Do you need a website for your open source tool

In short
A GitHub README is enough while your users are other developers who already live on GitHub. A site starts to earn its place once you want search traffic outside GitHub or need to convince someone evaluating a tool from a name they do not recognize, usually a company deciding whether to add an unfamiliar package. It gives you a real install command and a place for benchmark numbers, but you still have to keep both accurate.
If you have shipped an open source CLI tool, package, or framework, there is a good chance the whole project lives at one GitHub URL: a README with an install line, a badge or two, and a list of options nobody reads until they need one. For most tools at most stages, that is genuinely enough.
When a README is enough
If your users are other developers finding the project through GitHub search, a package registry, or a link from someone who already uses it, they are already exactly where they need to be. A README answers "how do I install this" and "what does the API look like" as well as a site does, usually faster, since there is no second page to load. Building a site at this stage is polish spent on a problem nobody who matters yet has.
Where it breaks down
Two things change once a tool has real adoption.
Search stops routing through GitHub. Someone typing "fastest javascript bundler" or "cli for X" into Google is not searching GitHub, and a README ranks unreliably against a page built to answer that exact query. A tool that only exists on GitHub is invisible to anyone who found it by searching for the problem rather than the project.
Trust becomes the actual barrier to adoption. A developer deciding whether to npm install something from a name they do not recognize is really deciding whether to trust it, and a company evaluating the same package for production code is making that call on someone else's behalf. A README from an unfamiliar author reads the same whether the project is maintained carefully or abandoned six months ago. A page that shows the install flow working and backs a performance claim with a real comparison closes some of that gap, though stars, closed issues, and a changelog that keeps moving still matter more than any page.
What a site like Foundry actually does
Foundry is built around the two parts of a tool's homepage that are usually the weakest part of a README: the install command and the performance claim. The terminal installer switches between package managers so a visitor copies the exact line for npm, pnpm, or whatever they use, instead of translating your example themselves. The CLI configurator builds a command from the flags someone picks, so they see the command they will actually run before running it. The benchmark section renders as pure CSS, no charting library, which is most of why the whole page ships at roughly 3.2KB of JavaScript across three pages: a homepage, a quickstart, and a benchmarks page, with no build step.
What it does not do on its own
The installer and the configurator are UI. They do not know your flags or your package manager support until you write them in. The benchmark chart renders any numbers you give it just as convincingly as real ones, so the honesty burden sits entirely with whoever fills it in. A benchmark a reader cannot reproduce, or one run against a competing tool's outdated version, gets noticed and repeated by exactly the audience this page is trying to reach. If you would not defend a number in an issue thread, do not put it on the page.
Foundry also does not host your package. npm, PyPI, crates.io, or wherever your tool actually lives stays the source of truth; the site is where someone decides whether to go there.
What it costs
Foundry is free, and hosting a static site like this costs nothing on Cloudflare Pages or Netlify. Since the audience for a developer tool is not local, a .ph domain buys nothing here that a .dev, .io, or the free subdomain the host gives you does not; skip the domain until the project has enough users that a memorable URL is worth the yearly renewal.
Common questions
Does my open source project need a website, or is the GitHub README enough?
The README is enough while people find your tool through GitHub, a package registry, or a link from someone who already uses it. A site starts to matter once you want to show up for people searching the problem you solve rather than your project's name, or once a company is deciding whether to trust a package from a name it does not recognize.
Can a page like this actually make my tool look more trustworthy?
It can close part of the gap. Showing the real install command working and backing a performance claim with a comparison someone could check both help. It will not substitute for the things that actually build trust over time: issues that get answered, a changelog that keeps moving, and stars from real users.
Do I need to build my own benchmark charts, or does the template do that?
The template renders whatever numbers you give it as a chart; it does not measure anything itself. You still have to run the comparison, keep it current as versions change, and be ready to defend the methodology if someone asks.
Should I use a .ph domain for an open source tool?
Usually not. A .ph domain signals a local audience, and an open source tool's users are wherever the internet is. A generic domain, or no custom domain at all while the project is small, serves that audience better.
