Reflag (formerly Bucket) Review (2026)

A deliberately narrow feature-flag tool built for B2B SaaS on TypeScript, with native feature entitlements instead of A/B experiments. Small, freshly rebranded, and focused - which is both the appeal and the risk.

What Reflag actually is

First, the name. Reflag is the tool that used to be called Bucket. It rebranded on 4 September 2025, and bucket.co now 301-redirects to reflag.com. Bucket started in 2021 as a feature-metrics and feedback product - the name referenced the “leaky bucket” of user drop-off - pivoted into feature management in June 2024, then became Reflag. Same company, current name. If you’ve read about Bucket anywhere, this is it.

Now the product. Reflag is feature flags purpose-built for B2B SaaS, on TypeScript. Its standout is native feature entitlements: you gate flags at the company or subscription level and map features to subscription tiers, not just to individual users. On top of that it does feature adoption metrics and user feedback. The whole thing is scoped tightly around one buyer - a B2B SaaS product team that needs per-account entitlements.

This is a narrow tool on purpose, and that’s the entire story - both the appeal and the risk.

The one thing it’s genuinely good at: entitlements

Most flag tools think per user. You roll a feature out to 10% of users, then 50%, then everyone. Reflag thinks per account. In B2B SaaS, the unit that matters is usually the customer company and the plan they’re on. Reflag lets you tie a feature to a subscription tier, so every account on that tier gets it, and gate access at the company level.

That maps directly onto how SaaS pricing and packaging actually works. If your real problem is “customers on the Growth plan should get this feature, customers on Starter shouldn’t,” a general flag tool makes you build that yourself. Reflag treats it as the core use case. It’s TypeScript-first, ships a toolbar and CLI, and has an MCP server for AI-assisted flagging - a modern, developer-friendly package for its niche.

Pricing: published and simple

Reflag lists its prices, and the quota unit is MTU - Monthly Tracked Users:

PlanPriceMTUsNotes
Starter$01,0003 environments, unlimited seats, no credit card
Pro$100/mo annual ($125 monthly)10,000Unlimited environments and seats, user permissions
EnterpriseCustomCustomMigration support, SAML

Extra MTUs on Pro run around $120 to $150/mo per additional 25,000. It’s clean, and there’s no sales wall to see the numbers - a welcome contrast to the enterprise vendors in this category. The pricing fits its audience: small enough teams that $100/mo is reasonable, scaling by tracked users rather than seats.

The gotcha: narrow scope plus early-stage risk

Here’s what to weigh honestly. Reflag’s focus is a strength for the right team and a hard limit for everyone else. If you’re not a B2B SaaS on the TypeScript stack, this isn’t your tool. There’s no A/B experimentation at all. There’s no self-hosting and no open-source option. And the full multi-language SDK breadth isn’t even published - it’s deliberately TypeScript and JavaScript centric, so if your backend is Go or Python or your app is native mobile, the coverage may not be there.

Then there’s company risk. Reflag is small - around $3.7M raised - and it just rebranded from Bucket in September 2025. That’s a small team with a thin public track record against well-funded incumbents. It has real customers, including GitBook, Pleo, and Code Climate, which is a good signal for a company its size. But betting a multi-year roadmap on it is a different risk profile than picking an established vendor.

Reflag versus the field

The honest framing: Reflag wins on B2B-SaaS entitlements and loses on breadth. Against LaunchDarkly or DevCycle, it’s cheaper, simpler, and far better at tying features to subscription tiers - but it does dramatically less, and it’s a fraction of the size. Against experimentation platforms like Optimizely or Statsig, it isn’t even in the same category, because it doesn’t do experiments. It’s not trying to.

Should you use it?

Use Reflag if you’re a B2B SaaS product or engineering team on TypeScript, you need per-account feature entitlements tied to subscription tiers, and you value a focused tool with published pricing over a broad platform.

Don’t use Reflag if you need A/B experimentation, you’re not on the TypeScript or JavaScript stack, you need broad multi-language SDKs, you require self-hosting, or a small, freshly rebranded vendor is more longevity risk than you want to carry.

Bottom line: Reflag does one job - B2B SaaS feature entitlements - and does it cleanly. For that exact team it’s a genuinely good fit and priced fairly. For anyone outside that niche, the missing experimentation, limited SDK breadth, and early-stage size make it the wrong tool. Match it to the job, and don’t stretch it past its scope.

Our Verdict

Reflag - the tool formerly called Bucket - does one thing on purpose. It's feature flags and native entitlements for B2B SaaS on TypeScript, letting you gate features at the company and subscription-tier level rather than just per user. For that exact job it's clean, transparent, and well designed. Outside it, the limits show fast, with no A/B experimentation, no self-hosting, and SDK breadth that isn't even published. Add early-stage risk - roughly $3.7M raised and a fresh rebrand in September 2025 - and this is a focused bet for a specific team, not a general-purpose flag platform.

Frequently Asked Questions

Is Reflag the same as Bucket?

Yes. Reflag is the tool that was called Bucket until 4 September 2025. bucket.co now 301-redirects to reflag.com. Bucket started in 2021 as a feature metrics and feedback product, pivoted into feature management in June 2024, then rebranded to Reflag. If you saw Bucket referenced anywhere, that's the same company under its current name.

How much does Reflag cost?

Reflag publishes its prices. Starter is $0 for 1,000 MTUs with 3 environments, unlimited seats, and no credit card. Pro is $100/mo billed annually or $125/mo monthly, for 10,000 MTUs with unlimited environments and seats, plus user permissions and self-cleaning flags. Enterprise is custom with migration support and SAML. The quota unit is MTU - Monthly Tracked Users. Extra MTUs on Pro cost around $120 to $150/mo per additional 25,000.

Does Reflag do A/B testing?

No. Reflag is not positioned as an experimentation platform. Its focus is feature flags, native entitlements, feature adoption metrics, and user feedback for B2B SaaS - not statistical A/B experiments. If you need experimentation, look at Optimizely, Statsig, or GrowthBook instead. This is a deliberate scoping choice, not an oversight.

Can you self-host Reflag?

No. Reflag is proprietary SaaS with no self-hosting or open-source offering. Its SDKs are TypeScript-first. If self-hosting is a requirement, Reflag is not a fit, and you'd want an open-source platform like Unleash or Flagsmith.

What are feature entitlements, and why does Reflag emphasize them?

Feature entitlements gate access at the company or subscription level rather than per user - you map a feature to a subscription tier so every account on that tier gets it automatically. That's exactly what B2B SaaS pricing and packaging needs, and it's Reflag's core differentiator. Most flag tools target per-user rollouts, so if your problem is tying features to plans, Reflag is built for it in a way general flag tools aren't.
