Best Free & Open Source Alternatives to Figma

Penpot is a free, open-source design and prototyping platform from Kaleidos, released under the Mozilla Public License 2.0. It runs entirely in the browser and keeps designs in SVG, so files stay portable and readable on the open web instead of being locked into a proprietary format. You can use it on Penpot's hosted cloud or self-host it with Docker.

Penpot covers the full product design workflow: vector editing with boolean operations, Flex and CSS Grid layouts, components with variants, shared libraries, and native support for the W3C Design Tokens Community Group format. Designers can build interactive prototypes with triggers, overlays and flows, while developers get inspect and code views that map to real CSS. Real-time collaboration, comments, custom fonts and RTL support round out the editor, and an open plugin API plus a free MCP server connect Penpot to AI agents and custom workflows.

Penpot is developed in the open with frequent releases (currently the 2.x line, including a WebGL renderer and stroke-to-path). The free plan suits individuals and small teams, while paid Unlimited and Enterprise plans add storage, longer version history, SSO/SCIM, audit logs, advanced permissions and a private server option. Teams leaving Figma or Adobe XD can migrate with the Penpot Exporter plugin or MCP-based workflows.

App Store Screenshots Generator is a skill for AI coding agents that scaffolds a production-ready Next.js editor for App Store and Google Play marketing screenshots. Instead of a static one-off export, the agent builds a full editor on your machine with a connected canvas, real device frames, inspector controls, persistent project state, and one-click export bundles at every store-ready size. You describe your app, its key features, and a visual direction in plain language, and the agent generates the deck.

The editor covers iPhone, iPhone Duo, iPad, Apple TV, Apple Watch, CarPlay, Mac, Android phones, Android tablets, and Play Store feature graphics, plus a universal 5244 x 2950 creative asset for the App Store product page header and search results. Element spans across adjacent screenshots on a connected canvas and each screen is exported as a precise crop; an isolated-screen export mode keeps legacy decks unaffected. The toolbar includes a Style Lab for remixing palette, type, layout and scene with locks, a Scene Playground with backdrops and device tilt effects, a magnifier loupe for highlighting details, and 18 named visual styles with a headline copy library.

Where AppScreens and Previewed are hosted web editors with subscription tiers, this project is MIT-licensed and runs entirely on your own machine: every deck is saved to an app-store-screenshots.json file that is git-trackable and resumable, and the editor autosaves through a local API endpoint with revision detection to guard against concurrent edits. Screenshots generated with the skill have been accepted on a live App Store listing (Bloom Coffee Shelf Recipe). It installs in agents such as Claude Code, Cursor, Windsurf, OpenCode and Codex via npx skills add ParthJadhav/app-store-screenshots.

Huly (built on the Hardcore Engineering platform) is an open source all-in-one productivity suite designed to replace a stack of paid tools with a single self-hostable application. It bundles an issue tracker, project planner, team chat, wiki, CRM, HR, ATS, and even quality management into one cohesive workspace.

It positions itself as a direct alternative to Linear and Jira for engineering teams, while also replacing Notion or Coda for documentation, Slack or Discord for chat, HubSpot for CRM, and Motion for AI scheduling. Because all modules share a single data model, work items, conversations, contacts, and documents stay in sync without glue code or paid integrations.

Huly is built with TypeScript and runs on Node.js and MongoDB, with first-class Docker and Kubernetes support. The community edition is fully open source under EPL-2.0, while a cloud-hosted tier is available for teams that do not want to manage infrastructure.

OpenPencil is an open-source design editor that reads and writes native .fig files alongside its own .pen format. It ships as a roughly 15 MB Tauri desktop app for macOS, Windows, and Linux, as a browser PWA, and as a CLI, so the same document can move between a local app and the web.

The editor covers components and variants, flex and CSS Grid auto layout via Yoga WASM, variables, styles, design tokens, image vectorization, and design-to-code export to JSX/Tailwind, Storybook stories, PNG, JPG, WEBP, SVG, PDF, and PPTX. Real-time collaboration is peer-to-peer over WebRTC, with no server or account, and includes cursors, presence, follow mode, and voice calls. AI features let you describe a design in chat and have the assistant create or modify nodes through more than 100 tools, using OpenRouter, Anthropic, OpenAI, Google AI, DeepSeek, Z.ai, MiniMax, or compatible endpoints.

Compared with Figma's seat-based, cloud-first subscriptions, OpenPencil is MIT-licensed, works offline in the desktop app, and opens existing .fig files, so you can bring designs over and copy-paste nodes between the two. It is also programmable: the headless CLI supports XPath queries, linting, format conversion, and the Figma Plugin API via eval, plus an MCP server and agent integrations for Claude Code, Codex, and Gemini CLI. The project describes itself as usable today but still under active development, with rough edges as features evolve.

Tegon is an open source, developer-focused issue tracking and project management tool. It is positioned as a clean, modern alternative to Jira and Linear with an emphasis on fast workflows, keyboard shortcuts, and AI-assisted triage.

Tegon ships with issues, projects, sprints, cycles, and roadmaps out of the box, plus a notification model and integrations designed for engineering teams. The product roadmap also includes AI-driven suggestions for assigning, prioritising, and summarising work, and the codebase is structured so teams can self-host and extend it with their own integrations.

Tegon is released under AGPL-3.0 and is built on TypeScript and React. It is a good fit for small engineering organisations that want a no-per-seat, self-hosted Jira replacement without the operational overhead of running something heavier.
