SketchLog is an open-source observability platform for compact telemetry summaries. It uses sketch data structures to answer production questions like p95/p99 latency, unique users, top events, anomaly movement, SLO burn, and streaming SQL without storing every raw event forever. It includes a hosted playground, dashboards, PostgreSQL durability, optional OmniKV embedded storage, SDKs, WebAssembly, Docker, Helm, Kubernetes docs, and proof-first CI/release checks.
Hi Product Hunt,
I’m Bala, the founder of SketchLog.
I built SketchLog because modern systems generate more telemetry than teams can afford to store forever as raw events. But many production questions do not require every raw event. Teams often need fast answers like p99 latency, unique users, top events, anomaly movement, SLO burn, or release impact.
SketchLog uses bounded-memory sketch data structures such as DDSketch, HyperLogLog-style cardinality, and Count-Min-style frequency tracking to keep compact, mergeable telemetry summaries.
It is not meant to replace Prometheus, Grafana, Loki, Datadog, New Relic, TimescaleDB, or data warehouses. It is designed to work beside them.
This launch includes a hosted playground, dashboards, Streaming SQL examples, PostgreSQL-backed durability, optional OmniKV embedded storage, SDKs, WebAssembly, Docker, Helm, Kubernetes docs, and proof scripts for storage and telemetry load behavior.
I would love feedback from observability engineers, SREs, platform engineers, database people, and open-source builders.
What would you want to see before trusting a bounded-memory telemetry system in production?
SketchLog caught my eye today. Wishing the whole team an amazing launch! 🎉🚀
sandbox p99 queries returned in like a second, even when i was throwing 10M events at it. the fact that i can drop in OmniKV instead of wiring up postgres locally is a really nice touch.
Loaded up the playground and ran a streaming SQL query against some sample telemetry, the response time felt surprisingly snappy for sketch-based storage. Curious how it holds up once I point our own SDKs at it on a real workload.
A hosted tier with a free usage cap beyond the playground would be a nice way to actually try SketchLog on real traffic before committing to self hosting. Right now jumping from the demo straight to Kubernetes feels like a big leap.
One thing I'd love to see is a built-in cost estimator that shows how much storage and compute each sketch configuration would consume before you deploy it, especially since the whole pitch is about not storing every raw event.

Who hunted SketchLog?
SketchLog was hunted by Bala Vignesh. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
