10 Best Seam Alternatives & Competitors (2026)

IFTTT focuses on simple, consumer-oriented automations across apps and devices with an easy applet system. While it lacks Zapier's enterprise AI agents and 9,000+ business integrations, it remains popular for personal productivity and basic notifications at no or very low cost.

Particle provides a device-to-cloud IoT platform with cellular and Wi-Fi modules plus a unified API. It excels at custom hardware fleets but offers fewer pre-built access-control components than Seam. Pricing is usage-based, which can become expensive for high-volume operations common in hospitality. Teams already using Particle hardware may prefer it, while those needing quick lock and thermostat integrations often choose Seam for faster time-to-market.

Losant is a visual workflow builder and API layer for industrial IoT. It supports many device types through MQTT and REST but lacks Seam’s ready-made access-code UI components. Losant’s strength is complex event processing; its weakness for SaaS teams is the extra front-end work required to deliver guest PINs or climate presets. Pricing scales with messages and dashboards.

Kisi focuses exclusively on cloud access control with native integrations for popular locks. It provides a clean API and mobile credentials but does not extend to thermostats or sensors. Companies needing only door management may find Kisi simpler, while those requiring unified climate and occupancy automation usually select Seam for broader device coverage.

IFTTT offers simple applets that connect consumer devices. It is free for basic use but lacks enterprise access controls, audit logs, and the granular API needed for commercial property management. Teams outgrowing IFTTT for professional use cases often migrate to Seam for production-grade reliability and multi-property dashboards.

SmartThings provides a consumer hub and developer API for Samsung and partner devices. Its strength is broad consumer device support; its limitation is weaker multi-tenant access management and enterprise SLAs. Property-tech companies needing staff credentials and usage analytics typically prefer Seam’s purpose-built commercial features.

Brivo is an established access-control platform with strong compliance features for commercial real estate. It offers APIs but focuses on doors rather than climate or sensors. Organizations that only need electronic locks may stay with Brivo, while those seeking a single API across locks, thermostats, and occupancy sensors choose Seam.

Home Assistant is an open-source local hub supporting thousands of devices. It requires self-hosting and custom development to expose a clean multi-tenant API. Companies unwilling to manage infrastructure or build guest-facing UIs often adopt Seam for managed hosting and pre-built components instead.

Salto KS delivers cloud-based electronic lock management aimed at multi-family and hotels. It provides solid access features but does not unify thermostats or sensors under one API. Property managers wanting climate automation alongside doors frequently select Seam for wider device orchestration.
