Welcome to Ollamadex, a clean, localized index and management engine designed to tame the expanding ecosystem of local AI. Instead of jumping back and forth to a browser to find the right tool for the job, Ollamadex acts as a private directory that automatically organizes available models, their parameter sizes, capabilities, and specific variants into a single, lightning-fast database on your machine. Built to be entirely self-contained and private, it gives you a deeply queryable inventory of the local AI landscape, making it perfect for powering custom application pickers, automating model workflows, or simply keeping track of the best weights available for your hardware.

Features

• Local-first model index - scrapes and stores Ollama's model library (names, descriptions, capability tags, size tags, cloud availability, and per-variant details like context length and disk size) into a single SQLite database on your machine.
• Fuzzy search caching - incoming search queries are compared against previously cached queries using Jaro-Winkler string similarity. A close-enough match (≥0.85 similarity) reuses the cached results instead of re-scraping, cutting down on redundant network calls.
• On-demand scraping fallback - if a query has no cached match (or a specific model isn't found by href), Ollamadex scrapes ollama.com live, persists the results, and serves them from the database from then on.
• Configurable cache staleness - how long a cached query is considered valid (default: 600 seconds / 10 minutes) is stored in app_settings and adjustable at runtime via an authenticated endpoint.
• Generated API key auth - a unique API key (sk_live_...) is generated and printed to the console on every server start, required for protected admin actions like updating cache settings.
• Simple REST API - built on Axum, exposing endpoints to search, look up a specific model, list everything indexed, and tune caching behavior.
• Containerized - ships with a Dockerfile and docker-compose.yaml for one-command setup, no local Rust toolchain required.

Prerequisites

Before setting up Ollamadex, make sure you have the following installed:

• Rust & Cargo
• Docker
• Docker Compose

Installation & Setup

1). Clone the repository:

git clone https://github.com/Maddox-RVS/Ollamadex
cd Ollamadex

2). Run it:

Option A - with Docker Compose (recommended):

docker compose up --build

By default the server listens on port 3000. Override it by setting PORT:

PORT=8080 docker compose up --build

Option B - with Cargo:

cargo run --release -- --port 3000

On startup, Ollamadex prints a generated API key to the console, save it, as it's required for admin-only endpoints (see below) and isn't persisted between restarts.

API Reference

GET /search

Searches the local cache for models matching a query, scraping and indexing fresh results from ollama.com if no sufficiently similar cached search exists yet.

Query Param	Type	Required	Description
query	string	Yes	The search term to look up

Example:

curl "http://localhost:3000/search?query=llama3"

POST /find

Looks up a specific model by its ollama.com page path, scraping and indexing it if it isn't already in the local database.

Body:

Field	Type	Required	Description
href	string	Yes	The model's page path (e.g. "/library/llama3.3")
model_name	string	Yes	The model name to scrape with

Example:

{
  "href": "/library/llama3.3",
  "model_name": "llama3.3"
}

GET /all

Returns every model currently indexed in the local database.

No parameters required.

POST /cache_stale_seconds

Updates how long (in seconds) a cached search is considered fresh before a new scrape is triggered. Requires a valid api_key.

Body:

Field	Type	Required	Description
cache_stale_seconds	i64	Yes	New staleness threshold, in seconds
api_key	string	Yes	Server-issued API key (printed on startup)

GET /cache_similarity_threshold

Returns the current similarity threshold (0.0–1.0) used to decide whether an incoming query is "close enough" to a previously cached search to reuse its results instead of re-scraping.

No parameters required.

Example response:

{ "cache_similarity_threshold": 0.85 }

POST /cache_similarity_threshold

Updates the similarity threshold used for cache matching. Requires a valid api_key.

Body:

Field	Type	Required	Description
cache_similarity_threshold	f64	Yes	New threshold, must be between 0.0 and 1.0
api_key	string	Yes	Server-issued API key (printed on startup)

Example:

{
  "cache_similarity_threshold": 0.9,
  "api_key": "your_api_key"
}

Database Schema

Ollamadex uses a structured SQLite relational database consisting of four main tables to handle application configuration, query caching, indexed models, and their respective architectural variants.

1. app_settings

Stores persistent global key-value configuration flags.

Column	Type	Constraints	Description
key	TEXT	PRIMARY KEY	Setting name identifier
value	TEXT	NOT NULL	Associated configuration value (e.g., '600' for cache_stale_seconds)

2. search_cache

Caches scrapers' queries with timestamps to prevent unnecessary external hits.

Column	Type	Constraints	Description
id	INTEGER	PRIMARY KEY AUTOINCREMENT	Unique cache record ID
query	TEXT	NOT NULL UNIQUE	Scraped query string
searched_at	TEXT	NOT NULL	ISO 8601 formatted timestamp

3. models

Contains metadata indexing the main, parent LLM families.

Column	Type	Constraints	Description
id	INTEGER	PRIMARY KEY AUTOINCREMENT	Unique parent model ID
name	TEXT	NOT NULL	General model name (e.g., "llama3")
description	TEXT	NOT NULL	Description scraped from ollama's website
capability_tags	TEXT	NOT NULL	Capabilities serialized as a JSON array
size_tags	TEXT	NOT NULL	Parameter size tags serialized as a JSON array
cloud_tag	BOOLEAN	NOT NULL	Boolean flag indicating cloud availability
url	TEXT	NOT NULL UNIQUE	Direct URL link to the model page on ollama's website

4. model_variants

Tracks individual weights, parameter configurations, and context sizes linked to parent models.

Column	Type	Constraints	Description
id	INTEGER	PRIMARY KEY AUTOINCREMENT	Unique variant ID
model_id	INTEGER	NOT NULL, FOREIGN KEY	References models(id) ON DELETE CASCADE
model_identifier	TEXT	NOT NULL	Full reference string (e.g., "llama3:8b-instruct-q8_0")
size	TEXT	NOT NULL	File footprint size on disk
context	TEXT	NOT NULL	Supported sequence context length limit
input	TEXT	NOT NULL	Accepted input formats / modalities
url	TEXT	NOT NULL	Direct tag manifest page reference URL
