Run regular expressions safely, even ones you do not trust. Every pattern is evaluated in an isolated worker with a hard time limit, so catastrophic backtracking is stopped cleanly instead of hanging your servers.
Useful for regular expression playgrounds and teaching tools, validating user supplied patterns before saving them, extracting fields from logs and documents, and debugging patterns in delivery pipelines.
The Test Regular Expression endpoint returns data indicating whether the regex matched the input text, the total match count, and detailed match information including matched text, positions, capture groups, and named groups.
Key fields in the response include "pattern" (the regex used), "flags" (regex flags), "matched" (boolean indicating a match), "count" (number of matches), and "matches" (an array of match details including "match", "index", "groups", and "named").
The response data is structured as a JSON object. It contains the regex pattern and flags, a boolean for match status, a count of matches, and an array of match objects, each detailing the matched text, its position, and any capture or named groups.
The endpoint provides information on whether the regex matched the input, the number of matches found, and detailed match data including the matched text, its position in the input, and any capture or named groups.
Users can customize their requests by specifying the regex pattern, input text, and optional flags (like 'g' for global matches) in the query parameters of the GET request to the endpoint.
Typical use cases include validating user-supplied regex patterns, extracting specific fields from logs or documents, debugging regex patterns, and creating interactive regex playgrounds for educational purposes.
Users can utilize the returned data by analyzing the "matches" array to extract relevant information, such as using capture groups for further processing or displaying matched results in user interfaces.
Standard data patterns include simple matches like email addresses or phone numbers, as well as more complex patterns involving multiple capture groups. Users should expect variations in match counts based on the input text and regex complexity.
