Best Free Manus Alternatives, Tested (2026)
Manus made the general-purpose agent famous — and put it behind an account and a paywall. Type a task on its homepage and Manus politely saves your message until you log in; its pricing page starts at $20 a month. So we took the five alternatives every "free Manus alternatives" list recommends and gave each one the same real task, creating zero accounts. Not one of them would run it. This page is the evidence.
The comparison table
| Tool | Free plan | Runs a task with no account? | Where the wall is | Best for |
|---|---|---|---|---|
| Manus (baseline) | None listed — paid from $20/mo | No | At Send — message "saved until you log in" | The original agent, if you'll pay |
| Kimi | Free plan (account required) | No | At submit — login dialog (WeChat / phone / SSO) | Agent tasks after sign-up |
| Genspark | Free tier (numbers behind login) | No | At submit — "log in or sign up" wall | Slides / sheets / docs workspace, after sign-up |
| MiniMax Agent | Free tier listed (models marked "Limited") | No | Send redirects to the MiniMax login page | Trying MiniMax models, after sign-up |
| EaseMate | 30 credits on sign-up; chat free anonymously | Chat only — no browsing or execution | Agent page demands sign-in; chat stays open | Anonymous chat answers, not agent tasks |
| AgentOne | 100 credits/mo, no card (per its FAQ) | Not verified — desktop app only | No web task entry at all | Desktop users willing to install an app |
The task, given verbatim to all six: "Compare the current prices of Notion, Obsidian, and OneNote for individual users based on their official pricing pages, and present the result as a short comparison table." Verified October 2026. No accounts were created; a tool passed only if it browsed and produced the table anonymously.
Kimi: the input is open, the submit is not
Kimi's homepage is the most inviting of the five — a live chat box that literally suggests you "ask anything, or do an Agent task." We did. The moment the task was submitted, a login dialog replaced it, offering WeChat QR, phone number, or enterprise SSO. No anonymous quota figures are published anywhere a visitor can see them. Kimi may well be a fine Manus alternative with an account; as a no-sign-up one, it scores zero, because the door is the submit button.
Genspark: a workspace behind the same wall
Genspark's pitch is a whole AI workspace — slides, sheets, documents — and its homepage input accepts a task just like Manus's does. Submitting ours produced a "log in or sign up" wall (Google, Apple, or more options) before any work began, and its credit numbers live behind that login too, so an anonymous visitor cannot even learn what the free tier contains. Whatever Genspark's free tier is worth, it starts after registration.
MiniMax Agent: send means sign in
MiniMax Agent doesn't bother with a dialog: pressing Send on its command-style input ("Enter message... use / for commands") navigates the whole page to MiniMax's account login — email, Google, or GitHub. Its plan comparison does show a Free column with models such as M3.1 Flash marked "Limited," which at least confirms a free tier exists. What it contains in credits, an anonymous visitor is not told.
EaseMate: the chat is open, the agent is not
EaseMate is two products wearing one name. Its Agent page walls exactly like the others — "Sign in to EaseMate AI Assistant," with 30 free credits offered as the sign-up bait. Its AI Chat, though, is genuinely anonymous, and it did produce a Notion / Obsidian / OneNote table for us. Read the fine print it added itself: the prices were "as of early 2025," with a suggestion to verify on official sites. That's a chatbot answering from memory — useful, but it is not an agent browsing pricing pages, and on a task whose entire point is current prices, the distinction is the product. One more note: EaseMate is often described as offering 200k free chat tokens a day; on this visit, that figure appeared neither on its chat FAQ nor its pricing page, which instead lists 30 credits on sign-up.
AgentOne: no-account, but also no web app
AgentOne's FAQ is the boldest claim here: "You can even use AgentOne without an account," with 100 free credits a month, "free forever, no credit card needed," and a download page headed "No Sign-up Required." The catch is delivery: AgentOne is, in its own words, "a real desktop app, not a browser tab." There is no web task entry to test — "Get started" leads to a sign-up page — so the anonymous claim can only be checked by installing software. Our rule is the same as always: what we cannot walk through end-to-end, we label not verified rather than repeat as fact.

FAQ
Is there a free Manus alternative that works without sign up?
Not as of October 2026. We gave Kimi, Genspark, MiniMax Agent, EaseMate, and AgentOne the same real task with no account; every one demanded sign-in before executing it. EaseMate's anonymous chat answered from the model's memory — it produced a table but did not browse or run the task, and dated its own prices to early 2025.
Is Manus itself free?
No. Manus's pricing page lists paid plans only, starting at $20/month. You can type a task on its homepage without an account, but pressing send only saves the message — Manus tells you it will be sent after you log in.
Which free Manus alternative is most generous if I do sign up?
Of the numbers published openly, AgentOne's free plan is the clearest: 100 credits a month, free forever, no credit card — though it is a desktop app we could not verify in a browser. EaseMate gives 30 free credits on sign-up. Genspark and MiniMax keep their free-tier numbers behind the login wall.
What can I use with no account for agent-style tasks?
A no-sign-up chatbot can draft answers from its own knowledge — EaseMate's chat produced a comparison table anonymously, while admitting its prices were from early 2025. For live, source-checked work, no anonymous agent we have tested will browse and execute for you. The chatbots in our directory are the current no-account ceiling.
