Voiden is an offline, Git-native API client built around plain text files. Instead of storing requests in cloud workspaces or JSON collections, Voiden runs HTTP requests directly from Markdown files in your repository.
Requests, documentation, and tests live side-by-side in the same file and execute in place. Every part of a request โ endpoints, headers, auth, params โ can be structured and reused, making API work modular and version-controlled like code.
There are no exports, no sync steps, and no hidden storage layer. Git is the workspace. Markdown is the format. Your API requests are just files in your repo.
Voiden is designed for developers who already version control everything else โ and expect their API tooling to work the same way.
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 250 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.

RepDBRepDB'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.
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.
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.
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.

I've personally enjoyed following projects like Voiden. It's been interesting to see how quickly the project has evolved and how much the community has contributed. Recently they've even added support for AI agents like Claude and Codex through skills, which feels like a glimpse of where developer tools are heading next. - Source: dev.to / about 2 months ago
Great to see this space so active.I see this a TUI. You can also try out Voiden : https://voiden.md/ which has a different approach to this. Also YAML is a interesting choice - any reasons for this. - Source: Hacker News / 3 months ago
I think you will like https://voiden.md/ - some what similar to what you did here. - Source: Hacker News / 3 months ago
I too built something similar but as an API Client - https://voiden.md/ - Obsidian really picking up ! - Source: Hacker News / 3 months ago
This is very interesting - instead of curl you can integrate https://voiden.md/ maybe. - Source: Hacker News / 3 months ago
