An honest, side-by-side feature comparison with TinyMCE 7, CKEditor 5, Froala 5, and TipTap 2 — the four editors you're most likely shortlisting us against in a buying decision. All data verified from vendor documentation and changelogs as of April 2026.
At v2.0, RichTextBox ships the full collaboration + review + AI stack (track changes, comments, revision history, mentions, slash commands, AI Toolkit, streaming providers, Yjs presence) — matching TinyMCE 7 and CKEditor 5 on everything except real-time cooperative text editing.
Perpetual, one-time license. No per-user fees, no usage metering, no premium plugin tiers. Compare to TinyMCE (subscription + AI credits), CKEditor (subscription + separate AI + Collab SKUs), TipTap (document-based subscription), Froala (per-project commercial).
ASP.NET Core first-class. Drop-in <richtextbox> Razor Tag Helper, PHP / JSP / Node / Classic ASP wrappers included. Headless editors (TipTap / Lexical) require you to build the server story yourself.

No single editor wins every bake-off. Here's a candid take on where each competitor is strongest, and when we'd recommend them over us.
You're on .NET / ASP.NET Core (or PHP / JSP / Classic ASP) and want the editor integrated at the server layer, not bolted on via a JS bundle. You want the full collaboration + AI stack in a single perpetual license without stitching together three subscription SKUs. Your buying committee dislikes usage-metered SaaS. You're comfortable operating your own infrastructure; you don't need a vendor-hosted cloud.
You want a vendor-hosted AI with a ready billing meter (they'll invoice AI usage for you). You're already paying for Tiny Cloud collaboration and don't want to migrate. You have a Node-only stack and a React/Vue frontend that handles its own server integration.
You need the most mature real-time cooperative text editing available today (proprietary OT with on-prem server option) and you're willing to pay the price of admission. Your buyers specifically require a published WCAG 2.2 AA audit artifact in the RFP. Your paste-from-Word fidelity requirements are extreme.
You're building a Notion-style product and you need a headless editor built on ProseMirror schemas that you can extend aggressively. Your team is comfortable operating Yjs + Hocuspocus for collab. You want the largest open-source extension ecosystem and you don't need a server-side wrapper.
You want the simplest drop-in JS editor with decent defaults and the lowest time-to-demo. You don't need collaboration (track changes, comments) out of the box. You're on a non-.NET stack and don't need server-side wrappers.
You want free and open source. You have the engineering bandwidth to build your own collab, review, and AI layers. You specifically want Meta-grade a11y + performance (Lexical) or a schema-driven substrate (ProseMirror). You're not shipping to a buying committee that asks for enterprise features.
Honesty check
Good comparison pages tell the truth about their gaps. Here's ours:
y-prosemirror-style text binding.Every feature in the matrix has a live demo. No API key required for the AI surfaces — the built-in resolver runs in demo mode so you can click every button end-to-end before downloading.
