What is Better Auth?
For TypeScript developers, auth has long meant choosing between rolling your own (risky) or renting a closed service (lock-in). Better Auth offers a third way that's caught fire in the community — 'the most comprehensive authentication framework' for TypeScript, one that lives inside your own app rather than on someone else's servers.
Auth that lives in your codebase
Better Auth is a composable, plugin-based authentication framework that runs inside your application, giving you full control and no vendor lock-in. It provides built-in credential authentication with sessions, email verification and password reset out of the box — the essentials, implemented correctly so you don't reinvent them. Because it's a framework in your code rather than an external API, you own the whole flow and your users' data stays with you. It sits alongside self-hostable auth tools like SuperTokens, Logto and Ory.
35+ methods, from magic links to passkeys
Better Auth supports 35+ authentication methods, including social sign-on (Google, GitHub, Apple, Discord), passkeys, magic links and multi-factor authentication. That breadth means whatever login experience you want to offer, it's likely a plugin away rather than a custom build. The plugin architecture is key — you add exactly the capabilities you need and nothing you don't, keeping your auth lean and tailored.
Scales to enterprise
It's built to grow from a weekend project to enterprise scale. Multi-tenancy — teams, roles, invitations and access control — is built directly into the framework, and enterprise features include SSO, SAML 2.0, SCIM and directory sync, plus real-time security detection for bots, brute-force attempts and suspicious access. That means you won't outgrow it when you land your first big customer.
Framework-friendly
Better Auth works with Next.js, Nuxt, SvelteKit, Astro, Hono and 20+ more frameworks, so it fits the modern TypeScript ecosystem naturally rather than fighting it.
Who it's for
Better Auth suits developers building TypeScript applications who want flexible, self-hosted authentication without vendor lock-in — from solo hackers to enterprise teams.
Pricing
Better Auth is freemium: the open-source framework is free and self-hosted, with optional paid infrastructure services (a dashboard, audit logs, security detection and enterprise features) available on paid plans. You can build entirely on the free open-source core and add managed services only if you want them.
Bottom line: Better Auth is a comprehensive, plugin-based auth framework that lives in your TypeScript app — 35+ methods, multi-tenancy and enterprise SSO, fully self-hosted with no lock-in — which is exactly why it's become a developer favorite.
What is LanceDB?
Training and running modern AI models isn't just about the model — it's about wrangling enormous amounts of data, from raw files to production-ready features, without your infrastructure buckling. LanceDB tackles that whole problem as 'the AI-native multimodal lakehouse,' unifying data management and vector search for AI teams.
From raw files to features, in one place
LanceDB is designed to accelerate AI model development by managing training data end to end. It enables fast data curation through search and deduplication, scalable feature engineering with Python UDFs and automatic updates, and accelerated training (with up to 70% Model FLOPS Utilization). Rather than stitching together separate systems for storage, search and feature prep, ML teams get a unified platform — which dramatically shortens the iteration cycles that dominate real AI work.
Search across everything
LanceDB supports vector/semantic, full-text and hybrid search combined with SQL filters, so you can query your data however the task demands. It sits alongside dedicated vector databases like Weaviate, Qdrant and Chroma, but with a distinctive focus on the multimodal data lakehouse — managing text, images and video together at the scale training large models requires.
Built for scale and experimentation
Under the hood, LanceDB is built on the open-source Lance columnar format and scales to handle 100+ billion rows and 100K+ queries per second. Crucially for ML workflows, it lets you version datasets, branch for experiments, and evolve schemas without rewriting data — so you can iterate on training data as freely as you iterate on code. That versioning-and-branching model is a genuinely powerful fit for how AI research actually happens.
Made for multimodal AI
As AI increasingly works across text, images and video, having infrastructure built from the ground up for multimodal data — rather than retrofitted from a text-only vector store — is a real advantage for teams pushing the frontier.
Who it's for
LanceDB suits ML teams and AI companies building and training large-scale models, especially those working with multimodal data who need efficient data management and rapid iteration.
Pricing
LanceDB offers a free, open-source core plus managed LanceDB Cloud and LanceDB Enterprise offerings for teams that want it fully handled. You can start free and self-hosted on the open-source Lance format, then move to managed as you scale.
Bottom line: LanceDB is an AI-native multimodal lakehouse that unifies training-data management with vector, full-text and hybrid search — scaling to 100+ billion rows with dataset versioning and branching, purpose-built for teams training serious multimodal models.
