- I have a couple open source projects, and hosted "webmaster tools" type projects, with one-page websites like http://www.daterangepicker.com that get ~10K visits/day, and run one AdSense ad on each page, which brings in a couple hundred dollars most months.
- I run a web store where I resell another company's products (with permission) targeted at a different customer group than their own website. I advertise it on Google AdWords and Bing Ads on just a handful of keywords. Fulfillment is automated through the other company, so I haven't touched the store except to update the design every few years, and it brings in $500-$1000/month in profit. Sorry, don't want to link to this one, too easy to copy.
- Dividends from stocks and high-dividend-yield index funds are totally passive. But first you have to earn and save the money to invest in them. I also have some money in REITs, investing in real estate without having to buy and manage the real estate.
- I used to run some referral ads on my sites for a merchant account provider I used 5-10 years ago. A couple businesses signed up through those links and still use that company for their credit card processing. The commission agreement was a lifetime residual based on their monthly processing volume... I'm still getting $100-200 transferred into my bank every month from that company even though I haven't been referring anyone to them for years.
Also as a side note, thank you for daterangepicker! I've integrated it into a couple little things I've built like chrome extensions and absolutely love it.
* Improvely got its first customers from Google ads. Because Improvely has a high CLV (customer lifetime value), I could spend a lot on advertising to acquire a customer and still make money from it. So that's what I did. Once I had a couple dozen customers, who were all delighted with the product and the support, word of mouth started taking over. These days 90% of new signups are referrals from an existing/past customer, or referrals from some website that's written an article or review mentioning Improvely. I still run some Google ads but with a limited budget.
* The open source projects get their traffic from Stack Overflow, forums, people searching NPM and other repositories, etc. The Date Range Picker widget got its initial traffic from a "Show HN" post I did here.

I've started other SaaS apps that never worked out. The thing that made them different from Improvely and W3Counter is that nobody was super excited about them. Nobody loved those products; they were maybe useful but not the best at anything and not particularly unique. So the word of mouth referrals never came, churn was high, and eventually I shut them down and tried something else.
We need more stories and details about such endeavors, but unfortunately most don't write about it.
Btw, how do you monetize the Date Range Picker?
The AdSense ad on the documentation website
It gets quite a bit of traffic -- https://www.w3counter.com/stats/90840/dashboard
Yes, although this is irrelevant regarding monetization (with adsense).
Anyway, I'll get this started even though it's not what you're probably looking for: my best passive income is rental properties. I purchased a small house in Florida that is now renting for all costs + a few hundred a month, and will be adding a second property in a few months. It's about as low-maintenance as a SaaS side business and required basically zero marketing to get a "user".
I don't have any real passive income, myself, but one of my buddies has a pretty sweet setup.
He wrote a bunch of trading bots that would automatically perform arbitrage between all of the bitcoin exchanges. He wrote a variety of bots with different strategies, and then he would lease them out to people and take a cut of the profits (in addition to doing his own arbitrage trading with his extra money). From the sound of it, he was making some serious cash (like thousands of dollars a day).
By far the best passive income so far this year.
As someone who commutes via ferry, I got sick of checking the official schedule of my ferry because it's not mobile friendly and was slow. Then I noticed more of the official schedule sites are typically in pdf, slow, not optimized for mobile devices or all of the above. So I've been slowly putting some of the schedules on this site over the past week. While not fully passive, the schedules will only have to be updated a couple of times per year since they change fairly infrequently.
It is just monetized via Google Adsense right now, but already paid for itself with a couple of ad clicks and when all said and done it should be some decent beer money every month.
Next steps are to learn how to automate the monitoring of the official schedule sites, so I can automate the updating of my site to match the official schedules. That would make it more passive.
If the pdfs are published as scans like so many municipalities do, then OCR is the only way to go.
Either way, good luck and decently nice design.
Regarding the design, I just wanted to get something out the door quickly with a suitable look out of the box, so I decided to use MaterializeCSS (http://materializecss.com/). It's getting the job done so far, but I may revisit the design after I get all the content up.
And I'll look into poppler. Thank you for the recommendation.
1) ~45% - Two hand-selected ads on a major developer website. These were individual deals with the companies placing the ad.
2) ~5% - Ad network ads on two websites.
3) ~45% - Rental income from my house on AirBnB.
I wish I could say that these were clever projects or startups, but I haven't yet found a "traditional" software side project that makes money. I have one that's been running for a little over a year, although I haven't figured out how I want to actually charge for it. People are just using it on a free tier right now.

Supposedly has an 18% yield, which is pretty darn good. What's the catch?
Can you elaborate on `expensive to own`? The taxes are a little onerous, but maybe you mean something beyond that.
And these are truly passive in the sense that the hard work of building the site is done, and I only have to do a quick updated once each year and then sit back and rake in ... hundreds!
I'd consider passive something that requires virtually no involvement: stocks, bonds, real estate, etc
Stock > Job > Books > Affiliate Websites
Stocks are auto-invested each month.
Job is not passive.
Books were written a while ago. Some by me most by others. Probably a couple hours a week evaluating how they're doing. Sometimes I'll do sales, etc. Less passive as I'm trying to grow their revenue.
Affiliate websites are all 100% passive at this point. I automatically generate content for them. Maybe an hour or two updating the VPS/WP.
~5k is auto invested in an index/mo.
