SketchLog
Bounded-memory telemetry for observability
What this is
An open-source observability platform that stores compact telemetry summaries instead of every raw event, for engineering teams who want p95/p99 and anomaly tracking without ballooning storage costs.
Our one-line summary — not the founder’s tagline.
- How it works
- An open-source observability platform that uses sketch data structures to answer production questions — p95/p99 latency, unique users, top events, anomaly movement, SLO burn — from compact telemetry summaries instead of storing every raw event. Includes a hosted playground, dashboards, Postgres durability, SDKs, and Docker/Helm/Kubernetes support.
- What's different
- Keeps only compact statistical summaries rather than raw event storage, cutting storage costs.
- Best for
- Engineering teams who want latency and anomaly tracking without their storage bill ballooning.

No money. No seat. It goes on your record — and in 28 days reality settles it.

Analytics. Launched 9d ago on Product Hunt, picking up 16 votes. Today, it's been quiet for 9 days and the price has started to bleed.
Already bleeding a little every day, and it accelerates the longer it stays quiet.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 16 votes.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
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.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
