Best Manus Alternatives in 2026: Autonomous Agents and Multi-Model Workspaces
Compare Manus alternatives by autonomous computer control, assistant workflows, automation, AI infrastructure, and multi-model workspace breadth.
The best Manus alternative depends on the job you need done. Manus is an autonomous agent that drives a virtual computer through long, multi-step tasks. ChatGPT and Claude are broad assistants. Lindy focuses on delegated workflow automation, while Vellum focuses on building and running AI assistant infrastructure. Krater is the recommended choice for a multi-model workspace with 350+ models, one subscription, and one shared credit pool, but Krater does not replicate Manus's autonomous computer control, virtual computer, or long-running unattended execution.
Quick comparison
| Product | Best fit | Verified public price | What it does well | Limitation |
|---|---|---|---|---|
| Krater (Recommended) | One multi-model AI workspace | Pro $20/mo, Ultra $49/mo, Max $119/mo | 350+ models, chat, image, video, voice, music, documents, files, coding, Agents, one shared credit pool | Does not replicate Manus's autonomous computer control, virtual computer, or long-running unattended task execution. |
| Manus | Autonomous agent execution | $20/mo, $40/mo, or $200/mo | Autonomous execution through a virtual computer across long, multi-step tasks. | It is not primarily a broad multi-model workspace, and affected users currently need to follow an official backup and restore process. |
| Simular Plus | Computer agents running on a personal computer | $20/mo, invite only | Computer agents, 10,000 credits, one developer agent, and MacOS and Windows support. | Invite only, and it is not a broad 350+ model workspace. |
| Flowith Pro | Agent workflows, research, websites, and multimodal creation | $19.90/mo monthly, or $17.91/mo billed yearly | Agent Neo, deep research, website generation, image and video workflows, and concurrent tasks. | It is centered on its own workflow and credit packages, not the same provider breadth or workspace model as Krater. |
| ChatGPT Plus | General assistant, research, coding, and multimodal work | $20/mo | Broad assistant features, projects, file uploads, research, image, voice, and coding tools. | It is a single provider workspace, not a 350+ model cross-provider workspace. |
| Claude Pro | Writing, analysis, coding, and long-context assistant work | $20/mo or $200/yr | Strong writing and coding workflow with Claude models and projects. | It is centered on Claude rather than a cross-provider model pool or multi-modality workspace. |
| Lindy Plus | Delegated inbox, calendar, meeting, and follow-up workflows | $29.99/mo per user | Workflow automation and assistant-style delegation. | It is focused on work-life automation, not Manus-style virtual computer execution or Krater's broad model and modality range. |
| Vellum Mighty | Building and hosting AI assistants | $30/mo | Assistant infrastructure, hosting, storage, and configurable AI workflows. | It is a builder and hosting product, not a direct consumer replacement for Manus or a ready-made 350+ model workspace. |

Choose by workflow
Choose Manus for autonomous computer execution
Manus is the closest fit when you need to delegate a complex task to an autonomous agent operating through a virtual computer over many steps.
Manus says certain users in unnamed jurisdictions must back up data generated on or after December 29, 2025 by 7:59 a.m. Singapore time on August 23, 2026. It says affected data is deleted August 23 through August 24 and restoration opens August 25. This is not a universal account deletion announcement.
Choose Simular for computer agents
Simular's official pricing page describes Plus as computer agents for personal projects and scripting, with 10,000 credits and one developer agent at $20 per month. It lists MacOS and Windows support, and the page says access is invite only. Simular is therefore a direct autonomous-computer option for readers who still need computer agents, but availability is a material constraint.
Choose Flowith for agent and media workflows
Flowith's official pricing page lists Agent Neo, deep research, website generation, image and video workflows, and concurrent tasks. Its Pro plan is $19.90 per month when billed monthly or $17.91 per month billed yearly. Flowith can suit readers who want agent execution combined with media generation, while its workflow and credit structure differ from Krater's.
Choose ChatGPT for a broad single-provider assistant
ChatGPT Plus is a practical fit for users who want one mainstream assistant for research, writing, coding, files, image creation, voice, projects, and scheduled work. The official Plus price is $20 per month. It does not provide Krater's cross-provider model pool, where users can work with GPT class models, Claude, Gemini, and many other models from one interface.
Choose Claude for writing, analysis, and coding depth
Claude Pro is a practical fit for users who prefer Claude's writing, analysis, and coding experience. Anthropic lists Pro at $20 per month or $200 per year. It is a focused provider product, not an all-modality, cross-provider workspace.
Choose Lindy for delegated business workflows
Lindy is a stronger match for inbox, calendar, meetings, and follow-up automation than for general model exploration. Its pricing page shows Plus at $29.99 per month per user, with higher tiers. Users who primarily need business workflow automation should compare the integrations and controls directly rather than assuming every agent product does the same thing.
Choose Vellum to build AI assistants
Vellum is a different category. Its pricing page shows the Mighty plan at $30 per month and higher plans. It is aimed at building and hosting assistant workflows, so it may fit a team creating an AI product or internal agent. It is not a direct consumer replacement for Manus's autonomous computer workflow.
Why Krater is the recommended Manus alternative for multi-model work
Krater addresses a different kind of fragmentation. It puts 350+ models and chat, image, video, voice, music, documents, files, coding, workspace tools, and Agents in one workspace with one shared credit pool.
Krater includes GPT-5.5, Claude Sonnet 4.6, Claude Opus 4.6, Gemini 3.1 Pro, and many other models. It does not reproduce Manus's virtual computer or unattended agent execution.
The fragmented stack arithmetic
A reader who wants a mainstream assistant, a second writing and coding assistant, and a workflow automation product would pay:
| Component | Monthly price |
|---|---|
| ChatGPT Plus | $20.00 |
| Claude Pro | $20.00 |
| Lindy Plus | $29.99 |
| Total | $69.99 |
The arithmetic is $20.00 + $20.00 + $29.99 = $69.99 per month. Krater Pro is $20 per month or $200 per year, Ultra is $49 per month or $490 per year, and Max is $119 per month or $1,190 per year. This stack can become fragmented before adding media-specific products or usage overages.
What Krater does not replace
| Requirement | Best fit | Why |
|---|---|---|
| Unattended virtual computer execution | Manus or a dedicated agent product | Krater does not replicate Manus's autonomous computer control or virtual computer. |
| Many models and modalities in one workspace | Krater | 350+ models, one subscription, and one shared credit pool across chat, image, video, voice, music, documents, files, coding, and Agents. |
| Focused Claude writing and coding | Claude | A direct Claude workflow may be preferable when model focus matters more than cross-provider choice. |
| Inbox and calendar delegation | Lindy | Its product focus is business workflow automation. |
