Firebase Blaze计划是否可免费突破免费版100连接限制？

Awesome question—this is a trick tons of individual developers lean on, and it’s not a loophole at all—it’s exactly how Firebase’s pricing is designed to work.

Let’s break this down clearly:

Yes, you absolutely can do this (and it’s allowed) #

Firebase’s Blaze (pay-as-you-go) plan has a key perk that makes this a no-brainer for personal projects:

• If your usage stays within the free tier limits (the same ones as the Spark free plan), you pay $0.
• Unlike Spark, Blaze removes the hard cap on concurrent connections (Spark limits you to 100, Blaze lets you go up to 100,000 without hitting a restriction—again, as long as you don’t exceed other free tier limits like bandwidth or storage).

Why this isn’t a "loophole" #

Firebase built Blaze this way to let developers test and scale their projects without financial risk. For indie devs, this is perfect:

• You get access to way more concurrent users for your app without spending a dime
• You unlock extra features that Spark doesn’t offer (like some advanced APIs, custom domain support, etc.)
• Your bill stays at $0 as long as you keep usage within the free thresholds

A few things to watch out for #

While this is totally safe, there are two small gotchas:

• You’ll need to add a payment method to sign up for Blaze, but Firebase won’t charge you unless you go over the free limits.
• Keep an eye on your usage in the Firebase Console! If you get a sudden spike in traffic that pushes you over bandwidth or storage limits, you’ll start accruing small charges. It’s rare for personal projects, but it’s worth monitoring.

At the end of the day, switching to Blaze is a smart move for personal projects that need more than 100 concurrent connections. It’s official, allowed, and won’t cost you a penny if you stay within the free tier.
