10 Best AI Agent Builders of 2026

This list is for operations and product teams choosing a platform to build AI agents and comparing what each one costs to run. Vendors bill in different units: MindStudio charges a flat fee plus model usage, Zapier counts activities, Lindy, Gumloop and Microsoft count credits, n8n counts workflow executions, Dify counts message credits, and Botpress and Chatbase charge by conversation or message. Tools are ranked by value first, then features, then ease of use. Prices are the cheapest paid plan in USD as shown on each vendor's page on the check date; where a page showed another currency from our location or no price at all, the price is marked pending.

   MindStudio

   8.6/10

   A no-code agent builder with a free one-agent plan and an Individual plan that adds unlimited agents and runs for a flat fee plus model usage.

   Price

   Free plan with one agent and 1,000 runs a month; Individual $16 per month billed yearly or $20 monthly, plus usage

   Best forOperations and product teams that want to build many internal agents without paying per run.

   MindStudio ranks first on this list because it separates the platform fee from the number of runs. The Free plan covers one agent and 1,000 runs a month, and the Individual plan removes both limits for $20 a month, or $16 a month when paid yearly. You still pay for model usage, but MindStudio routes requests to 200+ models without asking for your own API keys, and you can connect your own keys if you prefer. That makes it a cheap place for an operations or product lead to prototype a research agent, a content checker or a ticket summarizer and keep it running. Team features sit on the Business plan, which is quoted on request and adds a shared workspace, unlimited collaborators, SSO, audit logs, budgets and alerts, plus the option to self-host. We compared documented features and published prices and did not run a trial account.

   • ✓Lowest verified paid price on this list at $16 a month billed yearly
   • ✓Runs are unlimited on Individual, so the bill does not grow with run count
   • ✓No API keys needed to try many models

   • ✕Model usage is billed on top of the plan fee
   • ✕Team workspaces and SSO need the custom-priced Business plan
   • ✕Individual plan is aimed at a single builder rather than a shared team

   Free plan:

   Yes, one agent and 1,000 runs a month

   Cheapest paid plan:

   Individual, $16 a month billed yearly or $20 monthly

   Billing unit:

   Flat plan fee plus model usage

   Models:

   Bottom line: MindStudio gives the most agent capacity per dollar here, with unlimited agents and runs from $16 a month. Teams that need shared workspaces and SSO should budget for a Business quote.

   Zapier Agents

   Zapier's agent product, priced by activities, that can act in the apps you have connected to Zapier and browse the web.

   Best forTeams that already run Zapier automations and want agents that act in the same connected apps.

   Zapier Agents is the easiest starting point for teams whose apps are already connected to Zapier. It is priced separately from Zaps: the free tier gives 400 activities a month and Agents Pro gives 1,500 for $400 billed annually, which works out to $33.33 a month. Zapier defines an activity as an action an agent takes in a behavior or chat, a web browse or a lookup in attached knowledge, so a single request can use several. Agents can only act in the apps you have connected and through the triggers and actions you have set up, which limits risk and keeps setup short. On a Zapier Team account the whole team shares one activity pool. The Enterprise tier adds agent sharing across the organization and audit logs, although the FAQ notes Agents does not currently honor app restrictions on Zapier Enterprise accounts. We compared documented features and published prices and did not run a trial account.

   • ✓Permanent free tier is enough to test real tasks
   • ✓Agents use the triggers and actions you have already set up in Zapier
   • ✓Team accounts share one pool of activities

   • ✕1,500 activities on Pro can run out quickly because chat actions, browsing and knowledge lookups all count
   • ✕Zapier says Agents does not yet support Enterprise app and action restrictions
   • ✕Feature set is narrower than dedicated builders such as Dify or n8n

   Free plan:

   Yes, 400 activities a month

   Cheapest paid plan:

   Agents Pro, $33.33 a month billed annually

   Billing unit:

   Paid allowance:

   Enterprise:

   Bottom line: Zapier Agents is the quickest way to put an agent on top of existing Zapier connections, with a usable free tier. Watch the activity count, since browsing and knowledge lookups also use it.

   Lindy

   Best forTeams that want an assistant handling inbox, meetings and routine tasks rather than a visual builder.

   Lindy is less a blank canvas and more a ready-made teammate that lives in Slack, email and meetings. The Team plan starts at $29.99 a month for 3,000 credits, and every active user in the workspace is billed at that rate, with each seat adding its credits to a shared pool. Lindy's pricing page gives a rough guide to what work costs: everyday asks use 2 to 250 credits, deep research or support triage 250 to 1,000, and large builds such as dashboards 1,000 to 2,500. When the pool runs low Lindy pauses rather than charging overage, and admins can top up at $10 per 1,000 credits. Features include inbox management, meeting notes and scheduling, scheduled routines, 1,500+ integrations, MCP support and model choice per task. There is no permanent free plan, only $50 in credits that last 7 days. We compared documented features and published prices and did not run a trial account.

   • ✓Covers email, meetings and Slack without building workflows from scratch
   • ✓Credits from every seat go into one shared pool
   • ✓Lindy pauses instead of billing overage when credits run out

   • ✕No permanent free plan; the $50 credit grant lasts 7 days
   • ✕Every active user in the workspace is billed
   • ✕Larger jobs can use 1,000 to 2,500 credits each

   Free plan:

   Top-ups:

   Integrations:

   1,500+, plus MCP

   Bottom line: Lindy suits teams that want an assistant doing inbox and meeting work out of the box. Per active user billing makes it costlier than flat-fee builders as a team grows.

   Best forTechnical operations teams that want agents inside larger workflows and the option to self-host.

   n8n is the most flexible option here for teams that see agents as one part of a larger automation. Every cloud plan includes agents, MCP and AI nodes, and n8n bills per workflow execution with unlimited steps, so an agent that calls ten tools still counts once. Starter includes 2.5K executions a month, 5 concurrent executions and AI models without API keys; Pro raises that to 10K executions, up to 50 concurrent runs, admin roles, metric-based evaluations and workflow history. Business adds SSO, LDAP, multiple environments and Git version control, and a Startup plan cuts Business by 50% for companies under 20 employees. The standard Community Edition is free to self-host from GitHub. From our location the pricing page listed euros only, so we mark the USD price as pending. The editor assumes some comfort with data and APIs. We compared documented features and published prices and did not run a trial account.

   • ✓A long agent workflow counts as one execution
   • ✓Self-hosting keeps data on your own servers at no license cost
   • ✓Startup plan offers 50% off Business for companies under 20 employees

   • ✕Pricing page showed euros from our location, so the USD price is pending
   • ✕Steeper learning curve than chat-first builders
   • ✕Business plan is a big step up from Pro

   Billing unit:

   Bottom line: n8n is the strongest choice for technical teams that want agents inside multi-step workflows or on their own servers. Non-technical users will find chat-first builders quicker to learn.

   Best forProduct teams building customer-facing AI apps that need model choice, knowledge bases and an API.

   Dify suits product teams that want to ship an agent or chat app with its own knowledge base and API. Dify Cloud's Professional plan costs $590 per workspace per year and includes 5,000 message credits a month, 3 team members, 50 apps, 500 knowledge documents and 5GB of knowledge storage, along with 20,000 trigger events a month and no Dify API rate limit. Message credits work across OpenAI, Anthropic, Gemini, xAI and Tongyi models; once used up, you can switch to your own API key. The Team plan at $1,590 per workspace per year raises limits to 50 members, 200 apps and 10,000 credits. A free Sandbox plan lets you try core features with 200 message credits, and the open source Community Edition can be self-deployed with Docker. The interface is aimed at builders comfortable with prompts, retrieval and workflows. We compared documented features and published prices and did not run a trial account.

   • ✓One price per workspace rather than per seat
   • ✓Switch to your own API keys after included credits run out
   • ✓Self-hosted Community Edition for teams that want control

   • ✕Professional covers only 3 team members
   • ✕Built for developers and product teams more than business users
   • ✕Cloud pricing is shown as an annual figure

   Self-hosting:

   Bottom line: Dify is a strong value for product teams building AI apps with retrieval and an API, priced per workspace. Teams larger than three builders should look at the Team plan.

Developers get a Gumloop MCP and CLI. Enterprise adds SCIM and SAML, role-based access control, audit logs, custom data retention and a virtual private cloud option.

   Botpress prices its agents by conversation, which is easy to tie to support volume. The Free plan includes 100 conversations, 3 seats, 3 AI agents, a resolution SLA and a public help center. Plus costs $150 a month billed annually for 250 conversations, with extra packs of 100 for $65, or $0.65 a conversation. It adds unlimited AI agents, whitelabel webchat, a help center on your own domain, $25 of AI usage and live chat support. Each conversation includes $0.10 of AI usage covered by Botpress, and auto-recharge keeps agents running when you hit a limit. Team at $750 a month billed annually covers 1,500 conversations, unlimited seats, routing, RBAC, team analytics and real-time collaboration. The voice channel, uptime SLA and security review sit on Enterprise. For low volumes the per conversation rate is higher than credit-based builders. We compared documented features and published prices and did not run a trial account.

Add-ons are where costs climb: extra credits are $40 per 1,000, extra agents $25 each a month and removing the Chatbase branding $99 a month.

   Best forOrganizations on Microsoft 365 and Power Platform that need governed agents for staff and customers.

   Copilot Studio is the natural choice for organizations that already run on Microsoft 365 and Power Platform. It is sold as a tenant-wide license with capacity packs of 25,000 Copilot Credits at $200 per pack per month, and Microsoft also offers a pay-as-you-go meter with no up-front commitment and a pre-purchase plan of prepaid credit units. Credits are used whenever an agent completes an action or response, and the number per action varies. The standalone license lets you publish agents to websites, apps and social platforms, lets non-licensed users use them, and adds the GitHub Copilot harness. Builders can use prebuilt, premium and custom Power Platform connectors, Microsoft Foundry and Azure AI Search knowledge, Dataverse storage and IVR agent design. Admins manage agents, costs and ROI in the Power Platform admin center. Users with Microsoft 365 Copilot can already build internal agents at no extra cost. We compared documented features and published prices and did not run a trial account.

   • ✓Deep fit with Microsoft 365, Dataverse and Power Platform
   • ✓Agents can serve users without their own licenses
   • ✓Pay-as-you-go option avoids buying packs in advance

   • ✕$200 entry pack is expensive for small teams
   • ✕Credit cost per action varies, which makes bills harder to predict
   • ✕Setup and governance assume a Power Platform admin

    Best forLarger companies that want a managed program of agents with evaluations, SSO and an account manager.

    Relevance AI positions itself as a platform for building an AI workforce, meaning many agents that take on sales, support and operations work. The pricing page we checked lists a single Enterprise plan with custom actions and custom vendor credits, unlimited agents and tools, unlimited users and projects, unlimited workforces and 2,000+ integrations. It also includes calling and meeting agents, enterprise triggers, agent evaluations, A/B testing and analytics, plus SSO, RBAC, audit logs and a dedicated account manager. No self-serve price is published, so buyers need to talk to sales, and we mark pricing as pending. That model fits companies planning a broad rollout with measured outcomes, but it puts Relevance AI last on value for smaller operations and product teams comparing published task or credit prices. We compared documented features and published prices and did not run a trial account.

    • ✓Evaluations and A/B testing for measuring agent quality
