About FeatureSignals

Enterprise-grade feature flags, without the enterprise lock-in

Built in Hyderabad by engineers who were tired of feature flag platforms that were too expensive, too slow, or too determined to own your stack.

Our Mission

To give every engineering team enterprise-grade feature flag management — without the enterprise price tag or lock-in

Feature flags are critical infrastructure. They control who sees what in production. They gate feature rollouts, power A/B experiments, and isolate risky code behind kill switches. They sit on the request hot path — every millisecond of evaluation latency multiplies across every user, every request, every day.

Yet the market for feature flag management has been dominated by platforms that treat this infrastructure as a profit centre — charging per-seat prices that grow with your team, locking you into proprietary SDKs, and making self-hosting an afterthought reserved for the highest enterprise tiers.

We believe feature flags should be fast, open, and affordable. Fast enough that you never think about them. Open enough that you can inspect, modify, and self-host them. And priced like infrastructure: predictable, transparent, and fair — regardless of how many engineers you hire.

Why FeatureSignals

What makes us different

Five things that set FeatureSignals apart from every other feature flag platform on the market.

Sub-millisecond evaluation

Our evaluation engine runs entirely in-memory with zero database calls on the hot path. Flag checks are served from a synchronised in-memory ruleset cache. The result: p99 latencies under 1ms. Your application code calls a flag, and the answer is back before the next CPU instruction matters.

OpenFeature-native, zero lock-in

FeatureSignals is built on the OpenFeature standard. All 8 language SDKs implement the OpenFeature provider interface. Your application code calls the OpenFeature API — not our proprietary one. If you ever decide to leave, you swap the provider, not your codebase. That is real portability.

Single Go binary, self-host in 3 minutes

No JVM. No Kubernetes requirement. No 12 microservices to orchestrate. The entire FeatureSignals server compiles to a single statically-linked Go binary. Self-host it on a €6/month VPS. Deploy it behind your firewall. Run it air-gapped. It is the same binary that powers our cloud.

AI Janitor for automated flag hygiene

Feature flags rot. Teams ship a flag, forget about it, and three years later it is still wrapping dead code in production. The AI Janitor scans your flags, identifies staleness, traces flag usage through your codebase, and suggests removals — or removes them automatically if you configure it to. Technical debt, deleted.

Flat pricing with unlimited seats

Pro is INR 1,999 per month — period. Unlimited team members, unlimited flags, unlimited environments. No per-seat calculus. No overage anxiety. No growth penalty. The bill you see is the bill you pay, every month. Enterprise adds SLAs, dedicated support, and self-hosting — quoted transparently, not negotiated against you.

Guiding Principles

What we stand for

The principles that guide every decision we make — from architecture to pricing, from hiring to support.

Performance as a feature

Sub-millisecond evaluation with no database calls on the hot path. An in-memory ruleset cache, a stateless eval engine, and relentless optimisation. Your users should never wait on a feature flag.

Open by default

Apache 2.0. Community Edition source is public. Self-host or cloud — your choice. Our roadmap is in the open. Our community shapes the product, not a pricing committee.

No vendor lock-in

OpenFeature-native across all 8 SDKs. Your application code depends on an open standard, not on us. Switching platforms is a configuration change — not a rewrite. Zero lock-in, by design.

AI as an accelerator

The AI Janitor finds stale flags, suggests cleanups, and automates flag hygiene — the kind of tedious maintenance that shipping teams hate. AI augments developers; it does not replace them.

Transparent, flat pricing

Flat rate with unlimited seats. INR 1,999/mo for Pro. No per-seat penalties, no surprise overage bills, no usage-based multipliers. Enterprise features are included — not nickel-and-dimed behind upgrade gates.

Built for engineers, by engineers

We are developers building tools for developers. Every design decision starts with: would we use this ourselves? Every API is designed for DX first. Every feature exists because we needed it.

Our Story

Built by engineers, for engineers — in Hyderabad

FeatureSignals started in 2025 with a real problem: our founding team needed feature flags for a production system serving millions of requests per day. The market options fell into two buckets — enterprise SaaS platforms that cost more than the rest of our infrastructure combined, or open-source projects that were too slow, under-maintained, or both.

The SaaS platforms were fast but their per-seat pricing meant our costs would scale linearly with every engineer we hired. The open source alternatives were free but added double-digit milliseconds of latency to every request — unacceptable for a performance-sensitive application.

There was no middle ground. So we built one — a single Go binary with sub-millisecond evaluation, an in-memory ruleset cache synchronised via PostgreSQL LISTEN/NOTIFY, 8 language SDKs implementing the OpenFeature standard, and an AI-powered janitor that finds stale flags before they become technical debt. Apache 2.0 licensed. Self-host or cloud. The platform we wished had existed when we needed it.

Our Values

The beliefs that shape every decision

Transparency

Open source code. Public roadmap. Honest pricing. We share what we are building, what it costs, and why. No dark patterns, no hidden fees, no bait-and-switch.

Craft

We sweat the details. Every millisecond of latency, every line of documentation, every API design choice. We believe great infrastructure software is craftsmanship, not assembly-line output.

Independence

Bootstrapped and self-funded. We answer to our users — not to VCs with growth-at-all-costs mandates. Our incentives are aligned with building a sustainable product, not chasing an exit.

Customer Success

Your success is our success. We ship features our customers ask for, not features our competitors have. Support is done by engineers who built the product, not by script-reading chatbots.

Remote-first, engineering-driven, based in India

We are a small, focused team of engineers passionate about developer tooling and infrastructure. Remote-first by design, with roots in Hyderabad, Telangana — India's startup capital. We believe great infrastructure software comes from teams that deeply understand the problem, not from the largest headcount or the most funding.

Open source is not a marketing tactic — it is how we build trust

The Community Edition of FeatureSignals is Apache 2.0 licensed. You can read every line of code, fork it, run it on your own hardware, and contribute back. The same binary that powers our cloud offering powers your self-hosted instance. No “open core” with a proprietary enterprise layer. No feature gating behind a license key for core functionality. Real open source, because trust is built on transparency.
