Use Case Recommendations
Best for: imgproxy
imgproxy is a self-hosted image-processing server that resizes, crops, converts and optimises images on the fly, removing the need to pre-generate every variant an application might request. Processing options and the output format travel in the image URL, so a new size or format is a URL change rather than a pipeline job and a re-upload. It ships as Docker images and Linux packages and runs on essentially any host, and because it runs on your own infrastructure against your own storage, images never leave your environment and cost is your compute rather than a per-transformation bill — a distinction its published customer stories lean on heavily, one citing a roughly 90% cost reduction after moving off a SaaS processor. Security is handled in the core: real image dimensions are checked so image bombs are cancelled before decoding, URL signing prevents attackers generating arbitrary transformations as a denial-of-service vector, and header-based authorisation stops the caching layer being bypassed. The project is open-core. The open-source edition covers JPEG, PNG, GIF, WebP, AVIF and JPEG XL, resize, crop, rotate, watermark, filters, metadata stripping, PNG quantisation and basic smart cropping. Pro adds video, PDF and PSD preview generation, advanced watermarking and compression, GIF-to-MP4, SVG minification, object detection and SSIM-based auto-quality.
Ideal use cases:
- •Teams or individuals who need processing options encoded in the image url — a new variant is a url change, not a job
- •Teams or individuals who need runs on your own infrastructure against your own storage; images never leave
- •Teams or individuals who need image-bomb detection, url signing and header authorisation built into the core
- •Teams or individuals who need open-source core on github with a closed-source pro tier
- •Anyone focused on image-processing workflows
- •Anyone focused on self-hosted workflows
Best for: Stoneforge
Stoneforge is an open-source orchestration layer for running several AI coding agents at once on the same repository. The failure mode it targets is specific: once you have more than one Claude Code, Codex, or OpenCode session working on a project, they edit the same files on the same branch, two of them grab the same task, and you cannot see what any of them is doing without tabbing through terminals. Stoneforge fixes each of those in turn. Every worker agent runs inside its own isolated git worktree, so agents never collide on the filesystem, and a merge steward handles integration back to main — reviewing CI status and resolving conflicts as a separate role rather than leaving it to whichever agent finished first. A dispatch daemon tracks task priorities and dependencies and auto-assigns ready work to idle workers, so nothing gets double-claimed and nothing starts while it is still blocked. Over the top sits a real-time web dashboard at localhost:3457 that shows active agents, tasks in progress, merge requests awaiting review, and recent completions in one view, with a command palette for driving the whole thing. Roles are explicit — Director agents execute plans, Workers implement, Stewards review and merge — and recent versions added GitHub, Linear, and Notion sync so the task board can mirror the tracker a team already uses.
Ideal use cases:
- •Teams or individuals who need every worker agent runs in an isolated git worktree, eliminating cross-agent merge conflicts
- •Teams or individuals who need merge steward role reviews ci status and resolves conflicts before integrating to main
- •Teams or individuals who need dependency-aware dispatch daemon auto-assigns ready tasks to idle workers
- •Teams or individuals who need real-time web dashboard showing active agents, tasks, merge requests, and completions
- •Anyone focused on ai-agents workflows
- •Anyone focused on coding-agents workflows
