Slim(toolkit): Don't change anything in your container image and minify it by up to 30x (and for compiled languages even more) making it secure too! (free and open source)
What it does
SlimToolkit is a free tool that automatically shrinks software containers — the standardized packages used to ship and run applications — by up to 30 times their original size, without requiring developers to change anything about how they build their software. It also automatically adds security protections to those containers, reducing the risk of vulnerabilities without requiring specialized expertise.
Why it matters for PMs
Smaller, more secure containers mean lower cloud hosting costs, faster deployment times, and a reduced risk of security breaches — all without slowing down engineering teams or changing their existing workflows. With over 22,000 GitHub stars, this tool has strong developer adoption, signaling it addresses a real and widespread pain point in how modern software is built and shipped.
