SmythOS

SmythOS is an AI agent platform for building, managing, and deploying agents through visual tools or conversational prompts. It is best suited to teams that need multiple ways to connect and host agents; buyers should weigh its API quotas and separate model charges against those needs.

Overview

SmythOS brings agent creation, observation, and deployment together. Its Studio provides a drag-and-drop canvas, while Agent Weaver can create, troubleshoot, and update workflows from prompts. This combination makes it a practical fit for both visual builders and teams that prefer to describe workflow changes conversationally. It is less compelling for buyers seeking a simple, fixed-cost product: built-in model usage is billed separately, and plan quotas vary substantially.

Key features

Agent creation and integrations

The visual builder lets users assemble agents and workflows without code; Agent Weaver adds a prompt-based way to create and revise them. Prebuilt connections include Slack, Trello, GitHub, and Stripe, with OpenAPI and Postman collection support for connecting other services. Support for OpenAI and Anthropic models, Hugging Face models, and customer-provided models gives teams options, but does not remove separate usage charges for built-in models.

Deployment and security

Agents can be deployed through chat, APIs, webhooks, MCP servers, and ChatGPT, or exported to run locally. SmythOS also supports local, on-premises, and VPC deployment, including keeping data within a customer's environment. Its security approach describes zero-trust access controls, least privilege, fine-grained ACLs, and isolated agent contexts. For its SaaS service, data in transit uses TLS 1.2+ and data at rest is encrypted using the cloud provider's KMS. HashiCorp Vault and AWS Secrets Manager integrations support secret management. These controls and deployment choices suit organizations with specific security or hosting requirements; customers should distinguish SaaS protections from the additional control of self-hosting.

Runtime and scheduled work

The open-source Runtime Environment and SDK include more than 40 components for production agents. Scheduled runs and web browsing are supported, making the platform relevant to workflows that need timed execution or web access.

Pricing

SmythOS has free and paid options, but the plan names and terms matter: Public and Public Free are separate free offerings, while Builder and Private Builder are separate paid plans. Built-in model usage is billed separately according to usage except where a plan states a model usage discount or credit. Compare those charges with the included credits and any discount before estimating total cost.

• Public: free, billed Totally Free. Includes $5 in free credits per month, one seat, public agents, a visual agent IDE, bring-your-own-model support, and free local deployment. Model usage costs 2.5x. This is the clearest starting point for an individual who can work with public agents and wants to try local deployment; the higher model cost and public-agent limitation make it a weaker fit for private team workflows.
• Public Free: free, billed monthly, with one seat. It is a no-cost option for a solo user, but the plan terms provide fewer stated inclusions than Public.
• Builder: $39 a month, billed monthly, with 100 fast API calls per day. This is the entry paid plan for modest API use, but its daily quota is far below the higher tiers.
• Private Builder: $39 a month, billed per seat/month. It includes $20 in free credits per month, a 40% model usage discount, 100 fast API calls per day, private agents, and unlimited Weaver AI messages. It suits a solo builder who needs private agents and frequent prompt-based workflow work, though API capacity remains limited.
• Startup: $399 a month, billed per month. It includes $200 in free credits per month, a 50% model usage discount, 5,000 fast API calls per day, 10 team spaces, three seats, RAG Agents, and collaboration features. The larger quota and team tools suit a small group with sustained agent activity, but the plan remains capped at three seats.
• Scaleup: $1,499 a month, billed starting at $1,499 per month. It includes $300 in free credits per month, a 60% model usage discount, 25,000 fast API calls per day, 50 team spaces, five seats, a forward deployed engineer, priority support, and white labeling. It fits teams that need substantially more API capacity and priority assistance; five seats still limits larger teams.
• Enterprise: $4,955 a month, billed starting from $4,955 per month. It includes a 100% model usage discount, unlimited agents, tasks, fast API calls per day, team spaces, and seats, plus on-premises and VPC deployment, OEM distribution, compliance tailoring, and custom retention policies. This is aimed at organizations requiring broad capacity and deployment or compliance controls; the starting price makes it a poor match for small or occasional projects.

Support ranges from community support to personal priority and team priority support, with forward deployed engineer support on higher tiers. The 100 daily calls on Builder and Private Builder are a meaningful constraint for production workloads, while Startup and higher tiers raise that ceiling at a steeply higher subscription price.

Platforms

SmythOS supports API, Linux, macOS, self-hosted, web, and Windows environments. This range supports teams working across hosted and local setups, including those that need to run agents within their own infrastructure.

Who it's for

SmythOS is a strong match for teams building AI agents that need visual and prompt-driven workflow creation, integrations, and several deployment paths. Public can serve individuals exploring the platform, while Private Builder adds private agents and discounted model usage for a solo paid user. Teams should consider Startup or Scaleup when seat and API limits become restrictive. Organizations needing on-premises or VPC deployment, unlimited seats, or tailored retention have a clearer case for Enterprise. It is less suitable for users who need predictable all-in costs or only a small API quota.

Pros and cons

• Pro: Visual Studio and Agent Weaver offer two distinct ways to create and maintain workflows, serving both canvas-based builders and prompt-first users.
• Pro: Chat, API, webhook, MCP, ChatGPT, and local deployment options accommodate different ways of delivering agents.
• Pro: Self-hosting, VPC, and on-premises support, alongside access controls and vault integrations, give security-conscious organizations deployment and credential-management choices.
• Con: Built-in model usage is generally charged separately, so the subscription price alone does not show the full cost.
• Con: Builder and Private Builder cap fast API calls at 100 per day, which can constrain heavier use.
• Con: Seat limits on Startup and Scaleup are three and five respectively, so growing teams may need a higher tier.

Alternatives

Consider these alternatives if their platform focus or plan structure better fits your project:

• Microsoft Copilot is a freemium option for readers seeking an app across web, Windows, macOS, iOS, and Android; its Free plan has limited access subject to capacity and usage limits.
• Vellum offers a free starting point with first tasks included and pay-as-you-go credits, and a $30/month Mighty plan; consider it when that credit-based entry better suits your workflow.
• Camunda has a free Self-Managed Development plan for local development and testing; consider it when that development scope is the priority.
• Flowise has a free plan with 2 Flows & Assistants, 100 Predictions / month, and 5MB Storage; consider it for a smaller free allocation of flows and predictions.
• Google Agent Development Kit is a free, open-source framework; consider it when a framework rather than SmythOS's paid orchestration plans is the better fit, bearing in mind that model and cloud service usage may require separate access or billing.
• Houston has a free personal workspace for up to three people and includes access to its integrations; consider it if that team size and workspace model suit your needs.
• Retool offers a free plan and a Team plan priced at $10/mo per builder and $5/mo per internal user; consider it when that per-user pricing better matches your team.
• Helios offers a free plan with 5,000 starting credits and community support; consider it if that credit-based free entry is a better match.

Verdict

Choose SmythOS if your team needs flexible agent creation and deployment, particularly when self-hosting, API delivery, or workflow integrations matter. Its strongest case is the range of build and deployment routes paired with enterprise hosting controls. Look elsewhere if you need a predictable total cost or a generous low-tier API quota: model usage can add to the subscription, and the entry paid plans allow only 100 fast API calls per day.
