRouter charges 5.5% by card ($0.80 minimum) or 5% by crypto. If you need OpenRouter's much larger catalog of niche and community models, OpenRouter is the better fit.
Yes. Both bill models at the vendor's published list price with no per-token markup. The cost difference is entirely in the top-up fee: $0 on RouterPlex versus 5.5% by card or 5% by crypto on OpenRouter.
On RouterPlex, $100 — you receive $100 of token credit. On OpenRouter, $105.50 by card ($100 credit plus the 5.5% fee) or $105 by crypto.
On RouterPlex, never — requests stop when your prepaid balance reaches $0, so you can't wake up owing money. On OpenRouter, a balance can go negative and requests return 402 errors until you repay the difference.
Both expose OpenAI-compatible endpoints, so migration is a two-line change: point base_url at https://api.routerplex.com/v1 and swap in a RouterPlex API key. Model IDs are plain model names like claude-opus-4-8 — no provider prefixes.
All three are hosted wallets. OpenRouter charges 5.5% by card to fund credits. LLM Gateway charges 5% on credits and offers BYOK at 0% plus AGPLv3 self-host. Vercel publishes no platform fee on tokens (processor fees may apply) and is strongest inside the Vercel/AI SDK workflow. RouterPlex charges $0 to fund a 40-model prepaid catalog and never goes negative.
