Crux compared / PubliclyBuild
Looking for a PubliclyBuild alternative?
PubliclyBuild’s domain no longer points anywhere. On the day we checked, publiclybuild.com and its www address did not resolve, so there was no page of theirs to compare against. Here is what we found, and where Crux fits.
Updated
On 18 October 2026, publiclybuild.com and www.publiclybuild.com did not resolve to any server, and a whois lookup found no registration for the domain. With no site of its own to read, we state nothing about PubliclyBuild’s features or prices. For people who want the same outcome, posts on 𝕏 from the work they push to GitHub, Crux (cruxpost.com) drafts from each batch of commits, merged pull requests and releases on the repos you pick, in your voice, and then measures how each post did against your usual one.
What we found at publiclybuild.com
On 18 October 2026 we looked up publiclybuild.com and www.publiclybuild.com. Neither name resolved, so no page loaded, and a whois query for the domain returned no match, which usually means the registration lapsed.
Directory sites may still describe the product, but our rule is to state only what a competitor’s own site says on the day we check. With the site gone, this page makes no claims about what PubliclyBuild did or cost.
For anyone who signed up, the practical effect is the same either way: no dashboard to sign in to, no drafts arriving, and email to an address at that domain has nowhere to go. Anything it held about you, such as drafts or settings, is out of reach unless the owner brings it back.
A lapsed domain usually means the product has stopped, though not always: names are sometimes moved to a new address. If PubliclyBuild turns up somewhere else under its own name, we will read that site and rewrite this page from it.
What Crux does
| Feature | Crux |
|---|---|
| Drafts posts from your GitHub work | Yes. Each push to a watched repo’s default branch, merged pull request and published release becomes three drafts in your voice, written by a free model through OpenRouter. Work is grouped until it has been quiet for 3 minutes; a release is drafted at once. |
| What it reads from your repos | Commit messages, pull request and release titles and text, the names of the files a commit changed, and repo names, through a read-only GitHub App on the repos you choose. Never a file or a diff. |
| Posts to 𝕏 for you | Only what you schedule, on Autopilot. Sign-in is read-only (tweet.read, users.read, offline.access). Drafts wait in your Inbox: Post on 𝕏 copies one and opens 𝕏 with it, for you to post. |
| Learns from how your posts do | Yes. Each post’s numbers at 1 hour, 24 hours and 7 days, against your usual post. Learnings show which kinds of post (launch, feature, fix, improvement, milestone or other), hooks, formats and topics do better or worse for you, and drafts are written with them. |
| Tests patterns against chance | Yes. A group of at least 5 posts is reported only when it falls outside 500 random draws of your own posts. |
| Coding agents and API | The Crux plugin for Claude Code and Codex sends your coding agent’s note on what changed, why and for whom, with a token you create in Settings. |
| Networks | 𝕏 only. |
| Price and trial | Pro is $19 a month or $180 a year ($15 a month), and the launch deal is Pro for life for $49 once, for the first 100 buyers. Every account starts with a 7-day free trial of Pro that needs no card. When it ends without a paid plan, the account is read-only: you can still see, download or delete your data, and choose a plan. Cancel anytime. |
We tried to read PubliclyBuild’s site on : publiclybuild.com and www.publiclybuild.com. Nothing on this page describes the product itself, because its own site could not be read.
If you relied on it
If PubliclyBuild was connected to your GitHub account, it is worth removing its access: on GitHub, open Settings, then Applications, and revoke any authorisation or installation you no longer recognise. Do the same on 𝕏 under Settings and privacy, Security and account access, Apps and sessions.
Then look at what you posted with it. Those posts are still on 𝕏, and they are useful: they show how your audience reacted when you shared your work before. Crux reads them from your archive or a read-only import and folds them into the baseline, so your first findings are not starting from zero.
Crux asks GitHub for read-only access to the repos you pick, through a GitHub App you can remove at any time, and its sign-in with 𝕏 asks only for read-only permissions. The posts you made with any earlier tool stay on your timeline, and Crux counts them in your baseline when it reads your history.
Questions to ask before trusting the next tool
A tool that writes posts from your commits sits between your code host and your public profile, so it is worth asking a few plain questions. Can it read your code, or only what you wrote about it? Can it post without you, and can you turn that off? Where does the text it reads go, and which AI provider sees it? What happens to your data if the company stops?
It also helps to know whether a tool is still looked after. A changelog with recent entries, a named person behind it and a way to reach them are cheap signals; a domain that stops resolving one day, taking its sign-in with it, is the expensive way to find out.
Finally, ask what the tool learns. Writing a post from a commit is the easy half. Knowing afterwards whether announcing fixes, sharing numbers or asking questions works better for your particular audience is the half that changes what you write next week.
For Crux the answers are on its own pages: it reads commit messages, pull request and release text and file names, never code; the privacy policy names the AI provider that writes the drafts; and you can export or delete your account and its data from Settings at any time.
