Read it later · checked 2026-10-19Can I vibecode Instapaper Premium?
YES· one-shottable
Instapaper's core is small: fetch a page, strip it down to the article with Readability, store the text, and make it searchable and highlightable. An agent can build that on SQLite with FTS5 in one sitting, and a bookmarklet that posts the rendered page covers paywalled and logged-in sites. What you give up is the phone: native apps with offline sync and a share sheet, text-to-speech with AI voices and CarPlay, Kindle and Kobo delivery, and the connected accounts. If a phone share sheet matters to you, self-hosting Wallabag or Readeck is the shorter road.

TimeOne to two hours for the first version
- Claude Code, Codex or CursorAny of them can run the prompt.
- Node.js 22better-sqlite3 compiles a native module, so build tools must be installed.
- A way to reach it from your phoneTailscale or a tunnel to the machine that runs it; the app listens on localhost by default.
- Optional: SMTP credentials and a Kindle addressOnly for the weekly digest; add your sending address to Amazon's approved senders.
Before you buildInstapaper Free already saves unlimited articles with folders and sync. You pay $5.99 for search, the permanent archive, PDFs and Kindle delivery.
- 1. Install one agent: Claude Code, Codex, Cursor.
- 2. Make an empty folder and open it in the agent.
- 3. Paste the prompt below, press enter, and answer its questions as it builds.
The prompt
Build me a personal read-it-later app to replace Instapaper Premium. Requirements: - Node.js 22 + TypeScript: a Fastify server and a React reader built with Vite. `npm start` serves http://127.0.0.1:4700; HOST in .env opens it to another interface (the README explains phone access through Tailscale or a tunnel). - Saving: POST /api/save with a URL, a paste box for several URLs, and a bookmarklet that sends the rendered page HTML so paywalled and logged-in pages still work. Fetch with `undici`, extract with jsdom + @mozilla/readability, sanitize with DOMPurify, store title, byline, site, lead image and reading time, and download images to ./data/images/. A failed extraction keeps the URL with a retry button. PDFs: save a PDF URL or upload a file, extract text with `pdfjs-dist`, show it in the same reader. - Storage: better-sqlite3 in ./data/reader.db: articles (clean HTML, plain text, status unread or archived, favourite, progress), folders, tags, highlights (quote, note, position) and an FTS5 index over title, byline and text that includes archived items. Nothing is deleted unless I delete it. - Reader: serif or sans, size and width controls, dark mode, scroll position saved per article, j / k / e / s shortcuts, and a play button that reads aloud with the browser's speechSynthesis. - Highlights: select text to highlight with an optional note; export an article's or a folder's highlights as Markdown. - Digest: an optional weekly EPUB of unread articles (`epub-gen-memory`) mailed through SMTP to a Kindle address set in .env, off by default. - Import: an Instapaper CSV export or a Netscape bookmarks file, re-fetching one URL per second with a progress bar. Export: a folder of Markdown files with front matter plus a JSON dump. - Single user with one password in .env (signed cookie). No accounts, no telemetry, local-first: the only outbound calls are fetching the pages I save and the optional SMTP send. - Out of scope: native mobile apps, a browser-store extension, AI voices, speed reading, saving X posts. - README: installing the bookmarklet, reaching the app from a phone, backing up ./data, and why sites that block servers need the bookmarklet.
Opens your agent with the prompt filled in, you press enter. Or copy it and paste it into an empty folder.
Then keep going
Next prompts, same folder.
The first prompt builds the core. Run these one at a time in the same folder to grow it into your own Instapaper Premium.
Add a Manifest V3 browser extension to the read-it-later app in this folder. Requirements: - A folder ./extension that loads unpacked in Chrome and Firefox: a toolbar button sends the current page's URL and rendered HTML to POST /api/save. - The server URL and an API token are set on the extension's options page; add token auth to the API next to the cookie login. - Show a success or error badge on the button, and a context-menu item to save a link without opening it. - Update the README with install steps for both browsers.
Add RSS output to the read-it-later app in this folder. Requirements: - GET /feeds/<secret>/<folder>.xml returns an Atom feed of the 50 newest unread articles in a folder, with the full clean HTML in content. - Each folder gets a random secret URL that can be regenerated from the folder's menu. - Add an all-unread feed in the same way. - Escape titles and sanitize content before output. - Update the README.
Add housekeeping to the read-it-later app in this folder. Requirements: - A nightly job archives unread articles older than N days (N in .env, default 60) and writes a line about each to an activity log. - A daily email through the existing SMTP settings lists ten unread articles chosen at random from the last 90 days, each with a link to the reader. - Both can be switched off in .env; an archived article stays searchable. - Update the README.
What you lose
- Native iOS and Android apps with offline reading and a system share sheet
- AI voices, text-to-speech playlists and CarPlay
- Scheduled delivery to Kindle, Kobo and Boox
- Saving posts from X and sending highlights to Notion, Evernote or Obsidian
- A hosted permanent archive that needs no server of yours
Why people still pay
The product people pay for is the phone: tap Share, the article is there offline on the train, read aloud in the car or on the Kindle. Search across years of saved reading and a copy that survives link rot come with that, and it needs no server of yours to keep running.

Take your data, then cancel.
1 · Take your data out of Instapaper Premium
- 1Open instapaper.com/settings/account, scroll to the Import section and click Export .CSV to email.
- 2Wait for the email with a link to the CSV; for a large library it can take a few hours.
- 3To read offline, open a list's three-dot menu, pick the Download section and choose ePub or PDF; each bundle holds the first 19 articles of the list.
- 4For highlights, open an article's three-dot menu, tap View Notes, then the share icon: plain text, Markdown or HTML, or send them to Obsidian, Evernote or Notion.
2 · Cancel Instapaper Premium
- 1Subscribed on the web: open instapaper.com/settings/premium and click Unsubscribe; access continues to the end of the billing period.
- 2Subscribed in the iOS app: Settings > your name > Subscriptions > Instapaper, then cancel.
- 3Subscribed in the Android app: Google Play > profile icon > Payments & subscriptions > Subscriptions > Instapaper, then cancel.
- Instapaper says it almost always grants refunds on request for web and Android subscriptions, and may prorate one asked for much later; iOS refunds go through Apple.
- Export the CSV before you cancel: the permanent archive stops applying once the subscription ends, though the docs don't say what happens to old copies.
- Instapaper can switch a web subscription from monthly to yearly; email support.
- Deleting the account is a separate step in the docs, so cancelling alone keeps your data.
