7 open source repos to resell as a service, with the price list and the pitch
Seven free open source tools (CRM, SEO, competitor monitoring, site rebuild, reporting, scraping, OCR), each turned into a service billed from 4,000 to 12,000 dollars. The suggested price, the client pitch and the setup for every repo.

You do not need to build a SaaS to sell software. Seven GitHub repos, free and under commercial-friendly licenses, already do the work an agency bills thousands of dollars for: a CRM, an SEO audit, competitor monitoring, a site rebuild, a report engine, a lead machine, a document extractor. Your product is the setup, the configuration and the result delivered to the client. The code already exists.
For each repo, this article gives you what the tool does, the service you sell, the suggested price, the pitch you say to the client, and the setup. All seven were verified on September 8, 2026 (license, stars, activity).
The Claude AI Lab is my Skool community where I share my Claude systems and the more advanced modules. Access is $67/month.

The prices below are not market rates, they are suggested selling prices. They follow one rule: you bill the problem solved, never the time spent or the price of the software (zero). An 8,000-dollar CRM compares to the salesperson who stopped following up, not to a HubSpot subscription.
Every service sells in two formats: a one-time setup (the price shown), and for tools running continuously, a monthly retainer turning the sale into recurring revenue.
The seven services
The agent-driven CRM
What the tool does. An open source CRM designed for AI agents (MIT license, 10,000 stars). Records update, deals move and follow-ups go out without a human clicking through the pipeline.
What you sell. A sales pipeline maintaining itself, for a small business whose salespeople never fill in the CRM.
Suggested price. $8,000 for the setup, then $800 per month for support and improvements.
Pitch: "Your salespeople spend their time selling, not filling in a CRM. I install a pipeline updating itself from emails and calls, and following up with the prospects everyone forgot. In thirty days, not a single lead sleeps in a spreadsheet."
Setup. Clone the repo, follow the README (Bun runtime, Postgres database), connect the client's mailbox, import their existing contacts. Plan two days with Claude Code.
The monthly SEO audit
What the tool does. The open source alternative to Semrush and Ahrefs (MIT, 17,000 stars): rank tracking, technical site audit, keyword research, with an AI agent working on the strategy.
What you sell. A monthly SEO report with rankings, pages to fix and keyword opportunities, for a site nobody has ever tracked.
Suggested price. $6,000 for the initial audit and setup, then $500 per month for the report and rank tracking.
Pitch: "You do not know which keywords you rank for or why your competitor sits above you. I set up tracking on your rankings and deliver, every month, the three fixes bringing the most traffic."
Setup. Deploy the tool on your server, add the client's domain and their twenty priority keywords, schedule the monthly export. The first audit comes out in a day.
Competitor monitoring
What the tool does. It watches any web page and sends an alert (email, Slack, Telegram, webhook) the moment it changes (Apache 2.0, 33,000 stars). Prices, stock, content, job postings, anything moving.
What you sell. Competitor and price monitoring: the client knows the same day when a rival changes prices, launches an offer or hires.
Suggested price. $4,000 for the setup, then $400 per month. This is the subscription nobody cancels, because nobody wants to go blind again.
Pitch: "Your competitor changed their prices three weeks ago and you heard it from a customer. I monitor their pricing pages, new products and job posts, and you get an alert the same day."
Setup. One Docker container, the list of pages to watch, the client's alert channel. Half a day, then a monthly check-in to adjust the list.
The site rebuild
What the tool does. Give it a URL and your coding agent rebuilds the site in clean Next.js, in one command (MIT, 34,000 stars). The result is a healthy base to customize, not a copy to deliver as is.
What you sell. A fast website rebuild for a business with an aging site, with the prototype ready before the first meeting.
Suggested price. $6,000 for the rebuild, hosting and maintenance optional at $150 per month.
Pitch: "I rebuilt your website before our meeting, it is live, faster and readable on mobile. What is left is validating your copy and colors, and you are online next week."
Setup. Run the command on the prospect's site, then replace the copy and images with content they own: the clone is the structure, never the final deliverable. Plan a day of customization.
The report engine
What the tool does. It turns a document or a topic into a real PowerPoint, with native shapes, charts and animations (MIT, 52,000 stars). The file opens and edits in PowerPoint like any other deck.
What you sell. Automated client reporting: every month the numbers go in, a clean deck comes out, with no Friday night spent on slides.
Suggested price. $5,000 for the template and pipeline setup, then $300 per month per automated report.
Pitch: "Your team spends two days a month putting numbers into slides. I connect your data to an engine producing the report in your agency's format, ready to send on the first of the month."
Setup. Build the template in the client's colors, connect the data source (CSV export, spreadsheet, API), schedule the monthly generation. Two days.
The lead machine
What the tool does. An adaptive web scraping framework in Python (BSD 3, 79,000 stars): it keeps working when a site changes its layout and gets past common anti-bot protections.
What you sell. A prospect list refilling itself every week, from the directories, marketplaces and listing sites of the client's industry.
Suggested price. $10,000 for the setup, then $1,000 per month for the weekly list and enrichment.
Pitch: "Your salespeople hunt for prospects by hand. I build a collection delivering a fresh, deduplicated list every Monday, with the website, the email and the signal justifying the call."
Setup. Write one spider per source with Claude Code, add deduplication and the export to the client's CRM. Plan three days, and check the terms of use of every source before collecting.
Document extraction
What the tool does. An OCR engine turning a PDF or a scan into structured data (Apache 2.0, 89,000 stars), including tables and multilingual documents.
What you sell. The end of retyping: invoices, contracts, intake forms arriving as clean data in the client's software, instead of being retyped by a full-time person.
Suggested price. $12,000 for the setup, then $600 per month for processing and corrections. The highest price on the list, because it replaces a position.
Pitch: "Someone at your company retypes invoices all day. I set up a flow where the document arrives by email and comes out as lines in your accounting software, with a human check only on doubtful cases."
Setup. Deploy the engine, define the fields to extract per document type, connect the input (mailbox, shared folder) and the output (spreadsheet, ERP). Three to five days depending on the number of formats.

How to sell the first one
Going further
The seven repos are public, their READMEs are current and their communities active. Open the first one matching a problem you hear from your clients, install it with Claude Code this week, and send a demo to three businesses. The first positive reply is worth more than three months of building a SaaS.
