Price drops, restocks, job postings, government announcements, competitor edits - changedetection.io watches web pages and alerts you the moment anything changes, down to PDF text and checksums. Point it at a URL, set a check interval, and precise filters decide what counts as a change: a Visual Selector targets page elements by pointing and clicking, CSS selectors and XPath narrow scope, trigger-text and ignore-text rules (with regex support) cut noise, and JSONPath or jq handles API responses. A dedicated re-stock and price detection mode extracts product metadata and fires on thresholds - alert only when the price drops below your target or the percentage change exceeds a limit. JavaScript-heavy sites render through a real Chrome browser via Playwright, with the ability to execute JS steps first (log in, click, scroll) before extracting text. Notifications reach 85+ services through Apprise - Discord, Slack, Telegram, email, webhooks - optionally with a screenshot of the changed page, and AI-powered summaries (any OpenAI-compatible endpoint, including local Ollama) describe what changed. Per-watch proxies, custom headers, and POST/GET control cover hostile targets. Apache-2.0 licensed with local file-based storage: the URLs you monitor and why stay entirely your business.

Waiting for the right moment to buy usually means refreshing product pages for weeks, so PriceBuddy does the refreshing for you and speaks up when the price is right. Paste a product URL and it fetches the details and price, then rechecks on a global schedule or a per-product interval from every 5 minutes to every 24 hours. Stores are scraped with CSS selectors, regular expressions, or JSONPath, a headless browser covers JavaScript-heavy shops, and an optional AI provider (OpenAI, Anthropic, Gemini, or local Ollama) can recover missing prices or repair broken selectors. Attach several URLs to one product to compare retailers or marketplace listings, with in-stock, pre-order, and discontinued states shown beside each source. Unit pricing reveals the real cost per tablet or bag when multi-packs distort shelf prices, while history charts show minimum, maximum, and average over time. Alerts fire on a target price, a drop threshold, or a back-in-stock event and arrive by in-app notice, email, Pushover, Gotify, Apprise, Telegram, Discord webhook, or ntfy. Tags sort products into draggable dashboard groups, with optional smart sections for what to buy now, recent drops, and failed checks. Each user keeps separate products and settings, a REST API with scoped tokens serves your scripts, and a Chrome and Edge extension tracks items from the page you are viewing.

When a family vacation or group expedition spans multiple airlines, hotels, rental cars, and currencies, Surmai brings every reservation and shared cost into one collaborative travel planner. Each trip breaks down into dedicated sections for transportation legs, lodging stays, daily activities, and travel notes. Confirmation codes, terminal numbers, departure times, and street addresses stay right where everyone in your party can find them. Built-in airport, city, and airline directories auto-complete flight routes in seconds, or you can forward booking confirmation emails directly into an active trip for automatic parsing. The chronological itinerary view then weaves flights, hotel check-ins, and excursions into a clean day-by-day timeline so your group can spot layover gaps immediately. Boarding passes, train tickets, and PDF vouchers live inside a central attachment vault. Installing the Progressive Web App caches your entire itinerary and travel documents on your phone for offline viewing at airport gates or remote trailheads. A built-in expense ledger logs shared purchases across multiple currencies so nobody has to guess who paid for dinner. Administrators can invite fellow travelers over SMTP email, enable OAuth2 or OpenID Connect login with Authentik, Keycloak, Google, or Microsoft, and replicate backups continuously to S3-compatible object storage.

Commercial flight logbooks frequently lock historical travel records behind annual subscriptions or shut down unexpectedly, whereas AirTrail preserves your complete aviation history on an interactive world map under your own control. Enter a flight number to look up routes automatically or log departures manually with seat numbers, cabin classes, aircraft registrations, timestamps, notes, and custom metadata fields. Switching from another tracker takes seconds: the built-in importer ingests CSV, ICS, and JSON exports from MyFlightradar24, Flighty, App in the Air, OpenFlights, TripIt, JetLog, byAir, and JetLovers. The vector map renders geodesic flight paths, recorded GPS tracks, and airport runway details across customizable basemaps. Detailed statistics dashboards break down total distance flown, time in the air, top airlines, aircraft models, and visited countries. Families and travel groups can share a single instance with role-based permissions, OAuth single sign-on, and read-only public links, while developers automate entries through the versioned REST API or Model Context Protocol server.

A personal flight logbook you host yourself, Jetlog draws every route you have flown on a pannable world map and turns the totals into charts. The home page opens with counts of flights, airports, hours, distance, and countries above that map, where dots mark visited airports and lines trace each trajectory. Settings let markers and lines grow with visit frequency and shade the countries where you have landed. Logging a flight takes only two airports and a date. Type a flight number and press Fetch to pre-fill the origin, destination, and airline, and a utility links connection flights automatically. Duration and distance are calculated for you and stay editable, with an option to use airport time zones. The All Flights table lists route, times, duration, distance, seat, class, and airline with filters and configurable columns, and each flight opens a detail page with airport data, a route map, tail number, and aircraft. A Statistics page charts flights per month, cumulative distance, most visited airports, most common airlines, ticket class, and seat for any time frame. History arrives through MyFlightRadar24 or custom CSV imports and leaves as CSV or iCal. Family members can share one install with separate logbooks, an admin manages the accounts, and the responsive layout works on a phone at the gate.
