Local AI console

Talk to a model running on your own machine through Ollama or an OpenAI-compatible server — your prompts and the model's replies always go straight from your browser to your local model, never through a Reef server. Attach files for context, and pick up saved chats where you left off.

Local AI hardware benchmark

A spec-based compatibility advisor — tells you which local models your hardware can run well, which will be slow, and which to skip. Connect to Ollama below for a real, measured speed test instead of an estimate.

1. Your hardware

2. Live check against your local model server (optional)

If a local model server is running, this cross-references the table above with what you've actually got loaded — and runs a real, measured speed test instead of an estimate.

AI Database

A browsable catalog of AI models across providers — context windows, pricing, and capabilities.

    How Mauritius is attacked

    Network-level attacks (DDoS) aimed at Mauritius, by method. They try to knock servers and networks offline by sheer volume.

    • Loading…

    Cloudflare doesn't publish which ports or services these floods aimed at, or what web attacks on Mauritius tried to do.

    This counts attacks coming from Mauritius, not attacks on it: IPs in Mauritius that servers elsewhere reported for attacking them. Usually zero or one; when it rises, it's often a hacked local server or router.

    Reading the Cloudflare figures

    Percentages are shares of the attack traffic Cloudflare saw against the sites it protects, so they describe Cloudflare's customers, not every server in a country. A route's origin is where the attacking machines are, which is often a rented or hijacked server, not the attacker's home.

    Email settings

    SMTP on ports 25/465/587 is blocked outbound by some hosts (e.g. DigitalOcean droplets by default) — Resend and Brevo send over their HTTPS API instead, so they work even then. Only the selected provider is used to send; the others stay saved but idle, so you can switch back any time without losing settings.

    Get a key from resend.com/api-keys. Uses the "From address" below as the sender — it must be on a domain you've verified with Resend.

    Get an API key (not an SMTP key) from app.brevo.com/settings/keys/api. Uses the "From address" below as the sender — it must be a verified sender in your Brevo account.

    "From address" and "Site name/URL" are shared by SMTP, Resend, and Brevo — they control what recipients see, regardless of which provider is active.

    Send a test email

    Sends through whichever provider is currently active above. Save your settings first if you just changed them.
