Feature-by-feature

AudioEye focuses on digital accessibility: it provides automated WCAG remediation, continuous scanning, manual expert audits, and integrations with CMS and developer tools (WordPress, Shopify, Jira, GitHub, Slack). It includes compliance reporting and overlay customization, but lacks hardware-level isolation. Fly.io is a deployment platform: it offers hardware-virtualized Fly Machines that launch instantly, Sprites sandboxes for safe AI code execution, zero-downtime deploys, autoscaling, and global regions (18). It provides fast NVMe storage, private networking, and a CLI that auto-generates containers for Rails, Django, Node, etc. While AudioEye integrates with many content and task management tools, Fly.io has no listed integrations beyond its own infrastructure. AudioEye targets legal and marketing teams; Fly.io targets developers building distributed systems or agents. Both have enterprise tiers, but AudioEye's pricing is per-month tiers, while Fly.io is consumption-based.

Pricing compared

AudioEye has tiered monthly pricing: Starter at $49/mo, Growth at $199/mo, Professional at $499/mo, and Enterprise custom. This is predictable for small to large businesses but can become expensive for multiple sites. Fly.io offers a free tier with limited usage (details not provided) and then usage-based pricing for compute, storage, and networking. This is more flexible for variable workloads but can be unpredictable. AudioEye's pricing is transparent upfront; Fly.io's requires estimation. For a small marketing site, AudioEye's $49/mo might be affordable, while Fly.io's free tier could suffice for a small app. For enterprise compliance, AudioEye's custom plans likely include manual audits; Fly.io's enterprise includes SSO and SOC2. Neither offers a pure free forever tier for unlimited use.
