Read MoreJitsi's own handbook gives the figures: 8 GB suggested, 4 GB for small meetings, 2 GB for tests, and bitrates per resolution. This guide sizes a server from them and prices three configurations.
Read MoreosTicket's prerequisites are short: PHP 8.2 to 8.4, MySQL 5.5 or better, URL rewrite enabled. This guide adds the sizing the docs leave out and prices a help desk for a small, medium and large team.
Read MoreDrupal's requirements pages are precise about PHP: a 64 MB memory_limit minimum, 128 or 256 MB on production systems, PDO, GD and DOM. This guide sizes a Drupal site from them and prices three layouts.
Read MoreMoodle's installation page gives a 512 MB floor and a 1 GB recommendation. Enrolment counts do not size a Moodle; concurrent users do. Here is how to size by that and what it costs.
Read MoreMattermost's pricing page lists no public per-seat price; its licences are annual and self-hosted is the default model. Here is what the free edition needs to run for a team, and what that server costs.

Read MoreSlack's 90-day history limit and a client's data-residency clause pushed a 200-person firm to Mattermost. Here is what the move looked like, and what it costs per month.
Read MoreThe install takes a click. Production takes a checklist: a certificate the mobile apps trust, a firewall that only opens 443, nightly database dumps and a node that grows on Monday mornings.
Read MoreEvery deploy, failed pipeline and memory alert lands in one Mattermost channel. The trick is that Mattermost speaks Slack's webhook format, so the platform's Slack add-on works unchanged.
Read MoreSelf-host Mastodon on Ubuntu: why federation sets the sizing, the five services, LOCAL_DOMAIN and the keys you cannot lose, media retention, Postgres tuning.
Read MoreOdoo Online will not run the custom module the warehouse needs. Odoo.sh needs Enterprise. A distributor prices the third option: Community Edition on a PaaS environment it owns.
Read MoreThe module worked on the developer's laptop and broke on production's data. A clone of production, updated with one command and deleted after lunch, is the fix that costs cents.
Read MoreOdoo was fine for 27 days and unusable for 3. The fix was not a bigger server all month: it was cloudlets that appear when accounting closes the books and disappear afterwards.

Read MoreClients should not need an account to join a privileged call, and the recording should never leave the firm. A managing partner prices a Jitsi server against 60 Zoom licences.
Read MoreForty classrooms of fifteen students at 09:00, nothing at 15:00. The engineer works out what the videobridge really needs, lets the node scale by the hour, and knows when to add a second bridge.
Read MoreThree applications, one video server. Moodle classes, Nextcloud calls and Mattermost meetings all open rooms on the same Jitsi, with a signed token saying who may create them.

Read MoreJira Cloud charged per user for a team where half the users only log time. Redmine gave the firm multi-project tracking, Gantt charts and time sheets on an environment it owns.

Read MoreSelf-host Forgejo on Ubuntu: how it compares with GitLab, sizing, systemd setup, the app.ini settings that matter, Forgejo Actions and complete backups.
Read MoreThe ethics board wanted to know where 40,000 students' responses would live. A research office answers with a LimeSurvey environment in London that grows for launch day and shrinks after.
Read MoreFive thousand sensors publishing every thirty seconds need a broker that is always there and trusts nobody by default. Here is a Mosquitto deployment that is both, on a node that costs a few dollars.

Read MoreFour PHP content systems, one click each, and a technical director who refuses to build every site on the same one. Here is which brief got which CMS, and why the platform made the choice cheap.
Read MoreFive Java content systems that a card cannot distinguish. One is a portal, three are web CMSs of different weights, one is a document repository. A university sorts its needs across them.
Read MoreThe team writes Python and did not want a PHP CMS to be the one thing they could not extend. django CMS gave them front-end editing inside a Django project they own end to end.
Read MoreA wiki, a project tracker, a Git server and a webmail client, each one click, each a few cloudlets. A six-person firm runs all four for less than one of the subscriptions they replaced.
Read MoreA regional currency with 4,000 members needed a ledger it could trust and run itself. Cyclos gave the cooperative accounts, transfers and mobile payments; the platform gave it a home that stays up.
