Sigle is an open-source writing platform for web3 writers that stores content outside centralized platforms: independent creators, NFT projects, and crypto analysts who publish stories and newsletters. Built on Stacks with decentralized Gaia storage and newer Bitcoin Ordinals support, it promises that you own your content, economy, and data instead of renting an audience from a centralized feed. The hosted app at app.sigle.io is free to start, with a paid Creator plan for premium features.[1][2][3]
Quick verdict
Open-source Web3 publishing with user-owned storage, newsletters, and SEO blogs. Sigle is an MIT-licensed, open-source writing platform for web3 creators, built on Stacks with decentralized Gaia storage and Bitcoin Ordinals support. It covers stories, newsletters, custom-domain SEO blogs, and analytics, free to start with a paid Creator plan. Wallet-based identity and manual saving are the main workflow costs; SSO, offline use, and data regions are unverified.[1][2][3]
What Sigle can do
Stories can be stored on IPFS or locked immutably on the Bitcoin blockchain as Ordinals, so published writing survives independently of any single host.[1][2]
The dashboard editor covers titles, rich content, cover images, manual save, drafts, publishing to your blog, and reusable templates such as newsletters and roadmaps.[1]
Newsletters are generally available with subscribe modals and cards, a dashboard newsletter page, Mailjet list and sender selection, and test emails before publishing.[1]
Writers can serve SEO-ready custom blogs on their own domains with analytics and a discover page, with custom domains in beta.[1][2]
Monetization tooling includes NFT-gated content via Unlock Protocol and Stripe connections, with preferred-currency choice marked as coming soon at observation time.[1]
Who it fits
Independent web3 writers who want censorship-resistant publishing and portable, user-owned content are the core fit: the product story is built around creators keeping their archive and community.[1][2]
Crypto and NFT projects running blogs plus newsletters fit well, since newsletters, custom domains, and gated content match project publishing needs.[1][2]
Writers motivated by platform risk fit best: if deplatforming, shadow banning, or losing your archive and subscriber relationships would cost you more than wallet onboarding, Sigle's ownership model answers that concern directly.[1][2]
Writers deciding between open-source newsletter platforms should compare Ghost first: it is the closest catalogue alternative, with custom themes and paid subscriptions. Prefer Ghost for mainstream audiences and mature membership tooling; prefer Sigle when decentralized, user-owned storage is the requirement.[1][2]
Limitations to weigh
Saving is still manual: closing a tab or leaving the dashboard without saving loses content, which is a real workflow risk for long drafts.[1]
Writing requires a Stacks/Leather wallet identity, so readers and writers outside the Stacks ecosystem face onboarding friction that hosted platforms do not impose.[1][2]
Unknowns to verify before committing: no evidenced statements on SSO, offline writing, datacenter regions, or Creator plan pricing were found on the researched official pages.[1][2]
General-interest newsletters whose audience lives entirely outside web3 carry extra friction here: wallet-based identity and crypto-adjacent positioning add onboarding cost with no payoff for those readers.[1][2]
Compatibility and integration
Content is reachable through open APIs and the protocol supports switching clients without losing content, so integrations read from decentralized storage rather than a proprietary database.[1][2]
The stack is TypeScript with Next.js apps, a server API, Docker Compose services, and PostgreSQL with Prisma, which is familiar ground for JavaScript teams evaluating contributions or self-hosting.[1]
The client is MIT-licensed and openly developed, so teams can inspect, contribute to, or run their own publishing client rather than depending on a closed hosted-only editor.[1][2]
Questions worth asking
Is Sigle free, and what does the Creator plan add?
Yes. The FAQ states Sigle is totally free, with a paid Creator plan that adds exclusive premium features. Explorer Guild NFTs grant free lifetime access to the Creator plan. Exact Creator plan prices were not documented on the researched pages, so compare current pricing on the official site before budgeting.[1]
Where is my writing stored on Sigle?
Your writing is stored on Gaia, the decentralized Blockstack/Stacks storage hub built around user control of data, with newer support for locking writing immutably on the Bitcoin blockchain via Ordinals. You can write anonymously if you wish. This is decentralized application storage, not a stated datacenter region, so regulated data-residency needs remain unverified.[1][2]
Can I run a newsletter and a custom-domain blog on Sigle?
Yes. The changelog records newsletter capabilities going from beta to generally available, with a dashboard newsletter page, subscribe modals and cards, Mailjet list and sender selection, and test emails before publishing. Custom domains are in beta and SEO settings are documented in the writing guides.[1][2]
Can I self-host Sigle instead of using the hosted app?
The repository is MIT-licensed and documents a local Docker Compose setup, so running your own client is supported in principle. Expect a moderate multi-service setup (Node 24+, pnpm, Docker, PostgreSQL with Prisma) rather than one-click hosting, and plan on the hosted app at app.sigle.io unless you staff the self-hosted route.[1][2]
