Cheapest Firebase Alternative for Startups & Indie Hackers (2026)
The cheapest Firebase alternative for most startups and indie hackers in 2026 is Smler, which gives you 15,000 free links a month with unlimited clicks, then plans starting at $9/month once you outgrow the free tier. If you've been digging through Reddit threads or forum posts trying to figure out what replaced Firebase Dynamic Links without the enterprise price tag, that's the short answer.
The rest of this guide breaks down exactly why that's true: a full pricing comparison against Branch.io, AppsFlyer, and Bitly, a look at which service actually has the best free tier, how migration works, and a real cost scenario showing what a growing app would spend over its first year.
What's the Cheapest Firebase Dynamic Links Alternative in 2026?
Smler is the cheapest option because it's the only one of the major alternatives that gives you unlimited clicks, custom domains, and full deep linking on a free plan, then charges a flat, predictable rate after that instead of custom "contact sales" enterprise pricing.
| Provider | Free tier | Starting paid plan | Deep linking included |
|---|---|---|---|
| Smler | 15,000 links/month, unlimited clicks | $9/month | Yes |
| Branch.io | 1,000 clicks/month (not links) | Custom pricing, typically $299+ | Yes |
| AppsFlyer | No meaningful free tier | Custom pricing, typically $500+ | Yes |
| Bitly | 50 links total | $29/month | No |

Why Are Startups Looking for Firebase Alternatives?
Firebase Dynamic Links officially shut down in August 2025, but many teams were already looking elsewhere before that because of how the pricing and product were structured. The common complaints:
- Unpredictable costs: Firebase's pay-as-you-go model can produce unexpected bills the moment traffic spikes.
- Limited free tier: The free Spark plan has restrictions that don't scale with normal early-stage growth.
- Vendor lock-in: Deep integration with Google Cloud Platform makes migrating out painful later.
- Overkill features: Most apps only need deep linking and click analytics, not the entire Firebase suite.
For bootstrapped teams, every dollar matters, which is why "cheapest" and "free tier" show up constantly in Reddit and forum searches about Firebase replacements. To understand how deep linking actually works under the hood before comparing tools, our complete guide to how deep linking works is a useful primer.
Which Deep Linking Service Has the Best Free Tier?
Smler has the best free tier for anyone launching a simple app or hobby project: 15,000 free links per month with no cap on clicks, and no credit card required to start. That combination, unlimited clicks plus a high link cap, is not something Branch, AppsFlyer, or Bitly offer for free.
| Feature | Smler free plan | Branch.io free plan | Bitly free plan |
|---|---|---|---|
| Links per month | 15,000 | Unlimited, but capped clicks | 50 total |
| Clicks | Unlimited | 10,000/month | Unlimited |
| Custom domain | Included | Paid only | Paid only |
| Analytics | Included | Limited | Basic only |
If you're building a hobby app and just need basic routing without getting billed, the free tier alone is usually enough for the first several thousand users.
Best Alternatives to Firebase Dynamic Links for Mobile Apps
Beyond price, the right alternative depends on what your app actually needs. Here's how the main options stack up on the features developers ask about most:
- Smler: Best for cost-conscious teams that want deep linking, custom domains, and analytics without enterprise pricing.
- Branch.io: Strong attribution features but priced for funded startups and enterprises, not indie projects.
- AppsFlyer: Built for large marketing teams running paid attribution at scale, with no real free tier.
- Bitly: Fine for basic link shortening, but it has no deep linking support, so it doesn't actually replace Firebase Dynamic Links.
Our full Firebase migration guide covers the technical differences in more depth if you're comparing API structures, not just pricing.
Can I Use a Custom Domain Without Paying a Fortune?
Yes. Smler includes custom branded domains on the free plan, which is unusual, most competitors treat custom domains as a paid or enterprise-only feature. You can point a subdomain like go.yourapp.com at Smler in minutes rather than paying for a separate branding tier.
Setup takes about 5 minutes following our custom brand domains guide. If you also need root domain redirects, our root routing guide shows how to send visitors from your bare domain to a specific page.
What Features Do Indie Developers Actually Need?
Smler focuses on the features that matter for small teams, without the bloat of a full attribution suite.
1. Universal Deep Links
Smler routes users to your app when it's installed, or to the App Store/Play Store fallback when it isn't. That includes iOS Universal Links, Android App Links, and deferred deep linking that preserves context after install. Read our Ultimate Guide to Deferred Deep Linking, or if you're not sure how the two concepts differ, see Deep Linking vs Deferred Deep Linking.
2. Link-Level Analytics
Every click is tracked by geography, device type, browser, OS, and hour-by-hour trends. Our link-level analytics guide walks through what's available without needing a separate attribution platform.
3. Bulk URL Shortening
Upload a CSV or XLSX file to create hundreds of links at once, useful for email campaigns, affiliate programs, or content distribution at scale.
4. Developer-Friendly API
A full REST API lets you automate link creation from your own backend. Our webhooks guide covers real-time notifications for click and conversion events.
How Do I Migrate from Firebase to Smler?
Migrating is straightforward because Smler's API structure is similar enough to Firebase's that most teams only need to change a handful of endpoint calls.
- Export your existing links and note which ones need deferred deep linking behaviour preserved.
- Create matching short links in Smler, either through the dashboard or in bulk via CSV upload.
- Update your app's SDK integration using our iOS integration guide or Android integration guide.
- Test old link paths to confirm redirects and deep link routing behave the same way they did on Firebase.
- Switch DNS for your custom domain once testing is complete.
The full step-by-step process with code samples for both platforms is in our Firebase migration API guide.
What Would You Actually Save? A Real Startup Cost Scenario
Here's what a typical indie mobile app might spend across its first year, based on Smler's published pricing tiers:
- Months 1-3 (MVP testing): 500 links, 10,000 clicks/month, stays on the Smler free tier.
- Months 4-6 (beta launch): 2,000 links, 50,000 clicks/month, on the $9/month starter plan.
- Months 7-12 (growth phase): 8,000 links, 200,000 clicks/month, on the $29/month plan.
Total year one cost with Smler: $0 + ($9 x 3) + ($29 x 6) = $201.
For comparison, Branch.io's typical custom pricing starts around $299/month minimum, which works out to roughly $3,588 for the same year, a difference of about $3,387.
That's enough to fund a freelance designer for a month, run a small paid acquisition test, or cover several months of hosting instead.
What Are the Best Use Cases for Indie Hackers?
Product Launch Campaigns
Create trackable links for Product Hunt, Hacker News, or Reddit launches and see which channel actually drives installs.
App Onboarding Flows
Use deferred deep links to send new users from SMS, email, or ads straight to a specific in-app screen, even if they need to install the app first.
Referral Programs
Generate a unique short link per user, track who referred whom, and attribute rewards accurately without separate attribution software.
Content and QR Marketing
Share branded short links across blog posts and offline materials. If you're printing QR codes for events or packaging, our QR code generator with tracking comparison covers which tools pair well with a link setup like this.
