Two videos ago, I showed you 10 free GitHub repos that quietly replace tools you're paying thousands for. It did 22,000 views, then part two, 10 more. And in the comments, you kept naming the same thing, the bills that actually run a business. Your CRM, your design tool, your analytics, your e-signatures, your password manager. So, this is part three, and it's the most expensive stack yet. 10 free open-source repos that together replace over $180,000 a year of software. Real repos, real screens. I pulled up every single one and for each, I'll show you exactly how to stand it up yourself in a weekend. Let's go.
Number one, 20. This is a modern open-source CRM. And the second you open it, you'll think you're looking at a paid product. Around 50,000 stars on GitHub. You get a Notion-style deal pipeline. You drag cards across custom objects, a clean record timeline, keyboard shortcuts, even an API and webhooks. What does it replace? Salesforce. And Salesforce starts at $100 per user per month, climbing to $165 for enterprise. For a five-person sales team, that's $6 to $10,000 a year. Gone. Here's how you run it this weekend. Clone the repo, one docker-compose command, and it's live on localhost. Point it at a managed PostgreSQL, add a domain, and your whole team is on it by Monday. Honest catch, it's AGPL. And a few deep enterprise features aren't there yet. But for a startup tracking deals, you will not miss Salesforce.
Number two, Appsmith. Every company eventually builds ugly internal tools, admin panels, dashboards, support consoles. Most teams pay Retool $50 per user per month to do it. Appsmith is the free open-source version, thing around 40,000 stars. You drag widgets onto a canvas, tables, forms, charts, buttons, bind them to any database or REST API, write a little JavaScript, and you've got an internal app in an afternoon. The builder looks and feels exactly like Retool. 10 builders on Retool Business is $6,000 a year. Appsmith is zero, unlimited seats. We can set up one docker run with the appsmith/community image. Open the editor in your browser. Connect your PostgreSQL or MySQL and build. Self-hosted means your customer data never leaves your servers, which is the real reason teams switch. Honest catch. Very heavy apps can feel sluggish, so keep each tool focused. But for the admin panel you keep putting off, that's a Saturday.
Number three, Apache Superset. And this is the giant killer. 70-plus,000 stars, originally built inside Airbnb, now a top-level Apache project. It's full business intelligence. A SQL Lab where you query your warehouse, then turn any query into one of 40-plus chart types, then drop those charts into dense, interactive dashboards. The screen I pulled up looks like a Fortune 500 analytics suite. What does it replace? Tableau at $75 per user per month or Looker, which enterprises pay $60 to $150,000 a year for. This single free repo erases that line item. We can set up clone, docker-compose up with their image tag file, login and point it at PostgreSQL, BigQuery, Snowflake, whatever you've got. Honest catch. First setup has more moving parts than the others. So read the docs, but once it's running, your whole company gets dashboards for the price of the server it sits on.
Number four, DocuSeal. This one gets the loudest. "Wait, that's free?" DocuSign charges $45 per user per month just to send documents for signature. DocuSeal does the same thing. Open source, about 17,000 stars. You upload a PDF, drag signature, date, initial, and text fields right onto it. Send a link and the signer fills it in from any device with a full audit trail and a tamper-proof completed document. The field editor on screen is genuinely as smooth as DocuSign's. Three users on DocuSign is over $1,600 a year. You stop paying. And the deploy is the easiest in this whole video. One docker run docuseal/docuseal and you have a working e-signature platform. That's not a weekend, that's a coffee break. Honest catch. It's leaner on integrations than DocuSign's enterprise tier. But for contracts, NDAs, and onboarding their paperwork, it is more than enough, and it's yours.
Number five, Penpot. Designers, this one's for you. Penpot is open-source design and prototyping. Around 50,000 stars, and it's a real Figma alternative, not a toy. Vector editing, components, multiplayer cursors, so your team designs together in real-time, prototyping, and a developer handoff mode that spits out the CSS. Because it's built on open web standards, the code it generates is clean. It replaces Figma, which is $16 per editor per month, about $1,900 a year for a 10-person design team. Weekend setup. Grab their docker-compose file, bring it up, and your team opens it in the browser. No installs. You can even keep your design files completely in-house, which agencies and regulated companies love. Honest catch, the plug-in ecosystem is smaller than Figma's, and a few power features lag. But for 90% of product design work, your team can move over and never look back.
Number six, Aine. Around 70,000 stars and it's two paid tools in one. It's a Notion-style docs and database workspace and an infinite whiteboard like Miro. And the magic is they're the same canvas. You can take a document block and drop it straight onto the whiteboard. So your notes and your diagrams live together. It's local-first, meaning it works offline and your data sits on your machine, not someone else's cloud. That replaces Notion at $18 per user per month. Plus the separate Miro subscription you'd otherwise stack on top for a 10-person team. That's well over $2,000 a year. Weekend setup. A single Docker command pulls the Aine image and you're running your own workspace. Point it at storage and invite the team. Honest catch, real-time multiplayer is still maturing versus Notion. But if you want your second brain to actually be yours, offline, private, and free, this is it.
Number seven, CAP. If your team runs on Loom, watch this. CAP is open-source screen recording, about 18,000 stars, and it's beautiful. Record your screen and camera. Get an instant sharable link with the video, a transcript, and comments, or export a high-quality local file. The share page looks just like Loom's. Loom Business is $12 to $15 per creator per month for a five-person team. That's around $900 a year. CAP is free and because you can self-host the sharing infrastructure, your internal walkthroughs and customer recordings never sit on a third-party servers. Weekend setup, the desktop app works on Mac and Windows out of the box. And for team sharing, you deploy their server with docker-compose or one-click on Railway, then point the app at it. Honest catch, the self-hosted sharing stack is newer than the polished desktop app, but for async standups, and quick demos, CAP fully replaces Loom.
Number eight, Listmonk. This is the one that kills the most boring, painful bill. Email. Mailchimp charges by your list size. $100 a month at 5,000 subscribers, climbing past $270 as you grow. Listmonk is a free open-source newsletter and mailing list manager, about 22,000 stars, and it is blisteringly fast because it's a single Go binary. You import subscribers, build campaigns, segment with SQL-style queries, and watch opens, clicks, and bounces on a live dashboard. Plug it into Amazon SES and you're sending email for pennies per thousand instead of hundreds a month. Weekend setup, docker-compose up with Listmonk and PostgreSQL. Set your SMTP or SES credentials. Import your list and send. Honest catch. You manage your own sending reputation and deliverability, which Mailchimp babysits for you. But if your list is growing and the bill is scaling right along with it, this pays for itself in week one.
Number nine, Qdrant. Must I take you? And this is the one for anyone building with AI. Every AI app that does search, memory, or retrieval needs a vector database, and most people reach for Pinecone, which starts around $50 a month and climbs fast with usage. Qdrant is a free open-source vector database written in Rust, around 30,000 stars, and it is fast. It ships with a built-in web dashboard where you can actually see your vectors plotted in space, run searches and inspect collections. The most visually striking screen in this whole video. It replaces Pinecone and pricey Algolia search tiers, and at scale, that's hundreds to thousands of dollars a month back in your pocket. The deploy is the cleanest here. Docker run -p 6333 qdrant/qdrant, one line, and your vector database is live with the dashboard at localhost. Honest catch, you run the infrastructure yourself. But for a side project or a startup's retrieval pipeline, Qdrant is genuinely excellent and free.
Number 10, Vaultwarden. Your team is almost certainly paying for a password manager. 1Password Business is around $8 per user per month. 20 people is roughly $1,900 a year. Vaultwarden is a lightweight open-source server, around 60,000 stars, that speaks the Bitwarden protocol. And here's the kicker. Every official Bitwarden app and browser extension works with it because to the apps, it just looks like Bitwarden. So your team gets the polished clients while you quietly host the vault. You get unlimited users, organizations, sharing, and two-factor features the paid tiers gate behind upgrades. Weekend setup is famously easy. One docker run with warden/server behind HTTPS. Install the normal Bitwarden extension. Point it at your domain. Done. Honest catch. You're now responsible for backups and locking down that server. So, do it properly. But for a small team that just balked at another per-seat password bill, this is the answer. And it's been battle-tested by tens of thousands of self-hosters.
So, there it is. 10 free open-source repos: 20, Appsmith, Superset, DocuSeal, CAP, Listmonk, Qdrant, and Vaultwarden. Together, they replace over $180,000 a year of software, and every one of them you can stand up in a weekend. I put all 30 repos from parts one, two, and three with the exact deploy commands and links into one free PDF, the Free SaaS Killer Stack. Comment the word "killer" and I'll send it straight to you.
