Features and specs

What each product offers, as listed by its team.

Project Euler 6 features
FlashFX 14 features
  • Problem-Solving Skills
    Project Euler offers a range of problems that can help enhance your mathematical and algorithmic problem-solving abilities.
  • Programming Practice
    It provides an excellent platform to practice and improve your programming skills across multiple languages.
  • Mathematical Insight
    Many problems require a deep understanding of mathematical concepts, thus helping users to gain and apply advanced mathematical knowledge.
  • Community
    Project Euler has a vibrant community where you can discuss problems and solutions with like-minded individuals.
  • Free Access
    All the problems and resources on Project Euler are freely accessible, making it an affordable way to learn.
  • Self-Paced Learning
    Users can progress at their own pace, making it suitable for learners of all levels.

Possible disadvantages

  • Steep Learning Curve
    The problems can become very challenging quickly, which might be discouraging for beginners.
  • Limited Step-by-Step Guidance
    There is little to no step-by-step guidance or hints available, which might hinder the learning process for some users.
  • Focus on Mathematics
    The heavy focus on mathematical problems may not appeal to those primarily interested in practical programming tasks.
  • Lack of Immediate Feedback
    The platform does not offer immediate feedback on code submissions, which might slow down the learning process.
  • No Built-in IDE
    Users need to use their own development environments, which might be inconvenient for some, especially beginners.
  • Keyframe Interpolation
    Create keyframes across any property and control interpolation with professional presets and custom bezier handles, giving you precise control over how animations ease in, ease out, or follow custom motion curves between states.
  • Timeline Editor
    A multi-layer timeline lets you organize, sequence, and fine-tune every element in your composition. Stack layers, trim durations, and scrub through your animation in real time, just like professional tools such as After Effects.
  • Scene Graph Architecture
    Organize your composition using a fully hierarchical scene graph. Group elements, nest compositions, and apply transformations that cascade through parent-child relationships, keeping complex animations clean and manageable.
  • Effects and Blend Modes
    Apply a full suite of visual effects and blend modes to any layer in your composition, enabling rich, composited looks straight in the browser without needing to export to a separate tool for post-processing.
  • .ffx File Format
    Projects are saved in .ffx, a custom binary format built to replace Lottie JSON. It offers smaller file sizes, faster load times, and higher fidelity, making it better suited for complex, professional-grade animations.
  • Asset Marketplace
    Browse, share, and sell templates, presets, and animation components through the built-in FlashFX marketplace. Creators can monetize their work while users speed up their workflow with ready-made, customizable assets.
  • Audio-Driven Animation
    Import an audio track and let FlashFX automatically generate animation keyframes driven by sound amplitude, frequency bands, or beat detection. Sync visual motion to music or voiceover without manually placing a single keyframe.
  • Mask System
    Apply masks to any layer using shapes, paths, or inverted selections. Combine multiple masks with add, subtract, and intersect modes to reveal, hide, or isolate parts of a layer with pixel-level precision.
  • Motion Paths
    Visualize and edit the spatial trajectory of any animated element directly on the canvas. Drag path handles to reshape movement, add curve points, and create flowing, organic motion that goes far beyond simple A-to-B transitions.
  • Text Animation
    Animate text at the character, word, or line level with dedicated text animators. Control tracking, opacity, position, and rotation per-character to create kinetic typography effects common in professional broadcast and social content.
  • Vector Shape Tools
    Draw and edit vector shapes directly on the canvas with a built-in pen and shape tool suite. Animate stroke, fill, path morphing, and trim paths to create clean, resolution-independent motion graphics from scratch.
  • Real-Time Preview
    Preview your animation at full quality directly in the browser without rendering. Scrub, play, and loop any section of your timeline instantly, keeping your creative flow uninterrupted during the editing process.
  • Export Engine
    Export finished animations as MP4, WebM, GIF, or Lottie JSON for web embedding. Choose resolution, frame rate, and compression settings to optimize output for social media, web, app UI, or client delivery.
  • Preset Animation Library
    Access a built-in library of animation presets for common effects like fade-ins, bounces, slides, and reveals. Apply any preset to a layer in one click and customize it further, dramatically speeding up repetitive animation tasks.

Questions & Answers

As answered by people managing Project Euler and FlashFX.

What makes your product unique?

FlashFX's answer:

FlashFX runs entirely in the browser with no installation, no plugins, and no OS dependency. It combines a professional-grade timeline, 3D rendering, expressions, and a marketplace in one tool, at a fraction of After Effects' cost. The custom .ffx format and neural-network-driven animation features push it beyond a simple web clone into genuinely new territory.

Why should a person choose your product over its competitors?

FlashFX's answer:

FlashFX removes every barrier that makes After Effects inaccessible: price, installation, hardware requirements, and a steep learning curve. It delivers comparable core features in a browser tab, with a cleaner interface, a built-in asset marketplace, and a pricing model that doesn't lock professionals and beginners into the same expensive subscription.

How would you describe the primary audience of your product?

FlashFX's answer:

The primary audience is motion designers, content creators, and UI/UX designers who need professional animation tools but are priced out of or intimidated by Adobe's ecosystem. This includes freelancers, indie studios, social media creators, and developers building animated assets for web and app interfaces.

What's the story behind your product?

FlashFX's answer:

FlashFX started as a personal project built out of frustration with the existing landscape of animation tools. After Effects is powerful but expensive, complex, and desktop-only. Browser-based alternatives were either too simple or poorly engineered. Over roughly two years and four complete rebuilds, FlashFX evolved from a rough prototype into a two-product suite with over 15,000 users, a 3,400-member Discord community, and a growing waitlist, all without any paid marketing. Each rebuild wasn't failure, it was refinement, progressively closing the gap between what the web could do and what professionals actually needed. The decision to go browser-native, use a custom binary format, and invest in 3D rendering were all unconventional bets that paid off through traction, not theory.

Which are the primary technologies used for building your product?

FlashFX's answer:

FlashFX is built in TypeScript and React for the editor layer, Three.js for 3D rendering, and a custom binary format (.ffx) for project files. Animation tooling draws influence from Theatre.js. Neural network research using Sprecher Networks powers audio-driven animation and motion curve learning features.

Who are some of the biggest customers of your product?

FlashFX's answer:

FlashFX is currently pre-revenue, so there are no paying customers yet. However, the platform has 1,200 active beta users and 2,000 waitlist sign-ups, all acquired organically, which signals strong demand ahead of any formal commercial launch.
