Herald vs Olvy
Herald and Olvy both help software teams tell users what shipped, but they approach the job differently. Herald is a GitHub-native changelog tool: its AI reads merged pull requests (or branch and release-to-release diffs) and drafts the release, which publishes to a hosted changelog page, embeddable widget, email subscribers — and back to GitHub Releases. Olvy is an AI-powered user-feedback platform (now owned by Amoeboids) where changelogs and release notes are one module of a broader feedback-analysis suite. Here's how the two compare on features, pricing, and fit — and where each falls short.

What is Herald?
Herald automates the changelog the same way engineers ship: from the repository. Connect a GitHub repo and its AI reads merged pull requests — titles, descriptions, and labels, or a branch or release-to-release diff — and drafts a clean, human-readable release entry you edit or publish as-is. Entries go to a hosted public changelog page, a fast embeddable widget, and email subscribers, and the integration is bidirectional: Herald can publish the finished release back to GitHub Releases, so the repo and the changelog stay one source of truth.
The Team plan adds the operational depth — private repos with gated changelogs (share links, JWT, or admin access), multi-repo aggregation through a parent/child project rollup, audience segmentation, custom domains, and outgoing webhooks. The scope stays deliberately narrow: it's a changelog pipeline, not a product-communication suite — no feedback boards, roadmap, in-app notifications, Slack publishing, or social posting.
Pricing: Herald prices per workspace, not per user. Solo is $16/month billed annually ($190/year) with 1 project, 1 repository, and 1 seat. Team is $66/month billed annually ($790/year) — about $79 month-to-month — with 5 projects and 5 seats, private repos, gated changelogs, custom domain, full analytics, and +$50/month expansion packs for 5 more projects and seats. Studio is $208/month billed annually ($2,490/year) with unlimited projects and seats plus full white-label. There's a 14-day full-featured trial with no credit card, but no permanent free plan.
Where Herald shines
- AI drafts releases from merged PRs, branch diffs, or release-to-release diffs — not from a blank editor
- Bidirectional GitHub integration: publishes finished releases back to GitHub Releases
- Multi-repo changelogs via parent/child project rollup on Team
- Private repos and gated changelogs (share link, JWT, or admin access)
- Workspace pricing, not per-user or per-MAU — Team is 5 seats and 5 projects for $66/month annual
Where Herald falls short
- Changelog only — no social posts, blog posts, newsletters, or other content formats
- No Slack publishing, feedback boards, roadmap, in-app notifications, or NPS
- Solo plan is tightly boxed: 1 project, 1 repo, 1 seat, basic view counts, no private repos
- No permanent free plan — a 14-day trial, then paid
- A young indie product without the ecosystem or track record of decade-old incumbents
What is Olvy?
Olvy leads with feedback: a unified inbox that pulls user feedback from Slack, Discord, X, Telegram, the Play Store, Zendesk, Intercom, and email, then applies AI for sentiment, thematic analysis, auto-categorization, and summaries — plus 'Ask Olvy' conversational querying. The changelog side gives you a hosted release-notes page on a custom domain, in-app widgets, scheduled releases, per-release analytics, and automated release emails on the Business plan.
Its AI release writer generates copy from context you type or from linked resolved issues — there's no git or GitHub pipeline, and no social auto-posting (X appears only as a feedback source). After a near-shutdown in late 2024, Olvy was acquired by Amoeboids in early 2025 and is actively maintained, with the roadmap tilting further toward feedback, NPS, and surveys.
Pricing: Olvy's free plan covers one builder, unlimited release notes, and feedback analysis on up to 25 items. Essentials is $60/month for one builder, but integrations cost an extra $20/month each and extra builders $25/month. Business is $240/month with 5 builders, 10,000 feedback items, unlimited integrations, changelog email subscriptions, and API access, with a custom Enterprise tier above.
Where Olvy shines
- Deep AI feedback analysis: sentiment, themes, auto-categorization, summaries, and conversational querying
- Feedback ingestion from many sources — Slack, Discord, X, Telegram, Play Store, Zendesk, Intercom
- Hosted changelog with custom domain, widgets, scheduling, and per-release analytics
- AI release writer with tone controls and a Content Guide for consistent voice
- Free plan includes unlimited release notes
Where Olvy falls short
- No generation from git commits or GitHub activity — AI writes from typed context or linked issues
- No social auto-posting; X is a feedback source, not a publishing channel
- Integrations cost $20/month each below the $240/month Business plan
- Changelog email subscriptions and API access are gated to Business
- Feedback-first roadmap — the changelog is a secondary module, and the product was nearly sunset before its 2025 acquisition by Amoeboids
Which should you choose?
Choose Herald if you want an affordable GitHub-native changelog pipeline — AI drafts from merged PRs, published to a hosted page, widget, and email, with GitHub Releases kept in sync — and the changelog is the only channel you need. Choose Olvy if your bigger problem is feedback overload — collecting it from Slack, Discord, app stores, and support tools and having AI find the themes — and release notes are the closing step. And if the real bottleneck is writing the updates at all, consider Shipstar — it drafts changelogs, release notes, social posts, and newsletters straight from your GitHub activity and publishes them from one approval, starting free.
Or skip the writing entirely with Shipstar
Both Herald and Olvy still expect someone to sit down and write each update. Shipstar starts one step earlier: it connects to your GitHub repositories, reads what actually shipped, and drafts the changelog, release notes, social posts, and newsletter for you. You review and approve — Shipstar publishes to your changelog page, email subscribers, Slack, X, and LinkedIn from one approval.
It starts free (no credit card), and the Solo plan is Solo from $20/mo — a fraction of what most product communication platforms charge.
