AddCal makes you a calendar link in 5 seconds: unlimited, on every plan, including free.

The same enterprises Trumba sells to, without the spuds. 5-second setup No sales call Published pricing ### TL;DR: The quick version - **Self-serve in seconds** vs a 7-step implementation guide, startup wizard and staging cycle - **Every feature on at signup**, with no "contact Support to enable" and no sales call between you and your first link - **Unlimited adds & clicks and published pricing** vs capped analytics and a sales-gated quote - **Honest note:** Trumba is a heavier enterprise platform. It genuinely does more: paid ticketing, room scheduling, custom objects. AddCal leaves those out on purpose. **Bottom line:** Trumba is a project. AddCal is a product. If you want audience reach without the implementation, AddCal is the faster path. Trumba's audience reach without Trumba's implementation project ----------------------------------------------------------------- Three differences do most of the work when people switch. ### Self-serve, not an implementation project Trumba ships a 7-step implementation guide, a startup wizard with sample events you clear by hand, and a stage-then-deploy cycle. AddCal: sign up, first event in 5 seconds. No wizard, no staging environment. ### Everything on, nothing sales-gated Trumba's paid registration, custom objects, resource scheduling and data Connector all say "contact Support to enable." Every AddCal feature is live the moment you sign up, with no sales call between you and your first link. ### Unlimited & transparent, not capped & quoted Trumba caps analytics to a rolling 3 months, caps event forwarding, and gates pricing behind sales. AddCal is unlimited adds and clicks on every plan including free, with full analytics history and published pricing (from $12/mo). Why people look for a Trumba alternative ------------------------------------------ We hear the same friction over and over from people leaving Trumba. ### Setup is a project, not a signup A 7-step implementation guide, a startup wizard with sample events you must clear by hand (no undo), and a staging-then-deploy cycle stand between you and your first published calendar. ### The good features are behind sales Paid registration, custom objects, resource scheduling and the data Connector all need Trumba Support to switch on for you. There is always a gate, and often a quote, between you and the feature. ### Capped limits and quoted pricing Analytics is a rolling 3-month window, event forwarding is capped at 10-50 friends, and there is no published price, so you request a quote and wait. Growing programs hit those walls fast. Why teams switch from Trumba to AddCal ---------------------------------------- ### Live in 5 seconds Sign up and create your first event in seconds, with no implementation guide, no staging, and no support ticket to enable features. ### No sales gate Every feature is enabled the moment you sign up. Nobody has to turn anything on for you, and there is no quote to chase. ### Unlimited & published pricing Unlimited adds and clicks on every plan including free, with published pricing from $12/mo, no rolling analytics cap, and no forwarding limits. ### Modern integrations Real-time sync, webhooks, Smart Links, Zoom and 8000+ Zapier apps, instead of Google sync that lags hours and a poll-only CSV API.

Trumba is a publishing platform you implement; AddCal is a product you sign up for. Everything is on from your first minute, and the price is on the page. ### Core Calendar Features | Feature | AddCal | Trumba | | --- | --- | --- | | Add-to-calendar links (Google/Apple/Outlook/M365/Yahoo) | | | | Subscription calendars (auto-sync) | | | | Calendar views (month/week/list) | | | | RSVP / registration | | | | Embeddable widgets [ AddCal Advantage ] | One snippet | Spuds (manual JavaScript) | | Multi-format feeds (iCal/RSS/JSON/CSV) | Subscription feed | iCal/RSS/JSON/CSV | | Real-time sync [ AddCal Advantage ] | Real-time + webhooks | Google sync lags hours | Both platforms cover the everyday calendar work. AddCal does it with one universal link and one embed snippet; Trumba does it with published calendars and "spuds": manual JavaScript snippets that need a developer. ### Integrations & Automation | Feature | AddCal | Trumba | | --- | --- | --- | | Smart Links (dynamic event creation) [ AddCal Advantage ] | | | | Zapier (8,000+ apps) [ AddCal Advantage ] | | | | Zoom integration | | | | Webhooks [ AddCal Advantage ] | | | | ICS calendar import | | | AddCal is built for modern automation. Smart Links create events straight from a URL (idempotent, so a webhook firing twice never duplicates), and webhooks fire in real time. Trumba has no Zapier, no webhooks and no equivalent to Smart Links. ### Analytics & API | Feature | AddCal | Trumba | | --- | --- | --- | | Analytics history [ AddCal Advantage ] | Full history, no cap | Rolling 3-month cap | | API [ AddCal Advantage ] | REST, granular tokens, on free tier | Poll-only CSV, BASIC auth | AddCal keeps your full analytics history and offers a REST API with granular tokens on every plan, including free. Trumba caps analytics to a rolling 3 months, and its registration "API" is poll-only CSV with BASIC auth. ### Enterprise machinery (where Trumba does more) | Feature | AddCal | Trumba | | --- | --- | --- | | Paid registration / ticketing | | | | Room / resource scheduling | | | | Custom objects / directories | | | | 6–7 tier permissions | | | We keep these honest. Trumba is a heavier, enterprise publishing platform and genuinely does more here. AddCal leaves this out on purpose. It is a different product for a different job. If you need paid ticketing or room scheduling, Trumba is the heavier tool. Who should switch (and who shouldn't) --------------------------------------- ### AddCal is a good fit if you... - Inherited a Trumba calendar and want out of the implementation and jargon - Want published pricing and instant setup, not a sales-gated quote - Need add-to-calendar links, subscriptions, embeds and RSVP, not room scheduling - Want Smart Links, webhooks, Zapier and real-time sync - Want unlimited adds and clicks with full analytics history ### Trumba might still be right if you... - Need paid registration and ticketing with payment gateways - Run room and resource scheduling for a campus or venue - Rely on custom objects, directories or 6–7 tier permission hierarchies - Have an enterprise IT committee that wants the full publishing platform Moving off Trumba is paste-and-go ----------------------------------- Import your events in minutes, then re-share one permanent AddCal link. From there it never breaks again, even if you rename things, unlike Trumba where a web-name change breaks every embed. 1 ### Export from Trumba Grab the .ics feed Trumba auto-generates for each published calendar. 2 ### Import into AddCal Go to Import → ICS, then paste the feed URL or upload the file. 3 ### Share your permanent link Your events land in a new calendar with a share link that never breaks. **Good to know:** ICS import is a one-time import, not a live recurring sync from Trumba. If you need your AddCal calendar to keep pulling from an external source on a schedule, use AddCal's external calendar sync feature instead.

Frequently Asked Questions ---------------------------- Common questions about switching from Trumba to AddCal ### Is AddCal a true Trumba alternative? For the ~95% of Trumba use cases (publishing a calendar, add-to-calendar links, subscriptions, embeds and RSVP), yes, and with far less setup. AddCal deliberately doesn't do paid registration, room/resource scheduling or custom-object directories; if you need those, Trumba is the heavier tool. ### How much does AddCal cost vs Trumba? AddCal publishes its pricing: a genuinely unlimited free tier, plus paid plans from $12/mo ($20/mo for Business). Trumba's pricing is sales-gated, so you have to request a quote. ### How long does it take to switch from Trumba? Minutes. Export your Trumba calendar as an .ics feed and import it into AddCal. Your new AddCal share link is permanent and won't break when you rename things. ### Does AddCal do everything Trumba does? No, and on purpose. AddCal skips Trumba's enterprise machinery (payment gateways, room scheduling, 6-7 tier permissions, custom objects). It focuses on getting people to add events and show up, with unlimited usage and no jargon. ### Will my embedded calendar break if I rename it? No. AddCal links are permanent. Trumba's "web name" changes break every embed and feed that referenced the old name. ### Does AddCal have real-time sync? Yes. Real-time sync, webhooks and 8000+ Zapier apps. Trumba's Google sync can lag a few hours and its registration "API" is poll-only CSV. Skip the implementation call ------------------------------ You can have a working, shareable, unlimited calendar before Trumba's onboarding email lands in your inbox.
