NanoGPT vs OpenRouter: Which API Gateway Is Actually Better?
i ran both NanoGPT and OpenRouter side by side for 3 months. same prompts, same models, tracked every cent. here's the honest answer: NanoGPT wins on privacy, OpenRouter wins on model count. everything else is close enough that it doesn't matter as much as you think.
tl;dr: NanoGPT and OpenRouter are both API aggregators with nearly identical pricing. NanoGPT wins on privacy with zero-fee crypto deposits and email-optional accounts. OpenRouter wins on model count and faster new model availability. same models, same prices, different priorities.
Key Takeaways:
- base token rates are identical on both platforms. the $1.30 difference in a 30-day test came from processing fees, not model pricing
- NanoGPT's Monero deposits have zero processing fees vs ~3% on OpenRouter credit card deposits
- OpenRouter adds new models 1-2 days faster and has more open-source variants from providers like Together.ai
i use NanoGPT daily. i still have an OpenRouter account. i don't regret either choice, but i reach for NanoGPT 9 times out of 10.
what these platforms are
both are API aggregators. they sit between you and AI model providers (OpenAI, Anthropic, Google, etc.) and give you one API key to access everything.
NanoGPT - privacy-focused. crypto payments, email optional, minimal tracking. 400+ models.
OpenRouter - developer-focused. credit card payments, detailed analytics, model comparison tools. 300+ models.
they're not competitors in the traditional sense. they serve different priorities.
pricing: almost identical
base token rates are the same on both platforms. both pass through provider pricing with a small markup. you won't save money by switching platforms alone.
per-token rates (per 1M tokens)
short answer: GPT-4o costs $2.50/$10.00 on both platforms. Claude 3.5 Sonnet costs $3.00/$15.00 on both. identical pricing.
| model | NanoGPT input | OpenRouter input | NanoGPT output | OpenRouter output |
|---|---|---|---|---|
| GPT-4o | $2.50 | $2.50 | $10.00 | $10.00 |
| Claude 3.5 Sonnet | $3.00 | $3.00 | $15.00 | $15.00 |
| GPT-4o-mini | $0.15 | $0.15 | $0.60 | $0.60 |
| Gemini 1.5 Pro | $1.25 | $1.25 | $5.00 | $5.00 |
| Mistral Large | $2.00 | $2.00 | $6.00 | $6.00 |
same models, same prices. the difference isn't in the rates.
where the money differs: deposits
short answer: NanoGPT's Monero deposits have zero fees. OpenRouter credit card deposits cost ~3%. that's the real price difference.
| platform | payment method | processing fee | minimum deposit |
|---|---|---|---|
| NanoGPT | crypto (Monero) | $0 | $8 |
| NanoGPT | credit card | ~3% | $8 |
| OpenRouter | credit card | ~3% | $5 |
| OpenRouter | crypto | varies | $5 |
NanoGPT's zero-fee crypto deposits are the real differentiator. i've deposited with Monero probably 20 times and never paid a cent in processing fees. on OpenRouter, my credit card deposits always had the ~3% hit.
over 3 months with about $25 total spend, i saved roughly $0.75 on processing fees alone. not life-changing. but over a year at $100+ spend, it adds up. and more importantly, my crypto deposits don't show up on a credit card statement.
my 30-day cost test
short answer: NanoGPT cost $7.20 vs OpenRouter's $8.50 for the same 5M tokens. the $1.30 gap was processing fees, not base pricing.
| platform | tokens used | total cost | payment method |
|---|---|---|---|
| NanoGPT | ~5M | $7.20 | crypto (Monero) |
| OpenRouter | ~5M | $8.50 | credit card |
the $1.30 difference was almost entirely processing fees and rounding. base cost was nearly identical. don't pick your platform based on pricing alone.
models: who has more
OpenRouter claims 300+ models. NanoGPT claims 400+. both numbers are inflated by counting fine-tuned variants separately.
here's what matters: every model i actually use is on both platforms.
GPT-4o? both. Claude 3.5? both. Gemini Pro? both. Mistral Large? both. Llama 3 70B? both. GPT-4o-mini? both.
the 100-model difference is mostly quantized variants of the same model that 95% of users will never touch.
where OpenRouter wins
short answer: OpenRouter adds new models 1-2 days faster and has more open-source variants from Together.ai and Fireworks.
OpenRouter adds new models faster. when a new Claude or GPT version drops, it's usually on OpenRouter within 1-2 days. NanoGPT takes 1-3 days. not a huge gap, but if you need to test a new model the hour it releases, OpenRouter is your friend.
OpenRouter also has more open-source models from providers like Together.ai and Fireworks. if you're running specialized workloads on obscure models, OpenRouter has the edge.
where NanoGPT wins
short answer: NanoGPT's model naming is simpler with no confusing provider prefixes. you pick GPT-4o and get GPT-4o.
NanoGPT's model naming is simpler. no provider prefixes, no confusing versions. you pick "GPT-4o" and get GPT-4o. OpenRouter sometimes has multiple entries for the same model from different providers, which can be confusing.
privacy: the real difference
this is where the two platforms are genuinely different. not slightly different. fundamentally different.
OpenRouter's approach
short answer: OpenRouter requires email, tracks usage per model, logs requests, and ties payments to identity through credit cards.
- email required for signup
- usage tracked per model
- request logs for rate limiting
- credit card payments tied to identity
- US-based company, standard privacy policy
- data retention: 30 days minimum
NanoGPT's approach
short answer: NanoGPT allows crypto-only accounts with email optional, minimal tracking, Monero payments with no identity link.
- email optional - you can run crypto-only
- minimal usage tracking
- crypto payments (Monero, Bitcoin, Nano) with no identity link
- no KYC for crypto deposits
- privacy-first design philosophy
- less data retention
what this means in practice
short answer: with NanoGPT funded by Monero, your API usage is just usage, not tied to your identity. OpenRouter links everything to your email.
with OpenRouter, every API call you make is linked to your email and potentially your credit card. standard for most services.
with NanoGPT, i funded my account with Monero. no email. no name. no credit card. my API usage is just usage. not tied to me.
if you're doing anything where privacy matters - journalism, research, sensitive business queries, or you just don't want a tech company building a profile on your AI usage - this is a real architectural difference.
the downside of NanoGPT's privacy
short answer: less account recovery infrastructure. if you lose a crypto-only account, you start over. privacy trades off with convenience.
less infrastructure around account recovery. if you lose access to a crypto-only account, you're starting over. OpenRouter's email-based accounts are easier to recover. there's a trade-off between privacy and convenience.
API compatibility
both use OpenAI-compatible API format. switching between them is a one-line URL change.
| NanoGPT | OpenRouter | |
|---|---|---|
| base URL | api.nano-gpt.com/v1 | openrouter.ai/api/v1 |
| OpenAI compatible | yes | yes |
| streaming | yes | yes |
| function calling | yes | yes |
| vision support | yes | yes |
| rate limits | generous | varies by model |
what works with both: Open WebUI, LibreChat, SillyTavern, Cursor, Continue.dev, Aider, any OpenAI-compatible client.
for developers, there's no lock-in on either platform. switch between them by changing one line of config.
user experience
NanoGPT's UI
short answer: NanoGPT's UI is clean and minimal. no clutter. it lets you pick a model and send a prompt. that's it.
clean and minimal. no clutter, no ads. the model selector does its job. it's not winning design awards, but i don't need it to. i need it to let me pick a model and send a prompt. it does that.
mobile works in a browser, no native app.
OpenRouter's UI
short answer: OpenRouter's UI has model comparison tools, usage analytics, and a playground for testing models side by side.
more feature-rich. model comparison tools, usage analytics dashboard, a playground for testing models. feels more like a developer tool.
if you want to benchmark models against each other or analyze your token usage across providers, OpenRouter has better tooling.
my take
short answer: for daily use, NanoGPT's simplicity wins. OpenRouter is better for benchmarking and exploring new models.
NanoGPT's UI is better for daily use. OpenRouter's UI is better for exploration and analysis. i spend 95% of my time just sending prompts, so NanoGPT's simplicity wins.
reliability
both have been solid. neither has had a major outage that affected me in 3 months.
| NanoGPT | OpenRouter | |
|---|---|---|
| uptime (my test) | ~99.5% | ~99.5% |
| average latency | fast | fast |
| peak hour slowdowns | rare | occasional |
OpenRouter has been around since 2023 - more battle-tested infrastructure. NanoGPT launched in 2024 but has been reliable for me.
who should use which
NanoGPT if you:
short answer: choose NanoGPT if you value privacy, pay with crypto, want zero deposit fees, and prefer simple interfaces.
- value privacy and want anonymous usage
- pay with crypto (especially Monero)
- want zero processing fees on deposits
- prefer simple interfaces
- use a small number of core models
OpenRouter if you:
short answer: choose OpenRouter if you need every model the day it drops, want analytics tools, or prefer credit card payments.
- need every open-source model the day it drops
- want detailed usage analytics and model comparison tools
- prefer credit card payments
- are building production apps that need model diversity
- want a playground to test models side by side
both if you:
short answer: use both if you're a developer wanting redundancy, maximum model selection, and privacy for some use cases.
- are a developer who wants redundancy
- want the widest possible model selection
- care about privacy for some use cases and model variety for others
that's what i do. NanoGPT is my daily driver. OpenRouter is my backup for the occasional niche model.
the verdict
after 3 months, NanoGPT is my primary. the privacy angle matters to me - i don't want my AI usage on a credit card statement. the pricing is effectively the same. and every model i actually use daily is on both platforms.
OpenRouter is the better choice if you're a developer who needs maximum model diversity and detailed analytics. for everyone else - especially if you care about privacy - NanoGPT is the better pick.
