Introduction

Parseable is an open-source, columnar data lake platform built for observability. You send logs, metrics and traces through popular logging agents, OpenTelemetry, Kafka, eBPF or other integrations, then use native alerting, dashboards, anomaly detection, APM, PromQL and SQL, all within a single binary.

Its architecture separates stateless compute from object storage, which keeps costs down; it is written in Rust and uses open Parquet files and open standards. Columnar design helps with high-cardinality data. It can be deployed on public or private clouds or used as managed Parseable, and views include service maps, an error page, AI analysis and root-cause analysis.

For test and QA teams, cheap, long-retention logs make it easier to investigate flaky test environments and compare behaviour across releases.

The source code is at parseablehq/parseable on GitHub under the AGPL-3.0 licence, with about 2,600 stars; the most recent commit was on 11 November 2026.

Launch and background: Parseable was posted to Hacker News as a Show HN on 6 October 2026.

Features

  1. Data lake architecture: Stateless compute over object storage.
  2. Open Parquet: No proprietary storage format.
  3. Multiple ingest paths: OpenTelemetry, Kafka, eBPF and agents.
  4. SQL and PromQL: Familiar query languages.
  5. Alerts and anomaly detection: Built in.
  6. Single binary: Simple deployment.

Pros

  1. Low storage cost: Object storage based.
  2. Free to use: Open source under the AGPL-3.0 licence, so the core tool costs nothing to use.
  3. Actively maintained: The repository had commits as recent as 11 November 2026.

Cons

  1. AGPL-3.0: Copyleft licence.
  2. Younger ecosystem: Fewer integrations than incumbents.
curl -fsSL https://logg.ing/install | bash

Then send data via OpenTelemetry or the HTTP ingest API and query it with SQL.

Pricing

Parseable is free and open source under the AGPL-3.0 licence.

  1. Teams with high log volumes and tight budgets.

Conclusion

Parseable is a cost-efficient, open-format observability store.

Pilot it with one high-volume service.
