SuperX vs Crux
SuperX tries to cover every part of growing on ๐, from finding posts to reply to, to retweeting your own on a timer. Crux covers one loop for people who ship software: work in, drafts out, results measured.
Updated
SuperX is an all-round ๐ growth platform. Its pricing page lists a Smart Scheduler, a library of more than 10 million viral posts, an engagement feed for replies, automations (Auto Retweet, Auto Plug, Auto DM, Auto Delete), a Chrome extension, up to ten connected accounts and API, CLI and MCP access, from 49 USD a month with no free plan listed. Crux (cruxpost.com) does far less of that on purpose. It turns your pushes, merged pull requests and releases into drafts in your voice, takes notes from your coding agent, keeps a public changelog per repo, reads each post at fixed checkpoints, and reports what works for you only once a pattern beats chance. If reply volume, many accounts or automations are the job, SuperX is the stronger tool.
What SuperX is
On its own site SuperX presents one place to write, schedule and grow on ๐. The scheduler chooses when to publish; Pro covers 500 posts a month across five connected accounts, 750 AI credits, ๐ Articles publishing, Bluesky cross-posting and a web app with a Chrome extension.
The Advanced plan, at a launch price of 49 USD a month that it says is normally 99 USD, adds the AI post and thread writer, more credits, Engage with 750 replies a month and the viral library. Ultra, at 199 USD a month, raises the limits to ten accounts and 3,000 posts. Signal Agents that find leads and monthly auto-DM allowances run through all three.
What its home page and pricing page did not mention on the day we read them: any link to GitHub, a public changelog, video generation, readings at fixed times after a post, or a statistical test behind its insights.
Side by side
| Feature | Crux | SuperX |
|---|---|---|
| Drafts from GitHub commits, pull requests and releases | Yes. Each push to a watched repoโs default branch, merged pull request and published release becomes three drafts in your voice. Crux reads the text you wrote about the work and the names of changed files, never a file or a diff. | Not stated on their site |
| Coding-agent plugin | Yes. The Crux plugin for Claude Code and Codex lets your coding agent send a note on what changed, why and for whom. | No plugin is described. Pro lists full API, CLI and MCP access, and the higher plans include everything in Pro, so an agent you run can work with it. |
| Public changelog | Yes. A public changelog page for each repo you choose, with an RSS feed, on every plan. | Not stated on their site |
| Template videos | Yes. Template videos made from your work: 4 a month on Pro, 15 on Autopilot. | Not stated on their site |
| Tracking at 1 h, 24 h and 7 d | Yes. Each post from a Crux draft is read at 1 hour, 24 hours and 7 days and set against your usual post, on Pro and Autopilot. | Analytics on how each post did, when your audience is online, and how engagement turns into followers. Fixed checkpoints after a post are not described. |
| Learnings only once they beat chance | Yes. A pattern needs at least 5 posts and must fall outside 500 random draws of your own posts before it is shown. | Its home page says it analyses millions of posts. It does not say a finding about your account is tested against chance. |
| Reply feed | Yes, on Pro and Autopilot. You pick up to 3 topics and 20 accounts to watch, and each Refresh you press finds recent posts worth replying to: 3 a day on Pro, 6 on Autopilot. You post every reply yourself on ๐. | Yes. A feed that picks fresh posts to answer while they still matter; Engage, on Advanced, allows 750 replies a month. |
| Inspiration library | No. Drafts start from your own work and your own past posts, not from other peopleโs hits. | Yes. A library of more than 10 million viral posts, on Advanced. |
| Scheduling | On Autopilot: a time you pick, or a best time tested on your own posts. | Yes. A Smart Scheduler that picks the moment; Pro includes 500 posts a month. |
| Autoposting | On Autopilot, only the drafts you schedule, or Post now. No auto-retweet, auto-plug, auto-DM or auto-delete. | Yes. Scheduled posts go out on their own, and Auto Retweet, Auto Plug, Auto DM (1,000 a month on Pro) and Auto Delete run without you. |
| Free plan | No. A 7-day free trial of Pro, no card; after it, an account without a paid plan is read-only. | No free plan is listed. A free trial is offered; its length is not given. |
| Entry price | Pro: $19 a month. Autopilot, which posts for you: $29 a month. A 7-day free trial of Pro, no card. | Pro: 49 USD a month, with 5 ๐ accounts. Advanced: 49 USD a month at a launch price, normally 99 USD. Ultra: 199 USD a month, with 10 accounts. |

Where SuperX is better
- Replying at volume: Engage on Advanced allows 750 replies a month, where Cruxโs reply feed fills only when you press Refresh, 3 times a day on Pro.
- Inspiration at scale: its viral library holds more than ten million posts to borrow angles from.
- A Chrome extension, so its numbers sit next to the posts you are scrolling on ๐.
- Several accounts: five on Pro and ten on Ultra, where Crux connects one ๐ account per person.
- Automations Crux deliberately lacks: auto-retweets, plugs under posts that take off, DMs to people who engage.
- Reach beyond ๐, with cross-posting to Bluesky, and ๐ Articles publishing on Pro.
Where Crux is better
- Crux writes from the commits, merged pull requests and releases you push, so a post starts from something real you did.
- Your coding agent can tell Crux why a change matters through the plugin for Claude Code and Codex.
- Each repo can have a public changelog page with RSS, filled from the same work.
- Template videos of your work, on Pro and Autopilot.
- On Pro and Autopilot, every post from a draft is measured at fixed checkpoints, and a pattern is shown only once it beats chance.
- Every account starts with a 7-day free trial of Pro that needs no card, and Cruxโs entry plan costs less than SuperXโs cheapest, though that plan does not post for you.
Who should pick which
Pick SuperX ifโฆ
- You grow by replying to dozens of accounts every day and want an allowance sized for it.
- You manage several ๐ accounts, or a client roster, from one login.
- You want automations that retweet, plug and DM while you are away.
- You like to study viral posts before you write your own.
Pick Crux ifโฆ
- Most of what you post is what you built, and you want drafts from the work itself.
- You want to be told which kinds of post work for you only when the evidence is real.
- You want a changelog and short videos to come out of the same commits.
- You would rather not put a card on file just to try a tool.
Questions
Is Crux a SuperX replacement?
Only for part of what SuperX does. Crux has no viral library, no Chrome extension and no automations, and it connects one ๐ account; its reply feed is smaller, 3 refreshes a day on Pro and 6 on Autopilot, and you send each reply. What it adds is a source SuperX does not list: drafts written from what you push to GitHub, plus a changelog, template videos and results tested against chance.
Does SuperX have a free plan?
Its pricing page, read on 19 October 2026, lists no free plan. It offers a free trial without saying how long it lasts. The cheapest plan it lists, Pro, is 49 USD a month.
Can I use SuperX and Crux on the same ๐ account?
Yes. Crux reads your timeline and archive whatever tool posted, so posts SuperX schedules join the baseline Crux measures against. Two cautions: a post Auto Delete removes is gone before Crux can count it, and auto-retweets are reposts, which Crux leaves out.
Which one tells me what actually works on my account?
SuperX charts how each post performed and when your followers are active. Crux measures every post against the posts around it and only names a hook, format, topic or slot once its median falls outside what random groups of your own posts produce; until then it says it cannot tell.
Does either connect to my coding agent?
SuperX lists API, CLI and MCP access, so an agent you build can schedule through it. Crux ships a plugin for Claude Code and Codex whose job is narrower: after a change, your agent sends a short note on what changed and why, and Crux drafts from it.
