SQLite for Everything | JoeCode JoeCode<br>SQLite for Everything<br>Aug 19, 2026<br>Dr. Raphael Bauer penned an excellent article (PostgreSQL for Everything) on the value of using PostgreSQL to power your enterprise. I’ve taken the liberty of correcting a couple of errors, mainly he should of chosen SQLite 😊 (this is mostly a joke, I ❤️ PostgreSQL, its great tech.)<br>Contrary to popular belief, the answer to everything is NOT 42. It’s SQLite. (Fine. It might also be sqlite3.)<br>Table Of Contents<br>IntroRock Solid and StableEasy to Run, Install and ScaleSimplifies Your IT SetupSQLite Replaces Solr and Elastic: Full-Text SearchSQLite Replaces MongoDB: Excellent JSON SupportSQLite Replaces Kafka and RabbitMQ: SQLite as a QueueSQLite Replaces Clickhouse: High Volume Time Series DataSQLite as Vector Database for AI WorkflowsSQLite Replaces Redis: Non-Persistent High Performance CachingSQLite Replaces the File System: For Raw DataSQLite Replacing Your Graph DatabaseSQLite Replacing Your MicroserviceSQLite Replacing Your PlayStation 5ConclusionIntro<br>SQLite will outlive most of what you are running right now.<br>Back then the accepted wisdom was that SQLite was a toy. A file. Something you shipped inside a phone app so you didn’t have to write a config parser. Real applications got a real database with a real port number and a real daemon and a real 3am page.<br>In my humble opinion, the power of SQLite comes from three sources:<br>It is rock-solid and stable.It is easy to run, install and scale. Mostly because there is nothing to run.It massively simplifies your IT setup by being not only an RDBMS, but also a full-text search engine, a document store, a cache, a vector index, and a file format.Let’s have a closer look.<br>Rock Solid and Stable<br>SQLite is boring old technology. First release: 2000. It is also, by a margin that isn’t close, the most widely deployed database engine on the planet. It’s in your phone. It’s in your browser. It’s in your car. It’s in the plane you flew here on. There are more running copies of SQLite than there are running copies of everything else combined, and it isn’t a contest.<br>Ironing out bugs in database systems takes time. SQLite had that time, and then kept going. The test suite has 100% branch coverage under MC/DC, the same standard used for avionics software. There is roughly 500 times more test code than library code. The project has a stated support commitment through the year 2050, which is a longer planning horizon than your company’s mission statement.<br>It’s also in the public domain. Not open source. Public domain. No license, no CLA, no attribution clause, no vendor with a Series C and a change of heart.<br>True, SQLite is old. But it keeps quietly shipping modern features: window functions, RETURNING, strict tables, generated columns, jsonb. Every release is a small, well-tested, backwards-compatible improvement, which is the least exciting and most valuable thing a database can be.<br>Easy to Run, Install and Scale<br>Installing SQLite locally is easy in the sense that you have already done it. It is bundled with every major Linux distribution, ships inside Python, Ruby, PHP, Go, Rust, .NET, Android and iOS, and is sitting on your Mac right now whether you asked for it or not.<br>Running tests against a database identical to production is not a Test containers problem here. It is :memory:. Your test suite spins up a fresh database in microseconds, per test, in parallel, with no Docker daemon and no port collisions. The thing you test against is the thing you ship, because it’s the same library compiled into the same binary.<br>If you want to run SQLite on a server: you already are. It came with the OS.<br>Scaling is the part where people expect the article to get quiet, so let’s not:<br>Vertical: a modern NVMe drive and a machine with 128GB of RAM will serve a shocking amount of traffic when your database round trip is a function call instead of a network hop. No connection pool. No TLS handshake. No pgbouncer. Nanoseconds instead of milliseconds.Replication and backup: Litestream streams your WAL to S3 continuously. LiteFS gives you distributed reads. Both are small, single-binary, and boring.Hosted: Turso, Cloudflare D1, rqlite, and friends will happily sell you SQLite with a control panel if you miss having a control panel.That makes SQLite one of the most widely supported pieces of software in existence. For you this means less maintenance and more time building features for clients.<br>Simplifies Your IT Setup<br>Running SQLite in the cloud is zero clicks, because it’s a file next to your application. But it gets better. SQLite can replace a whole shelf of systems you’d otherwise be running.<br>SQLite Replaces Solr and Elastic: Full-Text Search<br>SQLite ships with FTS5, a full-text search engine built into the library you already have linked. Tokenizers, prefix queries, phrase queries, NEAR, boolean operators, custom ranking with BM25, and snippet/highlight functions for rendering results.<br>Two things worth appreciating...
