IoT CLOUD PLATFORM BUILT FOR DEVELOPERS

Connected Systems without the Anxiety.

Monitor and control fleets of devices with easy-to-integrate Device
SDKs, Type-Safe Schemas, and Programmable Actions.

Fostrom is completely free while in Technical Preview.

The Platform

Typed Payloads

Schemas

Validate every payload and keep devices safe from unexpected shapes.

Programmable Logic

Actions

Run JavaScript in response to messages, test in place, and
orchestrate real-world effects.

Deterministic Delivery

Mailboxes

Sequential device mail with predictable ordering.

Full Fleet Context

Observability

Inspect packet history, activity graphs, and fleet health in one
place.

Ship Fast

Device SDKs

Python, JavaScript, and Elixir SDKs with a tiny integration surface.

Connected Everywhere

Protocols

SDKs, HTTP, and MQTT for every device and gateway.

Global Regions for Low-Latency Fleets

Pick the closest region to keep connections low-latency and
power-efficient.

Schemas

Typed Schemas Keep Data Correct

Define schemas for datapoints and messages so payloads are validated
on ingress and egress.

  * Reject and log invalid payloads
  * Backwards-compatible schema changes
  * Fewer device-side surprises

Typed Schemas Keep Data Correct
Actions

Actions Turn Signals Into Decisions

Write JavaScript code that reacts to incoming messages and triggers
real-world effects.

  * Triggered on inbound messages
  * Send mail to other devices or call webhooks
  * Test actions before deploying

Actions Turn Signals Into Decisions
Mailboxes

Sequential Mailboxes Protect Devices

Each device processes mail in order, at its own pace, with built-in
back-pressure.

  * Predictable ordering semantics
  * Per-device mailbox visibility
  * Safer, simpler device code

Sequential Mailboxes Protect Devices
Observability

Observe Every Packet

Inspect packet history, device health, and action effects with full
fleet context.

  * Complete packet history
  * Filter by device and schema
  * Trace action outcomes

Observe Every Packet

Built for Real-World Connected Systems

Energy

Collect telemetry, automate with Actions, and export data to
analytics pipelines.

Agriculture

Coordinate systems like pumps, lights, and climate control in large
farms with ease.

Logistics

Stream sensor data reliably and trigger alerts the moment thresholds
are crossed.

Research

Monitor research experiments on a unified dashboard and get clean
data for analysis.
