Everything You Need to
Secure Your Code

FluxCipher combines AI intelligence with battle-tested cryptography to deliver a security layer that adapts to your codebase.

AI-Adaptive Obfuscation
Our neural engine learns your code patterns and applies context-aware obfuscation that maximally protects logic while preserving runtime performance. No two outputs are alike.
AES-256 Source Encryption
Military-grade AES-256 encryption applied at the source level. Your intellectual property is protected with the same standard used by the NSA for top-secret data classification.
Real-Time Threat Detection
AI-powered monitoring continuously scans for decompilation attempts, unauthorized access patterns, and reverse engineering signals — alerting you instantly via Slack, email, or webhook.
Multi-Language Support
Supports JavaScript, TypeScript, Python, Java, C#, Go, Rust, PHP, Ruby, and more. Our language-aware engine understands syntax trees to apply encryption that won't break your build.
CI/CD Pipeline Integration
Drop-in GitHub Actions, GitLab CI, Jenkins, and Bitbucket Pipelines support. Encrypt on every commit, tag, or release automatically — zero friction, zero manual steps.
License & Access Control
Bind encrypted code to specific machines, users, or time windows. Generate tamper-proof license keys that control who can run your software and for how long.
Audit Logs & Compliance
Full audit trails for SOC 2, ISO 27001, and GDPR compliance. Every encryption event, key rotation, and access attempt is immutably logged and exportable.
Zero-Latency Runtime
Our encrypted runtime decrypts at microsecond speed using hardware-accelerated AES-NI instructions. Benchmarks show less than 0.3% overhead versus unencrypted execution.
Process

Secure in Minutes, Not Months

FluxCipher integrates seamlessly into your existing workflow. Four simple steps from signup to shipping protected code.

Connect Your Repository
Link your GitHub, GitLab, or Bitbucket repository with one click. FluxCipher requests only the minimum permissions needed to read and process your code files.
Configure Encryption Rules
Use our visual dashboard or config-as-code to define which files, functions, or patterns to protect. Set obfuscation intensity, license policies, and alert thresholds.
AI Encrypts Automatically
On every push or on-demand, our AI engine processes your code, applies multi-layer encryption and obfuscation, runs validation tests, and outputs protected builds in seconds.
Ship with Confidence
Deploy your protected artifacts as usual. FluxCipher's runtime module handles secure decryption transparently, while the monitoring dashboard tracks threats around the clock.
Our Mission

Built by Developers,
For Developers

We started FluxCipher after watching a competitor steal our startup's core algorithm through reverse engineering. We vowed to build the protection we wished had existed.

  • Backed by $8.4M seed round from Sequoia and Andreessen Horowitz
  • SOC 2 Type II certified and GDPR/CCPA compliant infrastructure
  • Processing over 2.8 million code files encrypted per month
  • Headquartered in San Francisco with a fully distributed team of 34

Don't take our word for it. Here's what engineers building with FluxCipher have to say.

★★★★★

"We distribute a SaaS desktop agent to enterprise clients and always worried about competitors reverse engineering our ML models embedded in it. FluxCipher's AI obfuscation made our code completely unreadable. It dropped into our GitHub Actions pipeline in under 20 minutes."

DL
Daniel Larsson
Lead Engineer, Prismatic AI
★★★★★

"We sell proprietary trading algorithms to hedge funds. One of our clients' copies got leaked and reverse engineered — it cost us seven figures. After switching to FluxCipher, we haven't had a single incident in 18 months. The license binding feature is an absolute game-changer."

SR
Samantha Royce
CTO, Quantex Systems
★★★★★

"I was skeptical — every 'code protection' tool I'd tried before either broke the build or added unbearable overhead. FluxCipher is legitimately different. The zero-latency claim is real. Our Node.js API added 0.2ms per request max. The audit log alone satisfies our SOC 2 auditors."

FAQ

Frequently Asked Questions

Everything you need to know about FluxCipher's security platform.

Does FluxCipher ever store my source code on your servers?
+
No. FluxCipher processes your code in ephemeral, encrypted compute containers that are destroyed immediately after each job completes. We operate a zero-persistence model — your source code is never written to disk on our infrastructure. For Enterprise customers, we also offer a fully on-premise deployment where all processing happens within your own environment. Our architecture has been reviewed and audited by third-party penetration testers annually.
Will encryption break my application's runtime performance?
+
FluxCipher is designed for near-zero overhead. Our runtime decryption module uses AES-NI hardware acceleration, which is available on virtually all modern CPUs (Intel 2010+, AMD 2011+). In our benchmark suite of 200+ real-world applications, the average runtime overhead was 0.27%. For JavaScript applications, our engine generates highly optimized obfuscated code that V8 can JIT-compile efficiently. We provide a performance report with every encryption job so you can see the exact impact before shipping.
Which programming languages does FluxCipher support?
+
FluxCipher currently supports full encryption and obfuscation for JavaScript, TypeScript, Python, Java, C#, Go, Rust, PHP, Ruby, and Kotlin. We provide basic obfuscation for C, C++, Swift, and Dart. Our language support roadmap includes Scala, Elixir, and Haskell in Q2 2025. Enterprise customers can request custom language parser development. We use AST-level analysis for all supported languages, meaning we understand your code structure — not just text — enabling safer and more thorough protection.
How does the license binding feature work exactly?
+
License binding allows you to tie your encrypted code to specific execution environments using cryptographic fingerprinting. You can bind to: hardware identifiers (CPU ID, MAC address, disk serial), user accounts, IP address ranges, or time windows (expiring licenses). When your encrypted application starts, the FluxCipher runtime module verifies the environment fingerprint against a signed license token. If the check fails, the decryption key is never released. Licenses can be issued, revoked, and audited from your FluxCipher dashboard or via our REST API. This works offline too — licenses can be validated without phoning home.
What happens if FluxCipher shuts down — can I still run my software?
+
This is one of our most common questions and we take it seriously. When you encrypt code with FluxCipher, the resulting encrypted artifacts and the runtime decryption module are entirely self-contained. The runtime module does NOT require any connection to FluxCipher servers to decrypt and run your code — it uses keys embedded in the artifact at encryption time. If you use license binding with online validation, we provide an "offline grace period" option of 30–90 days. Additionally, Professional and Enterprise customers receive a full cryptographic key escrow export that lets you build a self-hosted fallback runtime. We also maintain a legal continuity fund that would keep the key infrastructure operational for 5 years in a wind-down scenario.
Is FluxCipher compliant with SOC 2, GDPR, and CCPA?
+
Yes. FluxCipher holds a SOC 2 Type II certification covering Security, Availability, and Confidentiality trust service criteria. Our most recent audit was completed in October 2024 by Schellman & Company LLC. For GDPR compliance, we act as a data processor and maintain a Data Processing Agreement (DPA) available for all customers. We support the right to erasure, data portability, and maintain a GDPR-compliant subprocessor list. For CCPA, we support consumer data deletion requests and do not sell personal data. Compliance documentation packages are available to Enterprise customers for their own audit requirements.
Can I try FluxCipher before committing to a paid plan?
+
Absolutely. All plans include a 14-day free trial with full access to all features of the selected tier — no credit card required to start. After the trial, if you choose not to subscribe, your account downgrades to a free tier that allows encryption of up to 1,000 lines per month across 1 repository (JavaScript only). We also offer a free sandbox environment where you can test our API and CI/CD integration without connecting a real repository. For Enterprise evaluations, we offer a dedicated 30-day proof-of-concept engagement with a dedicated solutions engineer assigned to your team.
