# Manus AI Alternatives 2026: 4 Agents Worth Testing URL: https://notificationharbor.com/compare/manus-ai-alternatives-2026 Type: comparison Locale: en Published: 2026-07-29 Updated: 2026-07-30 --- > Four Manus AI alternatives tested on pricing, concurrency, and real output: ChatGPT Work, Devin, Lindy AI, and OpenManus, each built for a different job. ## Alternatives to manus-ai **Winner:** chatgpt-work **Verdict:** ChatGPT Work is the closest general-purpose substitute for Manus's finished-file promise, and the safest starting point if your team already pays for ChatGPT, though it is new enough that its own reputation is still forming. Devin beats everything here on code specifically, at a price only engineering teams can justify. Lindy AI is not really competing on the same axis: pick it when the job is recurring inbox and calendar ownership rather than one-off research. OpenManus is the only option that hands you full data control for zero subscription cost, in exchange for owning the operations yourself. None of the four fully duplicates Manus's browser-plus-terminal-plus-files combination in one hosted product, but each one replaces the specific slice of it you are actually likely to use. **Methodology:** We pulled live homepage screenshots and current pricing pages for all five products in July 2026, cross-checked published concurrency and credit or ACU limits against each vendor's own pricing page, and read G2, Reddit, and GitHub threads for failure modes vendors do not surface on their landing pages. Custom scores are directional, built from the frequency and tone of independent user reports rather than one shared benchmark, since none of these vendors publish a common task-completion metric. Where a figure could not be confirmed on the vendor's own site, we said so instead of estimating it. ### Criteria | Criterion | chatgpt-work | devin | lindy-ai | openmanus | |---|---|---|---|---| | Entry pricing | Bundled in Plus at $20/month; heavier agentic runs are metered by task complexity, full-speed access leans on Pro at $100 or $200/month | No meaningful free tier; Team runs about $500/seat/month with Agent Compute Units billed at $2.00 to $2.25 each | Plus $49.99/month (2 inboxes); Pro $99.99/month unlocks computer use; Max $199.99/month (5 inboxes); 7-day free trial on Plus | Free and MIT-licensed, self-hosted; real cost is your own compute plus whatever LLM API key you connect | | What it actually runs | Agent mode inside ChatGPT (GPT-5.6): pulls context from connected apps via @ mentions, ships finished docs, sheets, slides, dashboards, small web apps | Cloud dev environment (shell, browser, editor) scoped to engineering: implements, tests, debugs, opens PRs | No-code agent for recurring admin work: inbox triage, scheduling, meeting notes, follow-ups, reachable by SMS/iMessage | Open-source general agent, optional DataAnalysis agent, Playwright browser automation and code execution on your own machine | | Concurrent / parallel work | No published hard number; usage ceiling scales with plan, roughly 5x on $100 Pro and 20x on $200 Pro versus Plus | Multiple Devins run in parallel on Team/Enterprise, each consuming its own ACU allotment | Scales by plan tier rather than a concurrency cap; computer-use automation gated to Pro and above | Limited only by the compute you provision yourself; no vendor-imposed cap | | Self-hosting / data control | No, closed SaaS inside ChatGPT; data handling follows OpenAI's Plus or Enterprise terms depending on plan | No, runs in Cognition's cloud dev environment; enterprise agreements available for data terms | No, closed SaaS; Enterprise tier adds HIPAA, SSO, SCIM, and audit logs for regulated teams | Yes, fully self-hostable, MIT-licensed, 57.8k GitHub stars | | What you get back | Same deliverable classes as Manus: documents, spreadsheets, slides, dashboards, small web apps | Reviewable pull requests and shipped code, not documents or slide decks | Actions taken on your behalf (replies sent, meetings booked, inbox labeled), not standalone files | Same output classes as Manus, shaped by whichever agent and tools you wire up yourself | ### Per-product notes - **devin** — best for: Engineering teams with recurring migration, refactor, or maintenance work, score: 4.1/5 The strongest pick if the deliverable you actually want is shipped code, not a document. - **lindy-ai** — best for: Teams that want an AI assistant to own recurring inbox, scheduling, and follow-up work, score: 4.2/5 Best when the job is running your inbox and calendar, not producing a one-off research artifact. - **manus-ai** — best for: Individuals and small teams who want one agent to research and hand back a finished file, score: 3.8/5 Still the broadest single-product match for research-to-file tasks, but opaque pricing and an unresolved ownership situation are real reasons people go looking elsewhere. - **openmanus** — best for: Developers who want Manus's virtual-computer pattern with zero subscription cost and full data control, score: 3.7/5 The right call only if you have the ops capacity to run and maintain it yourself. - **chatgpt-work** — best for: Teams already paying for ChatGPT who want agentic, finished-deliverable tasks without a new subscription, score: 4/5 Closest functional match to Manus's finished-deliverable promise, from a vendor most teams already trust, but young enough that its own reputation is still being written. ## FAQ ### What is the closest alternative to Manus AI in 2026? ChatGPT Work is the closest general-purpose match: it ships the same deliverable classes as Manus (documents, spreadsheets, slides, small web apps) from a vendor most teams already pay for, though it launched July 9, 2026 and is still building its own track record. ### Is there a free or open-source alternative to Manus AI? OpenManus is the closest free option: an MIT-licensed, self-hosted agent framework with 57.8k GitHub stars that replicates Manus's browser-plus-terminal-plus-files approach. You provide your own compute and LLM API key, and there is no managed support. ### Why are people looking for Manus AI alternatives right now? Two reasons: China's regulator blocked Meta's roughly $2 billion planned acquisition of Manus in April 2026, leaving its ownership and roadmap unsettled, and Reddit/Trustpilot threads document unpredictable credit consumption, with some single tasks burning 900+ credits. ### Which Manus alternative is best for coding tasks? Devin, built by Cognition, is scoped specifically to software engineering: it implements, tests, debugs, and opens pull requests inside its own cloud dev environment. It costs roughly $500 per seat per month and does not produce documents or slide decks. ### Can Lindy AI replace Manus for research tasks? Not directly. Lindy is built for recurring admin work like inbox triage, scheduling, and follow-ups rather than one-off research-to-document tasks. It is a better fit once you need an assistant that keeps running after initial setup. ### How much does ChatGPT Work cost? ChatGPT Work is bundled starting on the $20/month Plus plan, with heavier agentic runs metered by task complexity. Full-speed access leans on the $100 or $200/month Pro tiers, which raise the usage ceiling roughly 5x and 20x over Plus. ### Is Manus AI still owned by Meta? No. China's National Development and Reform Commission blocked Meta's planned acquisition in April 2026 after an antitrust probe. Manus employees had already begun moving to Meta's AI org and early backers had been paid out, so the practical unwinding of the deal is still unresolved. ### Do any of these Manus alternatives support self-hosting? Only OpenManus. ChatGPT Work, Devin, and Lindy AI are all closed SaaS products; OpenManus is MIT-licensed and fully self-hostable, though you take on uptime, patching, and API key management yourself.
