Project mention: We Cut Log Costs by 35% Using Vector 0.30 and Loki 3.0: Lessons from a 3-Month Tuning | dev.to | 2026-05-04
We evaluated three alternatives: ClickHouse for log storage, Fluent Bit for log collection, and the Vector (https://github.com/vectordotdev/vector) + Loki (https://github.com/grafana/loki) stack. ClickHouse had great query performance but required manual index management, which would add operational overhead. Fluent Bit was lightweight but lacked the transform capabilities we needed to mask PII and drop low-value logs. Vector and Loki stood out: Vector is a Rust-based agent with 1/10th the memory footprint of Filebeat, and Loki is designed for cost-efficient log storage with a query model that aligns with how our team actually debugs (using labels, not full-text search).

Some time ago I adopted Quickwit at my company. For anyone who hasn't used it: Quickwit is a search engine that runs full-text search directly on object storage (S3 or anything S3-compatible). It decouples compute from storage, so you don't pay to keep big indexes warm to search older data. That model fits logs well.

greptimedb
The open-source observability database. One columnar engine for metrics, logs, and traces, on object storage.
We also started with the typical kube-prometheus-stack, but we don’t like Prometheus/PromQL. Moreover, it only solves the „metrics“ part - to handle logs and traces, more quite heavy and complex components have to be added to the observability stack.
This didn‘t feel right, so we looked around and found greptimedb https://github.com/GreptimeTeam/greptimedb, which simplifies the whole stack. It‘s designed to handle metrics, logs, and traces. We collect metrics and logs via OpenTelemetry, and visualize them with Grafana. It provides endpoints for Postgres, MySQL, PromQL; we‘re happy to be able to build dashboards using SQL as that’s where we have the most knowledge.
The benchmarks look promising, but our k8s clusters aren’t huge anyway. As a platform engineer, we appreciate the simplicity of our observability stack.
Any other happy greptimedb users around here? Together with OTel, we think we can handle all future obs needs.

mirrord
Run any process, on your machine or in an AI agent's environment, as if it were a pod in your Kubernetes cluster: real env vars, DNS, network, traffic.
Project mention: How Prathyusha Ramanjaneyulu at Celonis Eliminated Dev Environment Overhead for 600 Engineers | dev.to | 2026-07-01As the owner of the Local Development component, Prathyusha is tasked with maintaining high engineering velocity for 600 developers. She mentioned her team maintains a proactive watch over the cloud-native ecosystem; it was through this strategic evaluation that she and her team identified both Telepresence and mirrord as potential solutions to address their bottlenecks.

fluvio
🦀 event stream processing for developers to collect and transform data in motion to power responsive data intensive applications.

-
AppSignal
AppSignal knows why the f*#k it crashed. Stop vibe-debugging. Every exception, every backtrace, grouped so you see patterns, not noise.
-
parseable
Parseable is an open source, unified infrastructure observability platform built in Rust on a data lake architecture. It tracks logs, metrics, traces, and events across apps, agents, and systems, reducing storage costs by up to 90% through columnar telemetry compression.
We migrated to Parseable, self-hosted on Kubernetes with Minio for S3-compatible storage, all running on bare-metal. The product still feels early, but the team is responsive and ships fixes fast when something breaks. Big shoutout to Anant and Deba!
