About

Dropbear is a relatively small SSH server and client. It runs on a variety of Unix platforms. Dropbear is open-source software, distributed under an MIT-style license. Dropbear is particularly useful for "embedded"-type Linux (or other Unix) systems, such as wireless routers. If you want to be notified of new releases, or for general discussion of Dropbear, you can subscribe to the relatively low-volume mailing list. With a small memory footprint suitable for memory-constrained environments, Dropbear can compile to a 110kB statically linked binary with uClibc on x86 (only minimal options selected) Dropbear server implements X11 forwarding and authentication-agent forwarding for OpenSSH clients. The server, client, keygen, and key converter can be compiled into a single binary (like busybox) Features can easily be disabled when compiling to save space. The multi-hop mode uses SSH TCP forwarding to tunnel through multiple SSH hosts in a single command.

About

NullClaw is an ultra-lightweight autonomous AI assistant infrastructure built in Zig and distributed as a single static binary designed to run efficiently on virtually any hardware. It emphasizes extreme performance and minimal resource usage, shipping as a roughly 678 KB executable that typically consumes about 1 MB of RAM and boots in under two milliseconds. It eliminates traditional runtime overhead by avoiding virtual machines, interpreters, and complex dependency chains, allowing developers to deploy agents simply by running the compiled binary. Despite its small footprint, the framework provides a full autonomous agent stack with support for more than 22 model providers, 18 communication channels, hybrid vector and FTS5 memory, streaming, voice, and multi-layer sandboxing. Security is built in through workspace scoping, explicit command allowlists, encrypted secrets, and strict sandbox isolation using tools such as Landlock, Firejail, or Docker.
