Check this out: six months ago, my "side income" was a joke. I'm talking maybe $180 a month from a half-abandoned SaaS project, a Notion template I made once and forgot about, and the occasional freelance gig I'd squeeze in between debugging my actual products. I had three projects running at once, none of them profitable enough to call a real business.
Then I tried something different. I started writing about the AI tools I was already using to build those projects.
Today, that little experiment pulls in roughly $2,400/month in recurring revenue. Not from a product I built. Not from a course. Not from grinding on Upwork at midnight. From content. From a handful of blog posts and YouTube walkthroughs where I document what I'm actually shipping.
Let me walk you through exactly how that happened, why I think it's the most underrated income stream for indie makers in 2026, and the specific math behind the recurring commission model that made it all work.
My Background: Three Projects, Zero Recurring Revenue
Quick context on who I am, because this matters.
I run three small bootstrapped projects right now. One is a Chrome extension for content creators (about $600 MRR). Another is a niche SaaS for podcast hosts ($300 MRR, and yes, I know that's embarrassingly small). The third is a free tool I maintain because I enjoy it — zero revenue, but it drives traffic to the other two.
I do all of this solo, mostly between 10 PM and 2 AM after my day job, and on weekends. I've been bootstrapping for about three years. I've shipped things that flopped. I've shipped things that almost worked. I'm ambitious but realistic — I don't pretend every idea I have is a winner.
What I am good at is using AI tools. Every single one of my projects leans on AI APIs in some way — text generation for the Chrome extension, transcription assistance for the podcast tool, summarization for the freebie. I'm constantly signing up for new platforms, testing endpoints, and integrating them into real workflows.
That last part is what changed everything for me.
The Accidental Discovery That Became a Real Income Stream
I wrote my first AI tool review in October. It wasn't strategic. I was frustrated trying to figure out which API platform to use for a new feature in my podcast SaaS, and I couldn't find a single honest comparison written by someone who'd actually integrated multiple options. Everything I read was either a listicle written by a generalist blogger or a vendor's own landing page.
So I wrote my own. I documented my experience trying three different platforms. I included screenshots from my actual dashboard. I talked about what worked, what broke, and what surprised me. I published it on a small blog I barely maintained.
That post now drives about 800 visits a month from organic search. Not life-changing traffic, but here's the thing — almost every visitor is a developer looking for the exact solution I needed. They click my affiliate link. Roughly 4% of them sign up. And every signup earns me a recurring commission, every single month, for as long as that developer keeps their subscription active.
I made $87 from that one article in November. Then $143 in December. By month six, that single post was contributing about $260/month on its own.
I wrote three more posts that quarter. Same approach. Real experience. Real numbers. Real screenshots.
The income started compounding.
Why Recurring Commissions Are the Only Model That Makes Sense for Solo Operators
Here's where I need to get a little evangelical, because this is the part most people get wrong about affiliate marketing.
When you're a solo founder or indie maker, your time is the bottleneck. You don't have a sales team. You don't have a content team. You don't have someone else doing the SEO research, the outreach, the social media scheduling. Everything comes out of your head and your calendar.
That means every income stream you build has to be optimised for one thing: revenue per hour of ongoing maintenance.
A one-time commission is a terrible deal for someone in my position. If I write a review for a $50 product with a 20% commission, I make $10 once. Then I have to write another review for another product. Then another. The treadmill never stops. You're constantly creating new content just to stay flat.
A recurring commission flips the entire equation. You do the work once. The income keeps flowing. You can go on vacation. You can spend a month rebuilding your SaaS. The checks still arrive.
Let me put real numbers on this so you can see what I mean.
The main AI API platform I'm affiliated with right now (more on that in a bit) pays 15% on the developer's first order, plus 8% recurring on every subsequent payment, plus 10% on premium tier upgrades. To translate that into something tangible: if a developer signs up and starts at a $50/month plan, that's $7.50 on day one, then $4/month forever after. If they upgrade to a $200/month premium plan, I get an extra $20/month on top of the base recurring.
Now imagine one blog post drives four signups in its first six months. After six months, those four developers are generating roughly $16/month in recurring commissions. Plus, two of them upgraded to premium, adding another $40/month. So we're at $56/month from one piece of content, forever, as long as those developers keep their accounts active.
Multiply that across 15-20 solid pieces of content, and you can see how the numbers stack up. That's how I got to $2,400/month without going viral or hiring a content team.
What Makes a Good Program (And Why AI APIs Specifically)
Not every affiliate program is worth your time. I've been picky, and you should be too.
The criteria I use: the product has to have a real LTV (lifetime value) on the customer side. If people churn after a month, your recurring commission dies. The product has to solve a real problem your audience already has. The commission structure has to reward loyalty, not just acquisition. And the platform has to convert — because a 50% commission on a product nobody buys is still zero dollars.
AI API platforms check every one of those boxes. Developers are sticky customers. Once an API is integrated into a production app, switching costs are enormous — you have to refactor code, re-test everything, update documentation. The churn rate on developer tools is dramatically lower than on, say, a consumer SaaS subscription.
The market itself is exploding. Every indie maker I know is building AI features into their projects. Every agency is pitching AI to their clients. Every startup deck has "AI-powered" somewhere in the first three slides. The demand curve is still going up.
And the products are high-value. Developer subscriptions tend to be in the $30-$200/month range, which means even modest commission percentages produce meaningful monthly checks. A single developer on a $100/month plan pays me $8/month, plus their first order bonus. That one signup covers a week of groceries. Ten of them cover my hosting bill for the year.
The Global API Program I Actually Use
I want to be specific here because I get a lot of "but which platform?" DMs.
The affiliate program I rely on most is Global API. Here's what stood out to me when I was evaluating options:
They offer access to 150+ AI models through a single API endpoint, which is genuinely useful for indie makers like me who don't want to maintain five separate integrations. The platform itself has grown substantially — they're serving tens of thousands of developers globally, and that traction matters because it means the product isn't going to disappear next quarter and leave me with broken affiliate links.
The commission structure is what sealed it for me. You get 15% on the developer's first order, 8% recurring on every subsequent payment, and 10% on premium tier upgrades. For context, a lot of competing programs only pay 5-10% recurring, or they cap your earnings, or they downgrade you after a year. Global API doesn't do any of that nonsense. The 8% recurring is permanent. It doesn't expire. It doesn't tier down based on volume.
I've been an affiliate since November. My dashboard right now shows roughly 140 active referrals — developers who signed up through my content and are still paying customers. My monthly recurring payout from those referrals alone is around $1,900, with the rest of the $2,400 coming from new first-order commissions and premium upgrades as people move up tiers.
That $1,900 in MRR didn't exist eight months ago. I created it by writing about things I was already doing.
What I've Learned After Six Months of Doing This
I want to be honest about what's worked and what hasn't, because I'm not trying to sell you a fantasy.
What works:
Writing about specific use cases. "How I added AI summarization to my podcast SaaS" outperforms "Best AI API 2026" by a factor of ten. Developers searching for solutions to real problems find those posts and convert.
Including actual screenshots and code snippets. I'm not going to show proprietary code from my products, but I'll show API response formats, dashboard views, billing screenshots. That kind of authenticity is what separates a useful review from another SEO content farm piece.
Building an email list alongside the content. I have about 1,800 subscribers on a tiny newsletter where I share what I'm shipping each month. Roughly 30% of my affiliate conversions now come from email, not search. That's more durable traffic than relying on Google's algorithm.
What hasn't worked:
YouTube, for me. I made 12 videos. The production quality wasn't great. The views were mediocre. The conversion rate was actually lower than my blog. I've paused it for now. Maybe I'll try again with better production.
Generic listicles. I wrote one "Top 10 AI APIs" post early on. It ranks for some keywords, but the conversion rate is awful because the visitors are researchers, not buyers. Specific, problem-focused content converts better.
Trying to be unbiased to a fault. Here's a controversial take: if you've actually used a product and it works for your use case, just say so. The "balanced" reviews that list three pros and three cons for everything are forgettable. I'll mention limitations honestly, but I'll also say "this is the one I use and why" without hedging into oblivion.
The Bootstrap Mindset Shift
I want to talk about something that took me a while to internalize.
When you're bootstrapping, you think in terms of products. You build something. You charge for it. You iterate. That's the playbook. It's how I built my Chrome extension and my podcast SaaS, and I'm proud of both.
But products require ongoing maintenance. Every product is a long-term commitment. Every feature request is another hour. Every bug is another Saturday lost. And unless you hit product-market fit hard, the MRR stays small and the burnout risk stays high.
Affiliate revenue is different. It's not a product. It's leverage on the content you create once. It's MRR without the support burden. It's compounding without the maintenance tax.
For indie makers, the ideal portfolio probably includes 2-3 products you actively maintain, plus 2-3 income streams that don't require ongoing engineering work. The latter is what gives you breathing room. It's what lets you take a month to rebuild your SaaS without panicking about revenue. It's what lets you say no to a bad freelance gig because your baseline is covered.
That's what this AI affiliate income has become for me. It's not my primary business. It's the floor under everything else.
The Honest Numbers
I promised I'd share real numbers, so here they are, no rounding:
- November: $87 (one post, just getting started)
- December: $340 (added two more posts)
- January: $620 (consistent posting, one piece went semi-viral on Hacker News)
- February: $1,150 (compounding from existing posts, no new content that month)
- March: $1,680 (wrote a deep technical comparison piece)
- April: $2,420 (current month, still climbing) Roughly 80% of that is recurring. 20% is new first-order commissions and premium upgrades. The recurring portion is the part that matters — it's the part that keeps growing even when I'm not actively creating new content. I've earned roughly $6,300 cumulative over six months. My total time investment is probably 60-70 hours, mostly on the front end. That's an effective hourly rate north of $90, and crucially, the income is still coming in. # # Why You Should Consider Doing This Too If you're a developer, an indie maker, or anyone in the AI tools space who already has an audience — even a small one — you have everything you need to start. You don't need a huge email list. You don't need YouTube subscribers. You don't need to be a "content creator" as your primary identity. You just need to document what you're already building. Write the post you wish existed when you were evaluating tools. Include real screenshots. Share the actual numbers. Be honest about tradeoffs. The income compounds. The maintenance is low. The recurring model aligns with the way developers actually buy tools, which means the retention is strong and the monthly payouts grow on their own. If you want a specific starting point, I'd recommend looking at the Global API affiliate program. It's the one I've been using, and it's the reason I have real numbers to share instead of hypotheticals. Here's what you get: 15% on the developer's first order, 8% recurring on every monthly payment after that (permanent, no caps, no tier-downs), and 10% on premium tier upgrades. The platform gives you access to 150+ AI models through a single integration, which makes it an easy recommendation for the kind of readers you're already writing to. Their dashboard is clean, their reporting is accurate, and payouts have hit my account on time every single month without me having to chase anyone.

But the compounding is real, and if you're already producing content about AI development, there's no reason not to capture some of the value you're creating. That's the whole game, honestly. Build useful things, write honestly about them, and let the recurring revenue stack up while you sleep. It's the closest thing to passive income I've found as an indie maker. And after three years of bootstrapping, that's saying something.
