NearSight vs Kodura SSL Analyzer

See the hidden world around you. NearSight listens for the Bluetooth Low Energy (BLE) signals that nearby devices are constantly broadcasting and decodes what they actually are. Earbuds, watches, fitness trackers, beacons, smart-home sensors, item trackers, and more turn from anonymous radio noise into a clear, readable list right on your iPhone. WHAT YOU CAN DO • Scan live. Watch nearby devices appear in real time, sorted by how close they are. • Know what's there. NearSight recognizes a growing catalog of device types and shows make, model, and what each signal means, not just a cryptic address. • Notice the unexpected. Surface unknown or unfamiliar devices around you and decide for yourself what belongs. • Go deeper. Open any device to inspect its raw advertisement, signal strength, and parsed technical details. OPTIONAL AI INSIGHTS Turn on AI to get plain-language explanations of what NearSight is seeing. Bring your own Anthropic or OpenAI API key, or run a compact model entirely on your device. Your choice. AI is completely optional and stays off until you enable it. PRIVATE BY DESIGN Scanning happens on your iPhone. NearSight works fully offline and shows what it sees to no one but you. AI insights and anonymous telemetry are strictly opt-in and off by default. Nothing leaves your device unless you turn it on. No ads, no third-party tracking, no account required. WHAT NEARSIGHT CAN (AND CAN'T) SEE NearSight decodes the Bluetooth signals that devices broadcast but it can't see everything: • Not every device is recognized. New or niche hardware may show up as Unknown until we've researched it and added support. • Some devices are intentionally excluded. We don't surface certain safety-sensitive devices (for example personal panic buttons), because revealing someone's private safety equipment could put them at risk. However, AI Insights may identify such devices. • It only sees Bluetooth. Devices that are powered off, not currently broadcasting, or that use other radios (Wi-Fi-only cameras, wired, or cellular devices) are invisible to NearSight. NearSight is a Bluetooth explorer, not a safety or security device, bug sweeper, or hidden-camera detector. It cannot guarantee it will find every tracker, camera, or listening device near you, and not seeing something here does not mean it isn't there. If you have a real safety concern, use dedicated tools and contact local authorities. Questions, or a device you'd like us to identify? Email hello@nearsight.one.

A TLS checker that tells you what is wrong, not just what is there. Point it at any host and port. It performs a real TLS handshake, reads the certificate chain the server actually sent, and turns it into plain language: what the problem is, why it matters, and what to change. SEES WHAT YOUR BROWSER HIDES Browsers and most phone tools quietly download any certificate a server forgot to include, so a misconfigured server looks perfectly healthy. This turns that repair off. If your server is missing an intermediate, you will see it here and nowhere else — which is why a site can work in Safari while your API client, your mobile SDK, or anything behind a strict firewall fails against it. ANSWERS IN THREE LAYERS A letter grade and one sentence you can read in a second. Then a finding for each problem — what was detected, the practical consequence, and the fix. Then every field of every certificate, for when you want to check the working yourself. WHAT IT CHECKS • Trust chain — complete, incomplete, or untrusted, and exactly where it breaks • Expiration — how long you have, and when to start worrying • Hostname — whether the certificate really covers the name you connected to • Certificate — signature algorithm, key size, validity dates • Protocols — which TLS versions are enabled, including ones that should not be • Cipher — forward secrecy and whether the negotiated suite is still sound THE CHAIN, DRAWN Every certificate the server presented, in order, leaf to root. Where a certificate is missing, the gap is drawn and labelled rather than quietly skipped. Tap any certificate for its full detail: subject, issuer, serial, both fingerprints, key, and every name it covers. BUILT FOR THE AWKWARD CASES Any port, not just 443. Self-signed certificates identified as such rather than dismissed. Deprecated TLS 1.0 and 1.1 reported against RFC 8996. Protocol probes that say "no answer" instead of claiming a version is disabled when the network simply swallowed the handshake. SHARE THE ANSWER Every scan exports as plain text — grade, chain, findings, impact and fix. Paste it into a ticket or send it to whoever owns the server. HISTORY Every endpoint you scan is kept, with its grade, so you can come back and see what you found. Rescan any of them in one tap. LIGHT AND DARK Both designed, not one inverted into the other. Fingerprints, serials and addresses are set in monospace so they stay readable at a glance and selectable when you need to paste one. NO ACCOUNT, NO BACKEND, NO ADS Scans run directly from your device to the host you type. Nothing is sent to Kodura. History never leaves the phone. There is no sign-up, no tracking prompt, and nothing to buy. Built by Kodura for network engineers, sysadmins and anyone who has lost an afternoon to a certificate that worked in a browser.
