Side-by-side comparison
FreeLLMAPI vs OpenRouter: self-hosted free tiers or one paid hosted key?
FreeLLMAPI and OpenRouter both give you one OpenAI-compatible endpoint for many models, but they are opposites in how you pay and who runs the infrastructure. FreeLLMAPI is a free, self-hosted router over the free tiers of 34 providers. OpenRouter is a hosted service you pay per token through prepaid credits.

OpenRouterQuick answer
Start from the job you need done — the winner is the fit, not the brand.
Choose FreeLLMAPI if…
Developers who want to experiment or run personal coding agents on free provider tiers through a single endpoint, without wiring each provider's key and rate limit by hand.
Starting point: Free and open source (MIT), self-hosted; no subscription needed.
Choose OpenRouter if…
Developers and teams who want one API key for many models with hosted reliability, without running or maintaining any gateway infrastructure.
Starting point: Pay-as-you-go with prepaid credits; model prices pass through at list price.

| Main checks | Built for personal use: the project says not to expose the proxy publicly, and each provider's Terms of Service still applies. Free tiers only: no frontier models, variable latency, and no SLA; capability drops late in the day as popular models hit quotas (reset at UTC midnight). Self-hosted: you run and secure it (Docker, Docker Compose, Node 20+, or the desktop app). Free installs get monthly catalog snapshots with a delay; the live catalog is a paid Premium feature. Provider, model, and token counts are project claims that change quickly; recheck the repository before relying on them. | Hosted: requests and metadata pass through OpenRouter's infrastructure Credit top-ups carry a 5.5% platform fee Free-tier rate limits are account-wide |

The short answer
Choose FreeLLMAPI when the goal is $0 experimentation or a personal coding-agent backend and you accept variable latency, no SLA, and no frontier models on free tiers.
Choose OpenRouter when you need reliability, frontier models, or anything customer-facing: one hosted key, 400+ models from 70+ providers, pay-as-you-go credits, and no infrastructure to run.
Cost
FreeLLMAPI: $0 for the gateway (MIT, self-hosted). Optional Premium is $19/year or $49 once for the live catalog. Model usage stays inside each provider's free tier.
OpenRouter: model prices pass through at list price, with a 5.5% platform fee on credit top-ups. The free tier offers 25+ free models with 50 requests/day (limits rise with lifetime credits). BYOK is fee-free up to $25,000/month of list-price inference.
Reliability and models
FreeLLMAPI fails over between free keys, but its own documentation warns of variable latency, no SLA, and reduced capability late in the day as popular models hit quotas (reset at UTC midnight). It has no frontier models on free tiers.
OpenRouter is a managed service with automatic fallback routing across providers and access to paid frontier models. Requests and metadata pass through OpenRouter's infrastructure, which matters if you need data to stay local.
Privacy and control
FreeLLMAPI keeps provider keys local (AES-256-GCM encrypted in SQLite), but prompts still go to the free providers you configure, each with its own data terms. It says not to expose the proxy publicly.
OpenRouter centralizes keys and billing in one account, which is simpler to operate but sends traffic through a third party.
Using them together
OpenRouter is one of the providers FreeLLMAPI can pool, so a common setup is to let FreeLLMAPI absorb cheap background and experimental traffic on free tiers and reserve paid OpenRouter credits for the requests that need a frontier model or guaranteed uptime.

Match the workflow first. Check current credits, export limits, cancellation terms and commercial-use rights before purchasing.

Questions creators ask
- Is FreeLLMAPI a replacement for OpenRouter?
- For personal, low-stakes use, sometimes. For production or customer-facing apps, no: FreeLLMAPI is documented as personal-use only with no SLA and no frontier models on free tiers.
- Does OpenRouter have a free tier?
- Yes: 25+ free models from 4 providers with 50 requests/day, and limits scale with lifetime credits (under $10 vs $10 or more). Paid usage is pay-per-token with a 5.5% top-up fee.
- Which is safer for sensitive prompts?
- Neither removes third-party exposure: FreeLLMAPI sends prompts to the free providers you configure, and OpenRouter routes them through its own infrastructure. Read the data terms of every provider involved before sending confidential data.
