toapi vs grab
Python web data extraction tools compared
toapi and grab are Python projects for extracting structured data from websites. toapi exposes selected page data through declarative CSS selectors and JSON endpoints, while grab provides HTTP and parsing tools for building task-based scrapers and crawlers.

toapi: Turn Web Pages into JSON APIs
toapi converts web pages into JSON endpoints using declarative CSS selectors. It suits developers who need lightweight, on-demand data extraction without maintaining a separate crawler or database.

grab: Build Python Web Scrapers and Crawlers
Grab is a Python framework for making HTTP requests, extracting data from HTML, and building concurrent crawlers. It suits developers who need reusable scraping workflows with request handling, task queues, and proxy support.

Key differences
- toapi defines fields and API routes with CSS selectors; grab provides HTML queries using XPath and an HTTP client.
- toapi serves extracted results as JSON through Flask; grab organizes scraping work with its Spider framework and task queues.
- toapi fetches and parses pages on demand with caching; grab supports parallel requests, failed-task re-queuing, and optional result caching.
- toapi can combine data from multiple sites behind one API; grab focuses on reusable scraping workflows, including sessions, forms, and proxy support.
- toapi requires Python 3.10 or later; grab's stated target range is Python 2.7 through 3.13.
- Both projects use the MIT license; toapi has 3.6k stars and 241 forks, while grab has 2.5k stars and 273 forks.
Choose toapi if you…
- need to expose selected HTML fields as JSON endpoints with little scraping infrastructure.
- want to define extraction and cleaning rules with CSS selectors.
- need an on-demand service that can combine data from multiple sites behind API routes.
Choose grab if you…
- need an HTTP client and HTML extraction tools in one scraping library.
- want to process many URLs with parallel requests, task queues, and failed-task re-queuing.
- need session cookies, form handling, proxy support, or Redis and MongoDB task queue backends.
