You can use it for free with no login here to explore the data interactively yourself. --------------------------------------------------------------------- 18 years * 1.8 million headlines * 13 database engines Hacker News is a real-time barometer of developer excitement. I mined every story title from February 2007 to June 2025 and asked three questions: * How has headline volume for each database changed over time? * Which engines are accelerating the fastest right now? * Which ones are losing steam? 1 * Raw popularity through time The chart below shows monthly headline counts for the eight most-talked-about engines, plus DuckDB (small base, big growth). Click on the individual database names to toggle their visibility. Double click to isolate a single database. PostgreSQL's curve is a near-monotonic climb; by 2020 it dwarfs every other line. MySQL dominates the pre-2012 era, then flat-lines. MongoDB peaks around 2013, then slips as SQL engines add JSON support. ClickHouse (2016) and DuckDB (2020) rocket up in the analytics renaissance. Redis & SQLite are steady, underscoring their "invisible infrastructure" roles. 2 * Who's gaining the fastest? I compared the last 12 months (Jul 2024 - Jun 2025) with the previous 12 months, then fit a linear regression over the last 36 months to capture trajectory. Engine Headlines 2023-24 YoY D 3-yr slope (mentions / 2024-25 % mo) DuckDB 225 149 +50.7 +0.44 % ClickHouse 211 170 +24.1 +0.39 % Supabase 105 84 +25.0 +0.12 % PostgreSQL 1 229 1 315 -6.6 % +1.22 Snowflake 106 156 -32.1 +0.01 % Redis 180 236 -23.7 +0.07 % MySQL 164 185 -11.4 +0.03 % MongoDB 96 78 +23.1 +0.03 % SQLite 436 407 +7.1 % +0.04 DynamoDB 25 38 -34.2 -0.08 % BigQuery 20 35 -42.9 -0.05 % Redshift 10 18 -44.4 -0.05 % TimescaleDB 3 4 -25.0 -0.01 % DuckDB tops the growth chart: half of its lifetime headlines appeared this year. ClickHouse maintains double-digit gains on a larger base, buoyed by vector search & managed services. Supabase benefits from the "Firebase, but OSS" narrative. PostgreSQL's YoY dip merely reflects an all-time-high 2023; its 3-yr slope (+1.22) is the steepest of all. Cloud-native SaaS engines (DynamoDB, BigQuery, Redshift) are down sharply in share of conversation. 3 * Engines in decline Headline counts aren't everything, but they do reveal mind-share: Engine Peak year Peak headlines 2024-25 headlines % off peak MongoDB 2013 242 96 -60 % MySQL 2009 267 164 -39 % DynamoDB 2019 59 25 -58 % BigQuery 2020 62 20 -68 % Redshift 2016 61 10 -84 % Why? Maturity - less novelty, fewer "Show HN" launches. OSS competition - Postgres extensions + parquet/iceberg lakehouses replace single-purpose stores. Discussion shift - Cost, lock-in, and serverless topics often omit the product name. 4 * Engagement-Weighted View of Hacker News Database Stories (July 2024 - June 2025) Beyond raw headline counts, weighting stories by Hacker News points and comments reveals how intensely developers engage with each database. Database Stories Total Total Avg Points per Avg Comments Points Comments Story per Story PostgreSQL 1,229 26,185 8,666 21.3 7.1 SQLite 436 17,598 5,136 40.4 11.8 Redis 180 5,995 2,392 33.3 13.3 DuckDB 225 5,001 1,140 22.2 5.1 ClickHouse 211 3,147 891 14.9 4.2 Snowflake 106 1,212 518 11.4 4.9 MySQL 164 1,167 514 7.1 3.1 Supabase 105 849 548 8.1 5.2 MongoDB 96 572 362 6.0 3.8 BigQuery 20 342 142 17.1 7.1 DynamoDB 25 183 85 7.3 3.4 Redshift 10 37 1 3.7 0.1 TimescaleDB 3 3 1 1.0 0.3 Aggregate story count, points, and comments for each database in the last 12 months. Insights when weighting by points: * PostgreSQL dominates raw engagement--no surprise given its sheer volume of stories. * SQLite punches far above its weight: * Only one-third the story count of Postgres but two-thirds the total points. * Highest average score per story (40 pts) among mainstream engines. * Redis consistently sparks high-interest conversations, ranking highly in average points per story. Insights when weighting by comments: * High-comment threads often involve operational war stories or novel deployments (e.g., "SQLite in production at the edge"). * BigQuery and DynamoDB receive respectable per-story points (17 and 7, respectively) yet generate fewer comments, hinting at passive interest rather than debate. * TimescaleDB and Redshift barely move the needle, confirming their sliding community mind-share. What the weighted lens adds: Raw mention counts reveal frequency; weighting by points and comments captures intensity of community reaction. * SQLite's high per-story engagement reinforces its status as a beloved workhorse. * DuckDB garners solid points but fewer comments, typical for emerging tools still new to many readers. * ClickHouse stories show moderate engagement, suggesting interest but perhaps less day-to-day usage among the broader HN audience. Taken together, frequency and engagement metrics offer a richer, more nuanced perspective on developer sentiment. Takeaways Both raw popularity and weighted engagement metrics show clear trends: * Open-source engines drive most new discussion. * Analytics-focused stores (DuckDB, ClickHouse) gain as work moves from batch to interactive. * Slow, steady improvement (PostgreSQL) beats hype cycles. * Proprietary cloud databases draw fewer submissions over time. Further analysis Questions you can run next: * Which databases appear most in headlines containing "alternative to" or "replacing"? * What's the ratio of positive (launched, shipped) vs negative (outage, breach) headlines? * How do vector database mentions (Pinecone, Weaviate, Qdrant) compare to traditional databases? * Which lesser-known databases are on exponential growth curves?
