RepDB
Patchlog is a drop-in changelog for web apps. You embed one script tag, with no SDK and no npm install, and get an in-app "what's new" widget plus a hosted changelog page and an RSS feed.
The widget renders inside a Shadow DOM, so it never inherits or leaks the host page's CSS, and it behaves the same in React, Vue, Rails or plain HTML.
Other features: scheduled publishing so you can write updates ahead of time and have them post themselves, per-update view and click analytics, light/dark/auto theming with a custom accent colour on Pro, and 2FA on accounts.
Pricing is flat rather than metered on your traffic: free for 1 project and 25 updates, which shows a small "Powered by Patchlog" badge, or $7/month ($60/year) for unlimited projects and updates, badge removal and advanced analytics. Most tools in this category bill per monthly active user, so the bill grows with your app even though writing release notes does not get harder.
What Patchlog does not do: no user segmentation or targeting, no NPS surveys, no roadmaps or feature voting boards, no email digests, and no public API. If you need those, Beamer or Canny is the better fit.
RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps โ not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.
A free tier includes 400 exercises with flat-style 512ร512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings โ exclusive to that tier.
Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.
Patchlog RepDBPatchlog's answer
A real free plan with no trial expiry, and a widget that embeds in any web app with two lines of JavaScript. No bloated feature set, no enterprise pricing for a tool that should be simple.
RepDB's answer:
RepDB is sold as a one-time download, not a metered API โ you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.
Patchlog's answer
Most changelog tools charge $29-$60/month for features most small teams never use. Patchlog gives you a working in-app widget, a public SEO-friendly changelog page, full Markdown support, and RSS on the free plan. The Pro plan is $5/month. It covers everything 90% of SaaS products actually need.
RepDB's answer:
Most alternatives are subscription APIs โ you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.
Patchlog's answer
Indie founders, solo developers, and small SaaS teams who want to keep users informed about product updates without paying enterprise prices for it.
RepDB's answer:
Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.
Patchlog's answer
Built out of frustration with the existing options. Every changelog tool was either too expensive, too complex, or offered a "free trial" that expired before you could evaluate it properly. Patchlog started as the tool we wished existed: simple to embed, honest free tier, no fluff.
RepDB's answer:
RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

This is exactly how I built the changelog widget for Patchlog. It is a drop-in "what's new" widget for SaaS products: one script tag, rendered inside a Shadow DOM so it never collides with the host site's CSS, with light, dark, and auto theming that reads the host's CSS variables when you want it to. There is a free tier if you want to see the technique in a shipped product rather than a blog snippet. - Source: dev.to / 22 days ago
I build Patchlog, so the snippet above is my own tool. I'm not going to pretend otherwise. It's early: the free tier is one project and 25 updates, which is genuinely what I run on my own projects. I'm sharing the approach because it's helped me, and if it saves you the afternoon it cost me to think through, great. - Source: dev.to / 23 days ago
