SuperX alternative: how SpacerrX compares
SuperX is the only tool on this list built the same way SpacerrX is, as an extension that works while you browse x.com. That makes the comparison unusually clean, because form factor is not the difference. What each one puts inside x.com is.
The short answer
SuperX is the closest tool to SpacerrX in shape: a web app plus Chrome extension that brings analytics into x.com. It also offers daily viral inspiration, posts written in your voice, an AI post and thread writer, audience-timed scheduling, Bluesky cross-posting, engagement feeds, auto-retweet, auto-plug, auto-DM and auto-delete. Plans start at $49 a month.
SpacerrX is measurement-light and action-heavy. It puts write prompts, a rotating four-quest daily board, XP and a leaderboard, AI replies and follower cleanup inside x.com. Reads and unfollows use the session already open with no authorization step. It does not automate engagement.
Side by side
| Feature | SpacerrX | SuperX |
|---|---|---|
| Form factor | Chrome extension (Manifest V3), works inside x.com | Web app plus a Chrome extension |
| Account access | Reads and unfollows run in the X session you are already logged into: no authorization step, no password. Publishing scheduled posts uses an official X connection you authorise once and can revoke | You connect your X account to their app over OAuth |
| Networks | X only | X, plus cross-posting to Bluesky |
| Non-follower tracking | Yes, free and unlimited, with follows-back and verified filters | Not offered |
| Unfollowing | One tap each, pace-warned. 20 a month free, unlimited on the Creator plan | Not offered |
| Analytics | Creator analysis: deep-dive any creator plus an AI playbook and chat. No dashboards for your own account | Deep performance breakdowns, growth and impressions over time, and key stats on any profile you visit |
| AI writing | Four questions and a wildcard every time you open the composer, your own answer sharpened into three versions, plus five replies at a time, all written from the voice profile created during onboarding | AI post writer, thread writer, and a rewrite that keeps your voice |
| Ideas and research | The Topics you save shape which questions you get asked; the niche search runs server-side inside a generation and there is no separate trending tab | High-performing niche posts surfaced daily, plus a personalised feed and custom search |
| AI replies | Five reply variations, reply characters and an optional one-off Quick instruction | SuperX Engage on Advanced and Ultra, with plan-based monthly reply limits |
| Post scheduling | Yes. Scheduled posts publish with your browser closed, plus opt-in Ghostwriter that drafts and queues on a cadence you set | Yes, with a scheduler that picks times from your audience activity |
| Engagement automation | None for engagement. Every reply, follow, and unfollow is one tap you press | Auto-retweet, auto-DM, and auto-delete |
| Priced by | A monthly AI credit pool. Follower count and account size never change the price | $49 Pro, $49 launch-priced Advanced, or $199 Ultra |

When SuperX is the better pick
- You want real analytics on your own account, which SpacerrX does not do at all.
- You want key stats on any profile you visit, without leaving your feed.
- You want automations like auto-retweet and auto-DM running for you.
- You want its higher-volume Engage feed, Signal Agents, API, CLI or MCP access.
When SpacerrX is the better pick
- You would rather not authorize a third-party app against your account just to read your own lists.
- You want live non-follower cleanup and one-tap unfollowing, which SuperX's current pages do not document.
- You want drafts in a voice you shaped on purpose, written from a profile you control.
- You would rather nothing at all acted automatically under your name.

Common questions
- Is SuperX or SpacerrX better?
- They answer different questions, despite both living in x.com. SuperX is the better tool if you want to measure account performance and profile statistics. SpacerrX is the better fit if you want write prompts that turn your own answer into posts, quests and XP for real activity, replies in your onboarding voice and free non-follower cleanup.
- Do both really run inside x.com?
- Yes. SuperX brings analytics and measurement into the page and connects the account over OAuth. SpacerrX brings Ideas, quests, replies and follower cleanup into the page, and its read-side features work through the browser session already open with no authorization step.
- Does SuperX show who doesn't follow me back?
- SuperX documents new-follower and unfollower tracking over time. Its official pages do not establish the same live non-follower cleanup workflow or one-tap unfollow action SpacerrX provides, so these are related but different features.
- Does SpacerrX have analytics like SuperX?
- No, and it is worth being blunt about it. SpacerrX has no dashboards for your own account: no impressions over time, no growth charts. What it has is creator analysis, which deep-dives any creator and hands back an AI playbook you can chat with. If you want to watch your own numbers move, SuperX is built for that and SpacerrX is not.
