Hailo
Pros
- + Per-watt vision inference is the best I have measured in this class: ~85-90 fps on YOLOv8m 640x640 at 2.5W typical on a Pi 5, roughly dual-Coral throughput in one passive card
- + 4-8 GB on-module LPDDR4/4X removes the on-chip SRAM ceiling that limited the Hailo-8, so larger detectors and quantized small LLMs actually fit
- + Model Zoo ships 150+ vision models plus quantized LLM/Whisper support across TensorFlow, TFLite, Keras, PyTorch and ONNX
- + Wide host reach: M.2 Key M over PCIe Gen3 x4 on x86 and ARM, Linux/Windows/Android, industrial temperature range to 85C
- + Raspberry Pi AI HAT+ 2 at $130 is a genuinely cheap entry to 10H-class performance, backed by a 10,000-member builder community
Cons
- - Acquired by Microchip in July 2026 after a collapsed SPAC, emergency financing and ~50% layoffs — roadmap and supply continuity are provisional
- - Generative-AI marketing oversells reality: 'up to 10B parameters' means 4-bit paging at single-digit token rates; treat it as a vision accelerator
- - The dataflow compiler is its own dialect — unsupported ONNX operators silently fall back to CPU and eat throughput
- - No free tier or trial, no subscription model: you buy modules from distributors at street prices ($220-$280 bare, ~$130 as the Pi HAT)
- - Not a computer — every deployment needs a separate host, video decode and power budget (Pi 5 + HAT+ runs ~$195 all-in)
Langfuse
Pros
- + MIT-licensed core with free, unrestricted self-hosting — only named enterprise features like audit logs and SCIM need a licence key
- + A 5-seat team at 100k traces runs roughly $69/month versus about $420/month for the main closed alternative (Panoply's independent estimate, consistent with my bills)
- + OpenTelemetry-native tracing across OpenAI SDK, LangChain, LlamaIndex, Pydantic AI, Vercel AI SDK, CrewAI and raw OTLP
- + Graduated usage pricing is transparent and cheap: worked examples on the pricing page match my own invoices (200k units on Core = $37/month)
- + Dataset-backed evaluation with the langfuse/experiment-action GitHub step let me gate prompt changes in CI on a real test set
Cons
- - v3 self-hosting needs Postgres, ClickHouse, Redis and S3 where v2 ran on one container — a four-service system to operate
- - Heavy agent traces render slowly in the UI (issue threads #10391 and #9933 match the multi-second loads I measured)
- - Online evaluations score a sample of traffic rather than everything, so rare failure modes can go unscored
- - UI-configured evaluators cannot be triggered programmatically for scheduled pipelines in my setup
- - Owned by ClickHouse, Inc. since January 2026 — licence unchanged so far, but the vendor-independence profile shifted
