SmythOS

SmythOS is an AI agent platform for creating, observing, and deploying workflows. It suits teams that want visual or prompt-driven agent building with choices over integrations and hosting. Its breadth is useful, but usage caps and model charges make the subscription price only part of the buying decision.

Overview

SmythOS brings agent design and deployment into one platform, with a visual canvas for assembling workflows and Agent Weaver for creating or revising them through prompts. Teams can send agents to several destinations or run them locally. That flexibility is valuable for organizations with distinct deployment needs; it is less of a fit for buyers who prioritize predictable costs over control, since API quotas differ by plan and built-in model usage is charged separately.

Key features

Build agents and connect services

Studio’s drag-and-drop canvas lets users build agents and workflows without writing code, while Agent Weaver can create, troubleshoot, and update workflows from conversational prompts. These two approaches serve both visual builders and teams that prefer to describe changes. Prebuilt connections include Slack, Trello, GitHub, and Stripe, and OpenAPI and Postman collection support gives teams additional ways to connect services.

SmythOS supports models from OpenAI and Anthropic, Hugging Face models, and customer-provided models. That choice can help teams work with different model sources, but built-in model usage is billed separately from the subscription according to usage, so the plan’s monthly price is not the total cost of operation.

Deployment, security, and runtime

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, allowing data to remain in a customer’s environment. For its SaaS, data in transit uses TLS 1.2+ and data at rest is encrypted using the cloud provider’s KMS. Its security approach includes zero-trust access controls, least privilege, fine-grained ACLs, isolated agent contexts, and vault integrations for HashiCorp Vault and AWS Secrets Manager.

The Runtime Environment is described as an open-source runtime and SDK with more than 40 components. That gives production teams a runtime and SDK alongside the hosted agent-building platform. Scheduled runs and web browsing are also supported.

Pricing

The plan lineup includes several distinct tiers and seat allowances, so buyers should compare the specific offer to their intended deployment rather than assume all plans share the same features or limits. Public Free costs nothing, billed monthly, with one seat. Public is also free, billed Totally Free, with $5 in free credits per month, one seat, 2.5x model usage cost, Public Agents, Visual Agent IDE, Bring your own Model, and Free Local Deployment. Those free options provide a way to start, but the one-seat limit and, for Public, the higher model usage cost constrain their suitability for teams or sustained model use.

Builder is $39 a month, billed monthly, with 100 fast API calls per day. Private Builder is $39 a month, billed per seat/month, and adds $20 in free credits per month, a 40% model usage discount, 100 fast API calls per day, Private Agents, and unlimited Weaver AI messages. The private tier is the more relevant option for a buyer who needs private agents and prompt capacity; its per-seat term makes team cost depend on headcount.

Startup is $399 a month, billed per month, with $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. It is a stronger fit for a small team building beyond the entry-level call allowance, though the three-seat cap may be restrictive as teams grow.

Scaleup is $1,499 a month, billed starting at $1,499 per month, and 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. This tier suits larger deployments that need higher quotas and assistance, but it still has a five-seat allowance. Enterprise is $4,955 a month, billed starting from $4,955 per month, with 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. Its custom terms and higher starting price make it a fit for organizations requiring those capabilities, not a default upgrade.

Support ranges from community support to personal priority and team priority support, with forward deployed engineer support for higher tiers. Compare the plan’s call quota, seats, credits, model discount, and support against expected use before committing.

Platforms

SmythOS supports API, Linux, macOS, self-hosted, web, and Windows. Alongside web access, the range includes desktop operating systems and self-hosting options for teams that need to run agents within their own environments.

Who it's for

SmythOS is best suited to teams that need to build agents through visual tools or conversational prompts, connect services, and choose among hosted, local, on-premises, or VPC deployment. The integration and model options make it relevant to teams assembling workflows across existing services. It is less suitable for buyers who need one predictable price that covers model usage, or teams whose seat needs exceed a plan’s allowance without moving to a higher tier.

Pros and cons

• Pros: Visual Studio and Agent Weaver offer two ways to create and revise workflows, including a no-code canvas and conversational prompts.
• Pros: Deployment spans chat, APIs, webhooks, MCP servers, ChatGPT, local exports, and on-premises or VPC environments.
• Pros: Integrations, multiple model sources, and named vault integrations give teams choices when connecting services and managing secrets.
• Cons: Built-in model usage is charged separately, making the subscription price an incomplete view of operating cost.
• Cons: The lower paid tiers have limited daily API-call quotas, and Startup and Scaleup cap seats at three and five respectively.
• Cons: Free options have one seat, limiting their usefulness for collaborative team work.

Alternatives

For a general-purpose assistant rather than a platform centered on agent construction and deployment, Microsoft Copilot has a free plan with access subject to capacity and usage limits, and supports web, Windows, macOS, iOS, and Android.

QuickBlox Chat API is an alternative for teams seeking a chat API; its free Basic plan includes 500 total users, one month of data retention, a 10 MB file limit, and community support.

Wordware is another free-plan option, with web and iOS platforms and a Lite plan at $29 a month billed per month.

Bottr is another option with API and web platforms and a free tier.

Verdict

Choose SmythOS if your team needs agent-building tools plus flexibility over integrations, deployment, and hosting, especially when local, on-premises, or VPC deployment matters. Its main advantage is bringing those choices into one platform; its main drawback is that model charges sit outside most subscription costs and quotas and seat caps vary by tier. Look elsewhere if a simple, predictable total price matters more than deployment options.
