    PeerGuardian

    PeerGuardian - a privacy oriented firewall application

    PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P. PeerGuardian Linux: Not developed actively anymore. Team might still be around. Some unreleased changes on git. Outdated technology. Peerguardian OS X: Not developed anymore. We've lost contact with the OS X developer. PeerGuardian Windows: Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7. Collaboration with peerblock.com is welcome! PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).

    WiFiManager

    WiFiManager

    WiFi Connection manager with web captive portal

    Espressif ESPx WiFi Connection manager with fallback web configuration portal. The configuration portal is of the captive variety, so on various devices it will present the configuration dialogue as soon as you connect to the created access point. When your ESP starts up, it sets it up in Station mode and tries to connect to a previously saved Access Point. If this is unsuccessful (or no previous network saved) it moves the ESP into Access Point mode and spins up a DNS and WebServer (default ip 192.168.4.1). Using any wifi enabled device with a browser (computer, phone, tablet) connect to the newly created Access Point. Because of the Captive Portal and the DNS server you will either get a 'Join to network' type of popup or get any domain you try to access redirected to the configuration portal. ESP will try to connect. If successful, it relinquishes control back to your app. If not, reconnect to AP and reconfigure.
