loginllama

LoginLlama provides a real-time login-risk scoring API that returns a 0–10 risk score and explicit risk codes (e.g., IMPOSSIBLE_TRAVEL, NEW_DEVICE, KNOWN_VPN) for each login attempt. It's designed for developers and product teams to integrate into authentication flows so applications can decide to allow, require MFA, or block suspicious logins. The product emphasizes fast responses (<500ms), a fail-open design to avoid locking out users, and easy integration via SDKs or a one-prompt installer. The service is positioned for protecting production login flows from credential stuffing, account takeover, and bot traffic and includes a free tier (1,000 checks/month) to start.

LoginLlama is an AI-powered API for detecting suspicious logins and preventing fraud.

Key Features

Risk scoring (0–10)

Scores every login on a 0–10 scale for account takeover, credential stuffing, and bot traffic so apps can make real-time decisions.

Detailed risk codes

Returns explicit codes explaining why a login is suspicious (examples: IMPOSSIBLE_TRAVEL, NEW_DEVICE, KNOWN_VPN, TOR exit node).

Sub-500ms response, fail-open

Designed to respond in under 500ms and 'fails open' so the service cannot lock out legitimate users if it errors or times out.

One API call / SDKs

Simple single-endpoint API plus official SDKs and examples for Node.js, Python, PHP and frameworks like Next.js, Express, Django and Laravel.

Threat lists & device signals

Maintains lists of malicious and anonymizing IPs and uses device/browser fingerprints, geo signals, and automation detection in scoring.

MCP (read-only team queries)

Optional MCP server to query aggregated/read-only login analytics in plain language for a team (e.g., 'show me the riskiest logins this week').

Open source SDKs & public build

SDKs are open source and the project is built and shipped in public; the site highlights indie, self-funded development.

Free tier

Offers 1,000 free checks every month with no credit card required to start testing and integrating.

Use Cases

Prevent account takeover

Detect logins where a valid credential is used by an attacker (credential stuffing or purchased passwords) and block or step up to MFA.

Stop credential stuffing and bot attacks

Identify automated and scripted login traffic, headless browsers, and high-volume credential-stuffing runs to reduce fraud.

Risk-based authentication

Return a risk score and codes to drive decisions in the login path: allow, require additional verification, or block based on app thresholds.

Operational visibility

Use MCP read-only queries to surface team-level insights like average risk by browser or the riskiest logins this week.

Integrations

Node.js / Next.js / Express

Official SDK and code examples for integrating the risk check into Node-based auth flows.

Python / Django / Flask

Python SDK and examples for calling the LoginLlama API during login processing.

PHP / Laravel

PHP SDK and Laravel examples for integrating risk checks into PHP apps.

Auth0

Listed as an integration target for hooking risk checks into managed auth providers.

Supabase

Listed as an integration target for database-backed authentication flows.

Benefits

Act at the moment of login — enables blocking or stepping up authentication before a session is established.
Fast integration — one API call and official SDKs for major stacks; also provides a one-prompt installer for quick testing.
Fail-open design avoids locking out legitimate users if the service is unavailable.
Free entry-level tier (1,000 checks/month) lets teams experiment without a credit card.
Maintained threat signals (malicious & anonymizing IPs) and cross-app patterns reduce the burden of building this infrastructure in-house.

Limitations

"Fails open" by design — if LoginLlama errors or times out, the recommended behavior is to allow the login (log and let the user in).
Free tier usage is limited to 1,000 checks per month (scale requires paid plan).

Frequently Asked Questions

No verified FAQs are available.

Getting Started

  1. 1 Sign up and get an API key at https://loginllama.app/signup or https://loginllama.app/account/api.
  2. 2 Install the official SDK for your stack (examples: npm install loginllama, pip install loginllama, composer require loginllama/loginllama) or use the one-prompt installer.
  3. 3 After your authentication check succeeds, call the LoginLlama API with the user's identity_key/email, IP address and user agent.
  4. 4 Branch on the returned risk_score and risk codes in your auth flow (e.g., risk_score > 5 -> require MFA or block).
  5. 5 Log errors and always FAIL OPEN: if LoginLlama errors or times out, allow the login and log the incident as recommended.
