LanceDBFuse.jsMiniSearch
Quick read
- Free with no card: Fuse.js, MiniSearch.
| Field | LanceDBlancedb.com | Fuse.jsfusejs.io | MiniSearchgithub.com |
|---|---|---|---|
| What it is | An embedded vector database built on the Lance columnar format — no server process, data sits as files on local disk or in S3. Does vector similarity, full-text search and SQL filtering over the same table, and stores raw bytes, images and video alongside embeddings. Python, TypeScript and Rust SDKs. | A zero-dependency fuzzy-search library using the Bitap algorithm — roughly 6.8kB gzipped for the basic build, 8.6kB for the full one. Searches arrays of JS objects in memory with typo tolerance, field weighting, nested keys and extended query operators. Runs in browsers, Node and Deno. | A dependency-free JavaScript full-text search engine that builds a real inverted index in memory, in the browser or in Node. Supports prefix search, fuzzy matching, field boosting, modern relevance ranking, auto-suggestion, and adding or removing documents at any time. The index serializes to JSON so it can be prebuilt. |

| Cost tier | mixed | free | free |
| Pricing | OSS free (Apache 2.0), embedded, no server. LanceDB Cloud is usage-based across writes, queries and storage with $100 in free credits on the first month. Enterprise is custom. | Free, Apache-2.0. No service, no account, no limits, no bill. | Free, MIT-licensed. No service or account. |
| Why builders pick it | Think SQLite for vectors: pip install lancedb, point it at a directory, done. Zero-copy automatic versioning lets you time-travel an index, and the same code scales to the cloud tier. | When a few hundred to a few thousand items already sit in your app state — a command palette, a settings list, a filterable table — this is ten lines of code and no infrastructure. | The step up from Fuse.js when you have tens of thousands of records — a proper index instead of rescoring every item per keystroke, still with no backend and no bill. |
| Watch out for | Embedded mode has no multi-writer coordination — one writer at a time, or move to the managed tier. Cloud per-unit rates are behind a calculator rather than published. | It scores every item on every keystroke, so it degrades noticeably past roughly 10K records. Use MiniSearch or a real index above that. | The whole index ships to the client, so a large corpus means a large download. Prebuild and cache the serialized JSON rather than indexing on every page load. |
| How to wire it up | pip install lancedb | npm i fuse.js | npm i minisearch |

Prefer the free tier when no budget was stated, and say what the ceiling is. 2. Read the full dossier before integrating. 3. Fetch /api/public/models before writing any AI model ID.
