Quick verdict
Bottom line: Manus is a strong general AI agent, but its credit pricing is hard to predict — a single deep-research task can burn 500–900 credits, about a quarter of the $20 plan’s 4,000 monthly credits. The best alternatives are Genspark for polished deliverables, ChatGPT Agent if you already pay for ChatGPT, and OpenManus if you want the same idea free and self-hosted.
Why do people look for Manus alternatives?
People usually leave Manus for the bill, not the quality. Paid plans run $20/month for 4,000 credits, $40 for 8,000, and $200 for 40,000, credits do not roll over, and you often do not know a task’s cost until it finishes. The free plan is also thin — about 300 refresh credits a day and one task at a time. Others want an agent that lives in tools they already use, or one they can run on their own machine.

What are the 8 best Manus alternatives?
1. Genspark — closest Manus-style rival
Genspark routes work across many models and returns finished deliverables — slides, sheets, and research — much like Manus. Free daily credits; Plus is $24.99 a month (or $19.99 billed annually). The easiest lateral move from Manus.
2. ChatGPT Agent — best if you already pay for ChatGPT
ChatGPT’s agent mode browses and completes multi-step tasks inside ChatGPT, on Plus at $20 a month. No agent access on the free tier, and tasks are capped monthly. If you already pay for Plus, try this first.
3. Lindy — best for business workflows
Lindy builds agents for recurring team work — inbox triage, scheduling, and processes that run inside Slack and your other apps. Pricing is $29.99 per user a month. It is less a one-off research agent than a standing employee for repeatable business tasks.
4. OpenManus — best free, self-hosted option
OpenManus is an open-source, Manus-style agent framework you run yourself in Python, free apart from your own model API costs. That removes the subscription and credit meter entirely — but you need technical skill to install and supervise it.
5. CrewAI — best for multi-agent teams
CrewAI lets developers assemble teams of specialised agents that hand work to each other. The framework is free and open source, with enterprise pricing for its managed platform. A builder’s tool — non-coders should pick Genspark or ChatGPT Agent.
6. n8n — best for repeatable workflows
n8n will not improvise a research report, but for tasks you repeat — scrape, summarise, file, notify — its defined workflows are cheaper and more predictable than any credit-metered agent. Self-hosting is free, and cloud plans start at $20 a month. Many users split work: n8n for the routine, a chat model for one-offs.
7. AutoGPT — best for autonomous-agent tinkerers
AutoGPT is one of the original autonomous agent projects: free to self-host, with a cloud version at $42.50 a month for people who do not want to run servers. It runs agents on a schedule and chains goals, with rougher edges than Manus.
8. Devin — best for software tasks
If your Manus use was mostly coding, Devin is the specialist: an autonomous software engineer working through tickets in a real dev environment. Free tier; paid from $20 a month. It does one job, code, far more deeply than a general agent.
Verdict: which Manus alternative should you pick?
Choose Genspark for the closest like-for-like swap, ChatGPT Agent if a Plus subscription is already in your budget, and OpenManus if price is the whole problem and you can self-host. Pick Lindy or n8n when your tasks repeat on a schedule. Stay with Manus if you rely on Wide Research — nothing else here spreads one task across hundreds of parallel items the same way.
Frequently asked questions
How much does Manus cost?
Paid plans are $20 a month for 4,000 credits, $40 for 8,000, and $200 for 40,000, with a limited free plan offering about 300 refresh credits a day. Credits do not roll over.
What is the best free alternative to Manus?
OpenManus — free and open source, though you pay for your own model API usage and need technical skill. Genspark’s free daily credits are the best no-setup option.
Why do Manus credits run out so fast?
Complex tasks take many browser and code steps, and each step costs credits. Reviewers report deep-research tasks using 500–900 credits, so a handful of heavy jobs can empty the $20 plan.
Is ChatGPT Agent as good as Manus?
For browsing and everyday multi-step tasks inside ChatGPT, it is close, and it is already included with Plus. Manus still leads for parallel Wide Research and scheduled, deliverable-focused work.
