Durable, horizontally scalable messaging and event streaming platform that people reuse across many systems. Caveat: painful to operate and usually only worth it at large scale.

Why people recommend it
Each mark is one comment
Scales horizontally under heavy load
“From a performance POV, Kafka scales horizontally, and appends only need negligible locking.”
Comment from 21 Oct 2026 in “Revolut down as users report app not working” “Kafka already solves this problem and gives me message durability, near infinite scale out”
Comment from 8 Dec 2025 in “IBM to acquire Confluent” “made Twitter stable under the load of several hundred million users”
Comment from 18 Aug 2026 in “Ask HN: GitHub employees what's going on? Why?” Battle-tested with many known solutions
“a benefit of using well known software like Kafka is a lot of problems you will run into have solutions/guidance already available”
Comment from 19 Aug 2026 in “PostgreSQL for Everything” “We built TBMQ on Kafka because it's battle-tested at scale across the industry”
Comment from 3 Mar 2026 in “Show HN: TBMQ – Live demo of a high-performance MQTT broker built on Kafka” “OSS projects that scale well, say Linux, Postgres, Kafka, redis”
Comment from 29 Apr 2026 in “Ghostty is leaving GitHub” Useful features out of the box
“Kafka has that out of the box. Where kafka starts to come apart is how to set it up.”
Comment from 4 Dec 2025 in “Show HN: Walrus – a Kafka alternative written in Rust” “anything else a Kafka-like comes with out of the box”
Comment from 2 Jul 2026 in “Postgres transactions are a distributed systems superpower”
What people warn about
Each mark is one comment
Heavy to operate and resource-hungry
“It's very good at what it does, but painful to manage and usually not worth the pain for anyone who's not in a mega enterprise.”
Comment from 20 Mar 2026 in “Java Is Fast. Your Code Might Not Be” “Kafka I will grant you is a lot to operate, but I would not choose Kafka unless I have a Kafka-shaped problem”
Comment from 21 Aug 2026 in “PostgreSQL for Everything” “Kafka is... a lot. If you need what it provides, then it's great.”
Comment from 11 Apr 2026 in “Keeping a Postgres Queue Healthy” - Comment from 8 Dec 2025 in “IBM to acquire Confluent”
- Comment from 7 Dec 2025 in “The end of the road for Kafka-delta-ingest”
Confusing APIs and setup gotchas
“One of the secret traps of Kafka is that it tried to be a collection of nice primitives without that much built on top”
Comment from 3 Nov 2025 in “"You Don't Need Kafka, Just Use Postgres" Considered Harmful” “Kafka's apis are full of landmines and gotchas, and you can do much better from a UX perspective”
Comment from 26 Aug 2026 in “Show HN: PicoMQ – Durable Streams over HTTP, on object storage” “devs trip over Kafka topics, partitions and offsets when their throughput is low enough”
Comment from 8 Dec 2025 in “IBM to acquire Confluent” Buggy clients and poor performance
“Some poor quality software with bad performance, but an established piece of tech regardless.”
Comment from 16 Jan 2026 in “Show HN: Ayder – HTTP-native durable event log written in C (curl as client)” “Kafka clients for several languages are pretty much unusable due to bugs and/or performance”
Comment from 2 Sep 2026 in “Apache Iggy, a message streaming platform in Rust, graduates to an Apache TLP” Head-of-line blocking under concurrency
“Kafka for head of line (HoL) blocking under concurrent events can be an issue though”
Comment from 14 Dec 2025 in “How exchanges turn order books into distributed logs” “It's the very architecture of Kafka itself due to the notorious head of line problem”
Comment from 4 Dec 2025 in “Show HN: Walrus – a Kafka alternative written in Rust”

“From a performance POV, Kafka scales horizontally, and appends only need negligible locking.”
“a startup that uses Cloudflare for everything except for Kafka”
“you let Kafka hold onto new data until batch insertions can catch up”
“Kafka clients for several languages are pretty much unusable due to bugs and/or performance”
“Kafka's apis are full of landmines and gotchas, and you can do much better from a UX perspective”
“Kafka I will grant you is a lot to operate, but I would not choose Kafka unless I have a Kafka-shaped problem”
“a benefit of using well known software like Kafka is a lot of problems you will run into have solutions/guidance already available”
“made Twitter stable under the load of several hundred million users”
“The second biggest use is Apache Spark/Kafka, but with LLMs now, you can pretty much re implement all of that functionality in pure C.”
“systems like Kafka give you practical implementations”
“Kafka is actually distributed tech. You can lose nodes and keep operating.”
“anything else a Kafka-like comes with out of the box”
“they build world class software that backs massive systems like elastic search, Kafka”
“OSS projects that scale well, say Linux, Postgres, Kafka, redis”
“Kafka is... a lot. If you need what it provides, then it's great.”
“It's very good at what it does, but painful to manage and usually not worth the pain for anyone who's not in a mega enterprise.”
“We built TBMQ on Kafka because it's battle-tested at scale across the industry”
“it made the immutable approach easier than the spaghetti alternative”
“very fast to start up (~100ms) and use relatively little memory”
“a pretty fun high-level summary of the underlying idea behind them”
“doubling kafka provisioned capacity is simpler, easier, cheaper, and more reliable approach”
“it has caught up fairly well to these alternatives re: memory and startup time”
“Some poor quality software with bad performance, but an established piece of tech regardless.”
“Kafka is taking an interesting turn however with the KIP-932 "Queues for Kafka" initiative”
“An ecosystem building on Kafka clients libraries with various non-Kafka servers would work fine too, but we didn't figure out how to easily do that.”
“Kafka for head of line (HoL) blocking under concurrent events can be an issue though”
“A Kafka consumer does a lot of work coordinating distributed clients in a group, managing the current offset, balancing the readers across partitions”
“If you wanted something fully durable with a stronger persistence story you'd probably use Kafka anyhow.”
“Rewriting the code at that point may be less costly than operating Kafka in the interim.”
“Kafka already solves this problem and gives me message durability, near infinite scale out”
“devs trip over Kafka topics, partitions and offsets when their throughput is low enough”
“Kafka (the messaging/streaming platform) has finally found its natural home.”
“portfolio is starting to look interesting again, especially if it includes Kafka”
“Kafka is a very resource-heavy application that's worth replacing with leaner options”
“Kafka has that out of the box. Where kafka starts to come apart is how to set it up.”
“operational overhead is much lower than running a full Kafka stack”
“It's the very architecture of Kafka itself due to the notorious head of line problem”
“Scaling issues can develop and we in Ops catch flak for your bad design choices.”
“One of the secret traps of Kafka is that it tried to be a collection of nice primitives without that much built on top”
“Going through Kafka allows for reply and setting up multiple independent consumers for the same change event stream.”
