A LaunchDarkly Alternative With Pricing You Can Predict
Featureflow gives you the feature-flag workflow your team actually uses - targeting rules, percentage rollouts, environments, and SDKs for your whole stack - for one flat monthly price with unlimited seats. No per-seat, per-MAU, or per-connection charges. No bill that grows because your product did. And a built-in LaunchDarkly importer brings your flags across in an afternoon. Running in production for 10+ years, serving 20M+ flag evaluations a day.
LaunchDarkly is a mature, capable platform - and for many teams, far more platform than they use, at a price that scales with seats and usage. Featureflow covers the workflow teams actually rely on, at one flat monthly price with unlimited seats - the bill is the same whether five people use flags or five hundred. The only metered number is SDK requests, and the allowances are generous enough that most teams never think about them.
Why teams go looking for an alternative
Almost nobody leaves LaunchDarkly over missing features. Teams leave over the bill and its unpredictability. Published LaunchDarkly pricing combines per-seat charges with usage-based charges that scale with client-side monthly active users and connections - so a successful product launch, a traffic spike, or simply adding services can change what you pay. Budgeting requires a spreadsheet; renewals bring surprises.
Featureflow bills one way: a flat monthly price with unlimited seats. Team is $99/month, Business is $399/month, and both include unlimited feature flags, projects, and environments. The only metered number is SDK requests - the HTTP calls your SDKs make to Featureflow - with allowances generous enough that most teams never approach them: 10M a month on Team, 100M on Business. And an allowance is a fair-use guideline, not a tripwire: passing it never cuts a flag off and never triggers a surprise charge. Invite your whole company; the bill doesn't move.
The second driver is plan gating. Across the industry, the features that make flags safe to run at scale tend to be reserved for custom-priced enterprise contracts. Featureflow keeps them on published, self-serve plans: audit trails, role-based permissions, and Google SSO are on every plan, including Free, and release pipelines with approval workflows are on Business at a flat $399/month - a price you can read on the pricing page, not negotiate on a call.

How far do the allowances go?
SDK requests are the HTTP calls your SDKs make to Featureflow - config polls, client-side flag fetches, and analytics batches. Server SDKs evaluate flags in memory, so your own traffic never touches the meter. Drag the sliders to see what your fleet would actually use:
Node.js, Java, Go, Python, Ruby, .NET processes
JavaScript, React, React Native clients
Estimate only. Assumes each server SDK instance makes one config poll and one summarised analytics batch per minute (~86K requests/month — the poll interval is configurable, so this scales down too), and each web or mobile session makes ~2 requests: one edge-cached flag fetch plus one analytics batch. Server SDKs evaluate flags in memory, so your own traffic volume never touches the meter. Ceilings are fair-use guidelines — passing one never cuts a flag off.
Everything you actually use, covered
Feature-flag platforms win comparisons with 200-row feature matrices; teams use about ten of those rows. Here is what Featureflow gives you - the ten rows that matter:
On/off flags plus any number of variants for experiments and staged variants.
Match on any user attribute - plan, country, role, account ID - with reusable segments across flags.
Deterministic bucketing by user ID: ramp 1% → 10% → 50% → 100% with a consistent experience per user.
Independent rules per environment - test targeting in staging before production.
Model your rollout stages and require approvals before a flag changes in production - included on Business at a flat $399/month, not a custom enterprise contract.
Rule changes stream to connected SDKs in seconds - no redeploy, no restart.
Who changed what, where, and when - on every plan, including Free, with retention stepping up by tier.
Single sign-on with Google for every team from day one; SAML available on request for Enterprise.
Connect a read-only access token, review exactly what will be created, then import your projects, environments, flags, targeting rules, and segments.
Java, Node.js, Go, Python, Ruby, .NET, JavaScript, React, React Native - plus a REST API.
Browsers and mobile receive pre-evaluated, CDN-cached flag payloads - small, fast, globally edge-served, with your targeting rules never exposed client-side.
First-class Jira app shows live flag status on your tickets; Slack keeps the team informed.
An official MCP server lets you create and manage flags from Claude and other AI assistants - something no major competitor ships today.
An honest note on where LaunchDarkly is ahead: if your team leans hard on its built-in experimentation analytics or its broader enterprise platform surface, evaluate those pieces carefully - Featureflow focuses on doing the release-management core exceptionally well rather than being an all-in-one suite. Many teams pair flags with the analytics tool they already have.
Client SDKs built for the edge
Client-side flag delivery is where SDK design shows. Featureflow client SDKs use smart partial evaluation: your targeting rules are evaluated server-side, and the browser or mobile app receives a compact, pre-evaluated payload - with only safe, time-based conditions deferred to the device. Because the payload contains results rather than rules, it's served from a global CDN with proper cache validation.
- Fast everywhere- flag payloads come from the nearest edge node, not a distant origin, so first paint isn't waiting on a flag round-trip.
- Nothing leaks - your targeting rules, segment definitions, and customer attributes never ship to the browser.
- Tiny and resilient - small payloads, local caching, real-time updates streamed in, and defined failover behaviour if the network is gone.
Migrating is an afternoon, not a quarter
The concepts map one-to-one - flags, variants, targeting rules, segments, environments - and the built-in importer does the recreation for you:
- Run the LaunchDarkly importer. Connect a read-only LaunchDarkly access token, review exactly what will be created, then import - projects, environments, flags, targeting rules, and segments come across in one pass. Flags whose targeting can't be mapped faithfully arrive disabled with a note, so nothing turns on unreviewed. Prefer scripting? Everything is also manageable through the Featureflow REST API.
- Swap the SDK. Initialise the Featureflow client with your environment key and update your evaluation calls - the shape of the code is nearly identical. SDKs cache rules locally and receive updates in real time, so behaviour under failure is safe by default.
- Run both, then cut over. Keep both SDKs live behind an environment variable for a day if you want belt-and-braces, then remove the old dependency.
Moving an established LaunchDarkly setup? Get in touch and mention you're coming from LaunchDarkly - our engineers will walk the import with you, review anything the importer flagged, and help with the SDK swap, so the cutover stays an afternoon.
The AI-native angle
Featureflow ships an official MCP server, so your team can create flags, flip rollouts, and inspect targeting straight from Claude or any MCP-capable AI assistant - "roll new-checkout to 25% in production" becomes a sentence, not a dashboard session. If your engineering workflow is increasingly agent-assisted, your feature flags can be too.
Frequently asked questions
Is Featureflow a drop-in replacement for LaunchDarkly?
For the core workflow most teams use - boolean and multivariate flags, user targeting rules, percentage rollouts, segments, environments, and audit trails - yes, the concepts map one-to-one. The built-in LaunchDarkly importer brings your projects, environments, flags, targeting rules, and segments across from a read-only access token; then you swap the SDK, and your evaluation calls look nearly identical. If you rely heavily on LaunchDarkly's experimentation analytics suite, evaluate that piece against your needs first.
How long does a migration actually take?
Most teams are running in an afternoon. The LaunchDarkly importer does the bulk of it: connect a read-only access token, review exactly what will be created, and import - flags whose targeting can't be mapped faithfully arrive disabled with a note, so nothing surprising turns on. The SDK swap is the mechanical part: initialise the client with your Featureflow key and update the evaluate calls. If you get stuck, contact us and we'll help.
Which SDKs does Featureflow provide?
Server-side SDKs for Java, Node.js, Go, Python, Ruby, and .NET; client-side SDKs for JavaScript, React, and React Native; plus a REST API for everything else and an MCP server so you can manage flags from AI assistants like Claude. All SDKs are included on every plan, including Free.
How is Featureflow priced compared to LaunchDarkly?
Featureflow is a flat monthly subscription with unlimited seats on every paid plan: Free, Team at $99/month, Business at $399/month, and custom Enterprise plans. The only metered number is SDK requests, with generous allowances - 1M a month on Free, 10M on Team, 100M on Business - and passing an allowance never cuts a flag off. There are no per-seat, per-MAU or per-connection charges. LaunchDarkly's published pricing combines per-seat charges with usage-based charges that scale with client-side MAUs, which is exactly the unpredictability many teams are trying to leave behind.
What happens if I go over my included SDK requests?
Nothing is cut off and there are no surprise overage charges. The allowance is a fair-use guideline: we email you a heads-up, and you can lower your SDK poll frequency, move up a tier, or optionally turn on auto-topup for prepaid extra requests. Your flags keep serving throughout.
Do I get audit trails, permissions, and SSO without an enterprise contract?
Yes. Audit trails, role-based permissions, and Google single sign-on are part of the product on every plan, including Free. Release pipelines and approval workflows are included on the Business plan at a flat $399/month - not locked behind a custom enterprise contract. SAML is available on request for Enterprise.
Is there a free plan?
Yes - free forever, no credit card required. It includes 5 seats, a project, two environments, unlimited feature flags, full targeting rules and progressive rollouts, 1M SDK requests a month, and access to every SDK. Every new account also starts with a 14-day full Business trial, and when it ends nothing is deleted - your flags keep serving on the Free plan.
Can I talk to a human before switching?
Yes - migration questions, security reviews, and pricing conversations go straight to the engineers who build the product, not a sales pipeline.
