About Singuli
Singuli is a platform that lets developers and business users create, test, and deploy AI agents without deep technical expertise. It combines a visual drag-and-drop builder with an API-first approach, enabling rapid prototyping and production deployment. The platform includes pre-built templates for common use cases like customer support and data extraction, a sandbox environment for safe testing, and real-time performance monitoring. It supports multi-step workflow automation, version control for agent configurations, and built-in error handling. Singuli integrates with Slack, Google Sheets, Salesforce, Zapier, REST APIs, and webhooks. The company recently open-sourced Persona.js, a vanilla-JS library for building agent UIs with native WebMCP support under an MIT license, expanding its ecosystem for developers who want custom frontends. Compared to other agent builders, Singuli offers a stronger bridge between no-code simplicity and developer control, but its pricing details are not transparently published, which may frustrate buyers needing upfront cost estimates.
Behind the Verdict
Singuli fills a specific niche: teams that want to move fast with AI agents without writing everything from scratch, but also need the option to dive into code when the visual builder isn't enough. We'd reach for this when building internal assistants for customer support or data retrieval, especially if we want to test different configurations in the sandbox before going live. The pre-built templates save time, and the API access means we're not locked into a no-code-only world. Where it bites: the lack of transparent pricing. Singuli uses usage-based plans with a free tier, but you won't find a public price list. That makes it hard to compare with tools like LangChain or Zapier's AI features, which have clear tiers. For enterprises with strict compliance needs, the absence of on-premise deployment is a dealbreaker. The open-sourcing of Persona.js is a welcome move — it shows the company is building for developer extensibility. But if you need hundreds of pre-built integrations, Singuli's list is still slim. Real-world usage suggests it works best as a rapid prototyping platform, but scaling to high throughput may require custom arrangements. Teams that prioritize cost predictability should look elsewhere or request a custom quote upfront.
