Logchef – Schema-agnostic log viewer for ClickHouse
Hey HN! I’m Karan, creator of Logchef (https://logchef.app), an open-source log viewer built specifically for exploring logs stored in ClickHouse. This tool grew directly out of my $day job managing massive log volumes. Like many orgs, we migrated our log workloads to ClickHouse for its performance, but found the ecosystem lacked dedicated UI tooling for actually browsing and analyzing those logs effectively. We were using Metabase, and while great for general BI, it wasn't designed for log exploration workflows. Common pain points included: - Clunky Ad-hoc Querying:…
Logchef – Schema-agnostic log viewer for ClickHouse launched on April 27, 2025 with 41 votes, #642 of 7,818 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Logchef is an open-source log viewer designed for exploring logs stored in ClickHouse. Built for teams managing large log volumes, it provides a dedicated interface for log browsing and analysis that general business intelligence tools like Metabase don't offer. The tool simplifies ad-hoc querying of ClickHouse data and enables seamless navigation between visualized trends and raw log entries, addressing common workflows in incident investigation and log exploration.

LogchefAug 2026 · logchef.app · ▲6Hey HN, I'm Karan. I built Logchef because we moved our log workloads to ClickHouse at Zerodha and found the ecosystem lacking for actual log exploration. Tools like Metabase and Grafana are great for dashboards, but log exploration is a different workflow. The Grafana ClickHouse plugin requires manual column configuration for logs, has no field sidebar, and its ad-hoc filters are slow on large tables. Grafana's RBAC is Enterprise-only, and even then it's datasource-level and not at table-level. If someone has access to the ClickHouse datasource, they can query any table. In Logchef, you…
SigNoz – open-source alternative to DataDog, NewRelic2022 · github.com · ▲510We just released a major upgrade to SigNoz with support for Logs management based on ClickHouse. Would love to get any feedback from the community here on what you think and any questions you may have for us Many big companies like Uber and Cloudflare have been shifting to ClickHouse as their main workhorse for Logs management seeing much better performance. for e.g Cloudflare recently shifted from Elastic to ClickHouse and are seeing 8x improvement in memory/cpu resource requirement in ingestion. This is our first release with Logs support and we have added support for: - Filtering…
Telescope – an open-source web-based log viewer for logs in ClickHouse2025 · github.com · ▲172Hey everyone! I’m working on Telescope - an open-source web-based log viewer designed to make working with logs stored in ClickHouse easier and more intuitive. I wasn’t happy with existing log viewers - most of them force a specific log format, are tied to ingestion pipelines, or are just a small part of a larger platform. Others didn’t display logs the way I wanted. So I decided to build my own lightweight, flexible log viewer - one that actually fits my needs. Check it out: Video demo: https://www.youtube.com/watch?v=5IItMOXwugY GitHub:…
We built a ClickHouse-based logging service2023 · github.com · ▲192Hey hn! I'm one of the co-founders of highlight.io, an open source monitoring tool. Today we're sharing a ClickHouse-based logging solution we've been working on. We wanted to showcase how we built it and share how you could try it out to give feedback. Since we started working on highlight.io, we've been hyper-focused on "cohesion", or ensuring that when you install your monitoring stack, all of the resources in that stack (user interactions, requests, traces, logs, etc.) are connected in a consumable way. We've written up more about our philosophy on this here [1]. We started building…
Open-source Kibana alternative for logs and traces in ClickHouse2024 · github.com · ▲125Hi HN, Mike and Warren here! We're excited to share some (early) work towards our next major version of HyperDX. HyperDX makes it easy to visualize/search logs & traces on top of Clickhouse (so incident & bug investigations hopefully go by a little easier). For example, if a team is thinking of migrating to Clickhouse for their observability data warehouse [1][2][3] usually due to cost or data privacy reasons, they can easily throw HyperDX on top to do the UI layer for analysis and dashboarding in a dev-friendly way (aka not needing to type paragraphs of SQL to find some logs) Over the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
