PicoMQ

81 HackerNews comments were scraped, but they cover two different products. The +71 threads concern PicoMQ proper: a Kafka-like event-streaming/message-queue engine backed by S3 object storage. Reception is curious and largely positive: praise for the documentation ('documentation is very clear'), the landing page, and the design choice of building a purpose-built S3Stream engine on AutoMQ core primitives rather than extending SlateDB (unlike S2-Lite, which is single-node only). Recurring user skepticism targets write performance, since regular S3 has 100-150ms write latency; the developer responds with a shared WAL across streams, server-side batching, client-side buffering, and optionally S3 Express One Zone (<10ms). Open benchmarks with AWS cost attribution were promised but not yet posted at comment time. Use cases floated include Discord-like chat (ordering preserved per stream), HN mirrors, and granular per-user/session/vehicle streams instead of Kafka's table-like topics. Pricing is claimed 'dirt cheap' (~1M messages/day at 200B each, roughly 6GB), though one reader notes reader bandwidth could be 10-100x message volume, favoring a caching layer. The +68 threads actually discuss PicoMEM, a Raspberry Pi Pico/RP2040 ISA card for retro PCs (WiFi code from yyzkevin's PCMCIA project, PSRAM code from PicoGUS), a different product caught by the same keyword.
