hasl.ink vs Bio.fm
Free vs free — but only one has AI.
Bio.fm is a free link-in-bio tool with clean themes, simple analytics, and a no-nonsense vibe. It works. If your bar is "a page that lists my links," Bio.fm clears it. But hasl.ink clears a much higher bar at the same price: GPT-4 chat that answers visitors as you, an AI design studio that generates themes from a prompt, a full analytics dashboard with device and referrer breakdowns, and a brutalist monospace aesthetic that actually stands out. Same price ($0). Different ceiling.

The full picture
Bio.fm is a fine free link-in-bio. The page loads, the links work, the themes are inoffensive. For a casual user who just needs to point Instagram at something, it's enough. There's no real cost to using it and no real friction.
The problem is the ceiling. Bio.fm is a 2020-era product in a 2026 market. There's no AI chat for visitors. There's no AI design assistant. The analytics are basic — you get clicks and views, but not the device, browser, OS, and referrer breakdowns that actually tell you who your audience is. The themes look like every other link-in-bio page, which is to say generic.
hasl.ink does all the same baseline stuff — drag-and-drop links, social platforms, click tracking — and then adds the layer Bio.fm doesn't have. The AI chat is the real differentiator: visitors hit your page, ask "what services do you offer?" or "where can I book a call?", and the AI answers in your voice based on your profile and uploaded knowledge base. That's a feature no other free link-in-bio tool ships in 2026.
The design studio is the second gap. Bio.fm gives you a theme picker. hasl.ink gives you a prompt-based AI theme generator backed by a full design studio. You can pick a preset (Dark Mode, Light Mode, Neon, Pastel, etc.) and then tune every variable — background style, container width, profile size and shape, link variant (solid, outlined, glass, gradient, neumorphic), hover effects, social link style. WCAG contrast checks run automatically.
Analytics are the third gap. hasl.ink ships a full dashboard: time-series chart with multiple granularities (5-minute, hourly, daily), CTR, top-performing links, top referrers, and breakdowns by device, browser, and OS. Bio.fm shows you basic counts.
Where Bio.fm wins: nothing meaningful, given they're both free. Bio.fm has been around longer, so if "established product" matters to you, that's one tick in its favor.
Is hasl.ink really free? Yes — free during beta. The pricing page is clear: it may become paid in the future if server costs grow, but currently every feature is free.
Does Bio.fm have AI features? No. Bio.fm has no visitor-facing AI chat and no AI design assistant. hasl.ink is the only free link-in-bio tool shipping both.
Can I switch from Bio.fm to hasl.ink quickly? Yes. Setup is about 2 minutes. Drop in your links, pick a theme (or generate one with AI), and you're live at hasl.ink/yourusername.
Are hasl.ink analytics actually free or is there a paywall? Fully free. Clicks, views, devices, browsers, OS, referrers, time-series charts — no paid tier gating analytics during beta.

Verdict.
Bio.fm is a perfectly fine free link page. hasl.ink is a free link page plus AI chat, AI design studio, and proper analytics. Same price, different product. For 2026, hasl.ink is the obvious pick unless you specifically prefer the softer Bio.fm aesthetic.
