There are no proprietary on-device formats. ### Modern Developer Experience Use the quickstart CLI to create a working workspace tailored to your board. You can validate Spotflow on your hardware without first taking a sales call. ### More Powerful Metrics Add dynamic labels to metrics, such as stack usage per thread, and choose the collection interval for each metric. This provides precise observability while optimizing bandwidth and resource usage. ### Transparent, Predictable Pricing Pricing scales with your fleet. Every plan includes the full platform, without feature gates or per-device data caps. ### Independent and Silicon-Agnostic Spotflow is independent and silicon-agnostic, so your hardware decisions remain yours. ### Built for AI-Native Device Operations Logs, metrics, and core dumps are the foundation. Spotflow is building toward automated troubleshooting and issue fixing. ## Plan Comparison | Fleet | Spotflow | Memfault | | ------------- | ---------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------- | | 100 devices | Pro: EUR 249/month; unlimited architectures; 50 GB/month ingest; 45-day retention; unlimited custom metrics | Growth: EUR 3,495/month; two chips and one architecture; 1.2 GB/month ingest; 30-day retention; 20 custom metrics | | 500 devices | Pro: EUR 249/month; unlimited architectures; 50 GB/month ingest; 45-day retention; unlimited custom metrics | Growth: EUR 3,495/month; two chips and one architecture; 6 GB/month ingest; 30-day retention; 20 custom metrics | | 1,000 devices | Pro: EUR 499/month; unlimited architectures; 50 GB/month ingest; 45-day retention; unlimited custom metrics | Growth: EUR 3,495/month; two chips and one architecture; 12 GB/month ingest; 30-day retention; 20 custom metrics | | 5,000 devices | Scale: EUR 899/month; unlimited architectures; 2,000 GB/month ingest; 90-day retention; unlimited custom metrics | Enterprise: quote required; 60 GB/month ingest; 60-day retention; 60 custom metrics | ## Feature Comparison | Feature | Spotflow | Memfault | | -------------------- | ------------------------------------------------------------------------------- | -------------------------------------------- | | Supported platforms | Zephyr and ESP-IDF natively; others through MQTT | MCU, Android, Linux, and HTTP API | | Log querying | Rich operators | Rich operators | | Crash analysis | Stack traces, registers, variables, AI root-cause analysis, and fix suggestions | Stack traces, registers, variables, and heap | | Alerting | Included | Included | | OTA firmware updates | Included | Paid add-on | | Custom dashboards | Included | Included | | Free tier | Yes | No | | Self-service | Yes | Requires a call | ## Frequently Asked Questions ### How much does Memfault cost? Memfault's Growth plan starts at about USD 3,495/month for 1,000 devices, with custom enterprise pricing above that. There is no free tier. ### Can I migrate from Memfault to Spotflow? Yes. Spotflow uses standard MQTT transport and similar event semantics. Contact Spotflow to map your existing setup. ### Is Spotflow mature enough for production fleets? Spotflow is an early-stage company, but its architecture and engineering team come from Datamole, where the same people ran an industrial IoT platform with more than 100,000 production devices for customers including Lely and Agrifac. Spotflow runs on production fleets today with defined uptime and delivery commitments. ### Does Spotflow work with Zephyr and ESP-IDF? Yes. Spotflow integrates natively with Zephyr's logging and core-dump subsystems and provides first-class ESP-IDF support. Other operating systems can send data over MQTT. ### Is there a free tier? Yes. Spotflow is free for up to 10 devices, and no credit card is required.
