RTK (Rust Token Killer) is an open‑source command‑line proxy written in Rust. It intercepts common development commands—git, grep, cargo, pytest, docker, kubectl, and hundreds of others—removing boilerplate noise while preserving errors and test failures, dramatically reducing the token count sent to large language models. Designed for developers who rely on AI coding assistants, RTK runs as a single binary on Windows, macOS, and Linux, requires no API keys, telemetry, or external dependencies, and can be self‑hosted with zero cost.
Docker is an open platform for developing, shipping, and running applications using containerization technology.
Free for personal use and small businesses; paid plans start at $9/user/month.

4.3 (3)Works, with some caveats
Mixed feelings about Docker after using it for a while. On the plus side, industry-standard containerization technology. That said, learning curve for networking and volumes, which held us back from rating it higher.
Highly recommend Docker
Been a daily user of Docker for a while now. Huge ecosystem and community. No major complaints so far. Would recommend to anyone considering it.
Great tool for development
We've been using Docker for a few months now and it's genuinely made a difference for our team. Huge ecosystem and community. No major complaints so far. Would recommend to anyone considering it.
