Build a web scraper in minutes—zero coding required

Step 1: Describe your scraper

Open a new chat with Replit and explain what you want in plain language, like “Create a Python app that visits example-store.com, collects product titles, prices, and links, then saves them to a CSV file every morning.” Add details such as email alerts or run frequency, and share a sample page URL if it helps.

Step 2: Review and approve the plan

Replit replies with a clear outline that lists the tools it will install, the folder structure, and a preview of the logic. Review the proposal, check the sample output shown in Preview, then click Approve to give it the green light.

Step 3: Let Replit build your app

Watch as Replit sets up the environment, installs the necessary libraries, and writes the scraper, scheduler, and mailing script. It also configures secrets for your email credentials and drops a sample CSV in your workspace so you can confirm the format right away.

Step 4: Test the app and request changes

Hit Run to execute the scraper, view logs, and confirm the data looks right. Need an adjustment? Click the element you want to change in Preview and ask Replit to refine the selector or add a JSON export—the update appears almost instantly.

Step 5: Schedule your scraper and let it run

Convert the project to a scheduled deployment. Choose a custom domain or keep the default URL, set the interval, and your scraper starts collecting data automatically. Whenever you need an update, open the same project, chat with Replit, and redeploy in minutes.

Tips for building a web scraper with Replit

Keep data tidy with the built-in database

Storing results in the built-in database or Postgres keeps your information searchable and persistent. Prompt Replit to create a table with different variables, then insert a new row on each run. You’ll be able to inspect trends directly in the editor or expose the data through an API later.

Let Replit pick the right libraries

You don’t have to name every dependency. Describe the outcome—such as “download pages, respect robots.txt, and parse product details”—and the AI selects reliable packages automatically. That way, you can focus on the data rather than package management.

Run scrapers on a schedule

Once the code works, turn it into a deployment so it can run without supervision. Attach a schedule—say, every hour for a price tracker—and Replit handles the rest: start the process, collect data, shut it down, then repeat.

Share examples as a guide

Providing real examples clarifies what the code needs to extract. Paste a short block of markup or a screenshot of the target page in your prompt so the AI can craft accurate selectors.
