What is HeyForm?

HeyForm's v3 has been in release candidates for months, now moving mostly on community fixes.

HeyForm has been on v3.0.0 release candidates since at least March 2026, and the recent cuts are small: Italian and Brazilian Portuguese localization, an IPv6 bypass fix in the outbound SSRF guard, and plain-text rendering of group page titles. Most recent changes come from first-time contributors.

What is Sleeknote?

Sleeknote embedded an AI campaign advisor and added single-click answer collection to its popup toolkit.

Sleeknote shipped two significant features in quick succession: Answer Buttons, which let visitors respond to popup questions with a single click (synced directly to connected email platforms), and Sidenote, an AI chat agent embedded in the dashboard that answers questions about campaign performance and suggests next steps using the user's own data. Earlier in the year, Learn to Earn launched a new campaign type where visitors complete short educational modules to unlock a discount — a behavioral model meaningfully different from standard lead capture.

HeyForm vs Sleeknote: editorial side-by-side

0.0

HeyForm's v3 has been in release candidates for months, now moving mostly on community fixes.

◆ Current state

HeyForm has been on v3.0.0 release candidates since at least March 2026, and the recent cuts are small: Italian and Brazilian Portuguese localization, an IPv6 bypass fix in the outbound SSRF guard, and plain-text rendering of group page titles. Most recent changes come from first-time contributors.

◆ Where it's heading

The v3 line is in a long stabilization phase with localization and security patches rather than new form features. Releases have slowed to roughly one every three to six weeks, and nothing has shipped since mid-July.

◆ Prediction

The entries do not show what is blocking a v3.0.0 final; the next release is more likely another RC with community fixes than a stable cut.

6.3

Sleeknote embedded an AI campaign advisor and added single-click answer collection to its popup toolkit.

◆ Current state

Sleeknote shipped two significant features in quick succession: Answer Buttons, which let visitors respond to popup questions with a single click (synced directly to connected email platforms), and Sidenote, an AI chat agent embedded in the dashboard that answers questions about campaign performance and suggests next steps using the user's own data. Earlier in the year, Learn to Earn launched a new campaign type where visitors complete short educational modules to unlock a discount — a behavioral model meaningfully different from standard lead capture.

◆ Where it's heading

Sleeknote is expanding beyond static popups toward a multi-channel engagement platform: web push (March), AI advisors (Sidenote), educational gates (Learn to Earn), and now single-click data collection (Answer Buttons). Each addition raises the floor for what a 'popup tool' is expected to do, and Sidenote in particular signals a move toward AI-assisted campaign management rather than manual optimization. The Scandinavian market focus — Danish-language content, Rule.io integration — is a secondary but consistent signal.

◆ Prediction

Sidenote will expand from advisory into execution — suggesting and then launching campaign variants or adjusting targeting directly. Answer Buttons will likely gain follow-up branching logic to support conditional popup flows based on the answer given.
