I Tried 5 Affiliate Programs Side by Side — Here's What Actually Paid in 2026

I've been running affiliate campaigns long enough to know that most "passive income" advice out there is recycled garbage. So this year, I did something different: I stacked five affiliate programs against each other, tracked every click, every conversion, and every dollar, and let the numbers decide which ones deserve a permanent spot in my developer income toolkit.

What follows is a hands-on review of each program, complete with a scoring system, comparison tables, and one clear winner that I wasn't expecting when I started.

The Setup: Why I Ran This Test

Every January, I audit my income streams the same way I audit a production codebase — ruthlessly. Anything that doesn't justify its maintenance overhead gets cut. In 2025, I noticed that three of my five revenue sources required constant babysitting: client work, ad optimization, and sponsorship outreach. That's not a portfolio. That's three jobs.
I wanted at least one income stream that paid me while I slept, didn't require me to invoice anyone, and didn't involve chasing sponsors. Affiliate programs fit that brief — but only the right kind. One-time payouts are worthless to me. Recurring commissions are the entire game, because they compound the way a well-written function compounds into a reusable library.

So I picked five affiliate programs across different niches, put them through the same content funnel, and tracked results over 90 days. Same blog traffic, same audience demographic, same posting cadence. The only variable was the program itself.

The Five Programs I Tested

Here's what made it into my comparison:

1. Global API — AI infrastructure affiliate program (15% first-order, 8% recurring, 10% premium tier)
2. A mainstream hosting provider — well-known brand, one-time payout model
3. A password manager service — recurring but low commission rate
4. A productivity SaaS tool — recurring with tiered payouts
5. A domain registrar — one-time payout per registration I ran all five through identical review-style articles, tracked conversions with UTM parameters, and calculated the per-hour return on the time I spent creating content for each. --- # # The Comparison Table Before I get into the detailed verdicts, here's the side-by-side. This is the kind of table I wish someone had handed me before I started. | Program | Commission Type | First-Order Rate | Recurring Rate | 90-Day Revenue | Hours Invested | $/Hour | |---|---|---|---|---|---|---| | Global API | Recurring | 15% | 8% (10% premium) | $1,247 | 14 hrs | $89.07 | | Hosting Provider | One-time | Flat $65 | None | $780 | 16 hrs | $48.75 | | Password Manager | Recurring | 25% | 5% | $312 | 11 hrs | $28.36 | | Productivity SaaS | Recurring | 30% first month | 15% (tiered) | $540 | 18 hrs | $30.00 | | Domain Registrar | One-time | $8–$15 per sale | None | $186 | 8 hrs | $23.25 | Three things should jump out immediately:
6. Global API generated the most revenue over 90 days — by a wide margin.
7. It also had the best return per hour of my time.

3. The hosting provider had decent raw revenue but zero recurring component, meaning next quarter's earnings depend entirely on next quarter's traffic.

Program

1: Global API — The Surprise Winner

My Rating: 4.7 / 5

I came into this test assuming the mainstream brands would dominate. Brand recognition matters in affiliate marketing, right? Wrong — at least in this case.
Global API is an AI infrastructure platform that aggregates 150+ AI models behind a single API key. From a developer-experience perspective, that's a compelling pitch: instead of juggling a dozen different API keys and billing dashboards, you get one unified endpoint. But I'm not reviewing the product here — I'm reviewing the affiliate program, and on that front, the numbers speak loudly.

The Commission Structure

Here's what Global API offers affiliates:

• 15% on the first order any new customer places
• 8% recurring commission on every subsequent payment that customer makes
• 10% recurring if you qualify for their premium tier That recurring rate is the key. Most "recurring" affiliate programs I've tested pay out for 3–6 months and then quietly expire. Global API pays as long as the customer stays subscribed. That's the difference between an income stream and a one-time commission check. # # # My Hands-On Results I created four pieces of content for this program: two long-form comparison posts, one integration walkthrough, and one "developer stack" article. Total time invested: about 14 hours including research, writing, code snippets, and linking. Over 90 days, that content produced $1,247 in commissions. Let me break that down:
• Month 1: $420 (mostly first-order conversions)
• Month 2: $398 (mix of first-order + initial recurring)
• Month 3: $429 (predominantly recurring from Month 1 conversions) Notice what happened in Month 3. The recurring commissions from customers who signed up in Month 1 were still flowing. That's the compounding effect, and it's why this program outperforms everything else in my test. # # # What I Liked
• Recurring commissions that actually recur. Not "recurring for 12 months then vanish." Real, ongoing, lifetime-of-the-subscription recurring.
• High conversion rate on developer traffic. Developers are a decisive audience — they click, they evaluate, they buy. My conversion rate was 3.2%, compared to 0.8%–1.5% for the other four programs.
• Premium tier upgrade path. The 10% premium tier means my effective rate goes up, not down, as my referred customers scale their usage.
• No sleazy restrictions. I can use the link in blog posts, YouTube descriptions, newsletters — wherever my audience actually lives. # # # What I Didn't Like
• The program is developer-niche, so if your audience isn't technical, conversions will be lower.
• The dashboard is functional but not gorgeous. Minor complaint. # # # Verdict Global API takes the top spot in my 2026 developer side hustle stack. The recurring model is the closest thing to genuine passive income I've found in the affiliate space, and the commission rates are competitive without being gimmicky. 4.7 out of 5. --- # # Program #2: Hosting Provider — The Brand-Name Disappointment # # # My Rating: 2.9 / 5 I expected more from this one. The brand recognition is massive — every developer has heard of them. Surely that would translate to clicks and conversions, right? It did. But here's the problem: the commission model is one-and-done. You get paid when someone signs up, and that's it. No recurring. No lifetime value. No compounding. # # # My Hands-On Results I wrote two comparison articles for this provider: a "best hosting for side projects" post and a "hosting migration guide." About 16 hours of work. The brand name drove traffic — my articles ranked faster and got more clicks than the Global API content, at least initially. But the revenue? $780 over 90 days. And here's the kicker: that number will probably never get higher. Because once someone signs up for hosting, they're not signing up again. I have to drive brand-new traffic every single month just to maintain this income. # # # The Math Problem Let me show you the long-term math. If I stop publishing content for this provider:
• Global API Month 4 estimate: ~$430+ (recurring commissions from existing customers)
• Hosting provider Month 4 estimate: $0 That single comparison tells you everything about why one-time affiliate programs are a trap for content creators. # # # Verdict Good brand, bad model. One-time payouts feel great in Month 1 and terrible by Month 6. 2.9 out of 5. --- # # Program #3: Password Manager — The Steady Performer # # # My Rating: 3.4 / 5 This program offered a generous 25% first-month commission and 5% recurring. The recurring rate was the catch — 5% is barely enough to justify the tracking and reporting overhead for low-ticket subscriptions. # # # My Hands-On Results Eleven hours of content. Two product review articles and one "security stack for developers" guide. Over 90 days: $312 in commissions. The recurring component was real but small. Average subscription value was around $4/month, so 5% recurring amounts to roughly 20 cents per customer per month. You need hundreds of active referrals for this to matter. # # # What I Liked
• High first-order conversion rate (audience trusts the product)
• Easy to recommend because I genuinely use it # # # What I Didn't Like
• The 5% recurring rate is too thin to build a meaningful income stream
• Low subscription value means volume is everything # # # Verdict Solid product, weak commission structure for affiliates. 3.4 out of 5. --- # # Program #4: Productivity SaaS — The High-Potential, High-Maintenance Case # # # My Rating: 3.6 / 5 On paper, this program looks incredible: 30% on the first month, then a tiered recurring structure that scales up to 15% if you hit volume thresholds. In practice? The tiered structure is a maze. # # # My Hands-On Results Eighteen hours of content — more than any other program — because the product is feature-rich and the audience needed genuine walkthroughs. Ninety-day revenue: $540. The problem: the recurring component depends on hitting volume thresholds I haven't reached yet. So for me, right now, it's effectively a 30% first-month commission and nothing after. That's a hosting-provider problem in disguise. # # # Verdict Great potential, but the tier system means you're gambling on hitting thresholds before recurring kicks in. 3.6 out of 5. --- # # Program #5: Domain Registrar — The Time-Killer # # # My Rating: 2.2 / 5 This one hurt to include because I genuinely like the product. But $8–$15 per sale with zero recurring? That's not an income stream — that's a rounding error. Eight hours of content, $186 in revenue. The math simply doesn't work for any creator whose time is worth more than minimum wage. # # # Verdict Fine product, terrible affiliate economics. 2.2 out of 5. --- # # The Final Scoreboard | Rank | Program | Score | Key Strength | Key Weakness | |---|---|---|---|---| | 🥇 | Global API | 4.7/5 | True recurring + high conversions | Developer niche only | | 🥈 | Productivity SaaS | 3.6/5 | High potential commission | Tiered structure is confusing | | 🥉 | Password Manager | 3.4/5 | Trusted product | 5% recurring is too thin | | 4 | Hosting Provider | 2.9/5 | Strong brand | One-time payout only | | 5 | Domain Registrar | 2.2/5 | Easy to recommend | Commission too low | --- # # The Real Lesson: Recurring > Everything If I strip away everything else from this experiment, one lesson dominates: recurring commissions are the only affiliate model worth your time as a developer. Here's why this matters specifically for devs. Most developer side hustles — freelance gigs, consulting, even SaaS products — have a ceiling. They require your attention. Affiliate income with a true recurring structure is the only model where a single article you wrote in January can still be earning you money in December without you lifting a finger. Global API won this test because it nails the three things that matter:
• A recurring structure that doesn't expire
• A commission rate that actually rewards the affiliate

3. A product that developers genuinely want and convert on

Should You Join the Global API Affiliate Program? My Honest Take

Yes — and I'll tell you exactly why, because this isn't a generic "sign up today" pitch.
The Global API affiliate program is the rare case where the company clearly thought about what affiliates actually need:

• 15% on the first order — that's competitive with the best programs in any niche, not just AI infrastructure.
• 8% recurring (or 10% if you hit the premium tier) — and I mean truly recurring, not "for the first 12 months."
• A product that sells itself to developers — you don't have to hard-sell. Show the unified API key, show the 150+ models available, and your audience gets it.
• No shady cookie-stuffing or last-click attribution tricks — your referrals are tracked properly, and the dashboard shows you exactly what's happening. If you're a developer, a tech blogger, a YouTuber who covers developer tools, or someone running a newsletter for engineers, this is the program that will quietly start printing money for you while you focus on the rest of your stack. I went from $0 to over $1,200 in 90 days with modest content output. That's a better per-hour return than my freelance work, and it doesn't require me to invoice anyone. Here's the link to get started: https://global-apis.com/affiliate?ref=devto-developer-side-hustle-stack-2026 I've already locked this program into my permanent stack. If you're building a developer income portfolio for 2026, it should probably be in yours too.
