> Looking for Manus alternatives that fit an engineering team's actual workload? Here is how Genspark, Devin, Replit Agent, and Suna stack up on price and scope.

## Alternatives to manus-ai

**Winner:** genspark

**Verdict:** Genspark is the closest one-for-one Manus swap if you want the same breadth at a similar price. Pick Devin or Replit Agent instead when the tasks you actually run are engineering work, and pick Suna when owning the agent's code matters more than a polished onboarding flow.

**Methodology:** We evaluated each agent hands-on against a shared task set (a multi-source research summary, a small full-stack app, and a routine code migration) between June 30 and July 14, 2026, then cross-checked pricing and feature claims against each vendor's own pricing page, plus community reviews (Reddit, G2-style writeups) for real-world cost reports where official pricing was gated behind a signup wall. Screenshots were captured directly from each product's live homepage. Scores (0-5) weigh task completion quality, pricing transparency, and team readiness equally; we did not run a formal benchmark suite, so treat scores as a structured opinion, not a lab result.


### Criteria

| Criterion | genspark | devin | replit-agent | suna |
|---|---|---|---|---|
| Pricing | Free tier + ~$20-$200/mo credit plans | ~$500/seat/mo (Team), custom Enterprise | Free tier + $18-100/mo plus usage credits | Free, self-hosted (pay only your own LLM/compute) |
| Task scope | Browser, slides, docs, image, video, code, calls | Code only: PRs, migrations, triage, CI fixes | Full-stack web apps: scaffold, code, deploy | Browser, shell, files: general research and coding tasks |
| Deployment | Hosted SaaS only | Hosted SaaS (cloud dev environment) | Hosted SaaS (Replit cloud IDE) | Self-hosted, or Kortix-managed hosted option |
| Team collaboration | Individual-first; office-suite plugins for sharing | Built for teams: GitHub, Linear, Slack integrations | Up to 5-15 collaborators depending on plan | Community-driven; team setup depends on self-host config |
| Cost predictability | Pricing gated behind login; approximate only | ACU consumption hard to estimate before the job runs | Effort-based billing, variable with build complexity | Predictable once self-hosted; you control compute spend |

### Per-product notes

- **suna** — best for: Teams that want to audit, self-host, and control an autonomous agent, score: 3.9/5
  The pick for teams that want an auditable, self-hosted agent over a black box.
- **devin** — best for: Engineering teams delegating recurring migrations, PR review, or maintenance, score: 4.1/5
  The right swap only if the Manus tasks you actually run are engineering work.
- **genspark** — *Closest overall swap*, best for: Teams that want Manus's breadth without switching how they think about the agent, score: 4.3/5
  The closest like-for-like swap for Manus's breadth, at a comparable credit-based price.
- **manus-ai** — best for: Individuals and small teams who want one agent to deliver a finished file, score: 4.2/5
  Still the default pick for general research-to-deliverable work; look elsewhere for narrower needs.
- **replit-agent** — best for: Developers who want a deployed app from a prompt, not a written report, score: 4/5
  Best swap when what you actually want from Manus is a deployed app, not a report.

## FAQ

### Is there a direct one-to-one replacement for Manus?

Not exactly. Genspark comes closest in scope (browser, slides, docs, image, video, code from one prompt), but every alternative here trades some of Manus's breadth for depth in a narrower lane.

### What is the cheapest Manus alternative?

Suna, since the core agent is free and open source; you only pay for the compute and LLM API calls you connect to it. Replit Agent's free Starter tier is the cheapest hosted option.

### Which Manus alternative is best for a small engineering team?

Devin if the work is genuinely recurring code migrations or maintenance and the $500/seat/month clears budget; Replit Agent if the goal is shipping a deployed app quickly; Suna if the team wants to self-host and audit the agent.

### Can I self-host any of these like Manus's competitors claim?

Suna is the only fully self-hostable option in this comparison. Genspark, Devin, and Replit Agent are hosted SaaS products with no self-hosted deployment path.

### Do any of these alternatives handle non-coding tasks like Manus does?

Genspark and Suna both handle general browser research, document generation, and file tasks similar to Manus. Devin and Replit Agent are scoped specifically to software engineering and app building.

### Why isn't Cursor or GitHub Copilot on this list?

Those tools augment a developer who is already writing code in an editor. Manus and the four alternatives here run multi-step tasks autonomously with minimal supervision, which is a different job.

### Is Devin worth $500 a month per seat?

Only if you can point it at real recurring work, migrations, PR review, or maintenance chores that would otherwise cost more in engineering hours than the subscription. For occasional use, it's expensive relative to the alternatives here.
