ObsessionDB – We rebuilt ClickHouse infrastructure to cut our costs 50%
Hey HN, I'm Marc. I run Numia, a blockchain data company serving real-time APIs at near-petabyte scale. ObsessionDB is managed ClickHouse we built for ourselves that costs roughly 50% less than other managed options. Now we're launching it as a standalone service. We had the classic split: ClickHouse for real-time analytics APIs, BigQuery for data warehouse workloads. Data replicated between both, costs adding up. Managed ClickHouse worked but was too expensive to put our warehouse workload into. Self-hosted meant replica nodes doubling storage and waiting days to copy 25TB to new replicas.…
ObsessionDB – We rebuilt ClickHouse infrastructure to cut our costs 50% launched on January 23, 2026 with 12 votes, #893 of 14,584 launches that month and more than 90% of that year's launches.
In plain words
ObsessionDB is a managed ClickHouse service that separates storage and compute to reduce infrastructure costs by approximately 50% compared to other managed options. Built by Numia, a blockchain data company, it consolidates real-time analytics APIs and data warehouse workloads into a single system, eliminating the need to replicate data across multiple platforms. The service is designed for companies operating at large scales who want lower costs without the operational burden of self-hosting ClickHouse.

Fully managed hosting for ClickHouse software with obsessive performance per dollar. Drop-in replacement, zero operational overhead.
Managed ClickHouse® with always-hot data and ridiculous value for money. Built for companies serving real-time data at scale. On other managed ClickHouse® solutions, costs balloon as data grows. Same bad trade: pay much more, just to keep query times where they were a year ago. Measured on real customer workloads. As data volume grows along a log scale, ObsessionDB's p99 stays flat while $/query falls — competitors degrade on both. Reads loop between client and nodes. They never leave the cache. Your data is safe in object storage — but it is not in the query path. Unlike setups where every query dips down to S3 and back up again. Agentic workloads don't query like humans — they probe…from obsessiondb.com

ScratchDB – Open-Source Snowflake on ClickHouse2023 · github.com · ▲261Hello! For the past year I’ve been working on a fully-managed data warehouse built on Clickhouse. I built this because I was frustrated with how much work was required to run an OLAP database in prod: re-writing my app to do batch inserts, managing clusters and needing to look up special CREATE TABLE syntax every time I made a change. I found pricing for other warehouses confusing (what is a “credit” exactly?) and worried about getting capacity-planning wrong. I was previously building accounting software for firms with millions of transactions. I desperately needed to move from Postgres to…
ClickHouse-local – a small tool for serverless data analytics2023 · clickhouse.com · ▲289Me with my friend Vitaly Ludvichenko made an experiment to combine ClickHouse server and client to make a self-contained program running a database engine and processing data without a server: https://github.com/ClickHouse/ClickHouse/pull/150 Development continued in the past 6 years, and now clickhouse-local becomes a swiss-army knife for data processing. Say "ffmpeg" for datasets and more. It can resemble textql, octosql, dsq, duckdb, trdsql, q, datafusion-cli, spyql, but has better capabilities and performance. Here is a tutorial:…
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…
WaveHouse – Supabase for ClickHouseAug 2026 · wavehouse.dev · ▲20While building an IoT telemetry solution, we ran into hurdles with Clickhouse. For one, you can't insert quickly AND durably into Clickhouse without setting up something like Kafka, which gets complicated for quick projects wanting to make use of Clickhouse's powerful features. Then, trying to actually query Clickhouse and show data in a UI required a whole backend API to handle auth and permissions. We figured that all these parts together – fast, durable ingest, row-level and column-level security and roles, and realtime streaming – were a lot of scaffolding to have to rebuild for every…

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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
