LibreSpeed vs Heroku
A side-by-side editorial comparison of LibreSpeed and Heroku — release velocity, themes, recent moves, and the top alternatives to consider.
LibreSpeed vs Heroku: at a glance
What is LibreSpeed?
After a two-year redesign, LibreSpeed is adding tests instead of polishing pixels.
LibreSpeed is a self-hosted speed test that spent roughly two years landing a new frontend design, shipped it behind a feature switch, then promoted it to default in 6.0.0. With that out of the way, 6.2.0 turns to capability: a standalone connection-stability test with live latency charting, packet-loss tracking, alerts and CSV export, plus PWA metadata so the tool can be installed from a browser. Docker deployment has been reworked in parallel, including a port change and PHP limits that were silently rejecting default upload chunks.
What is Heroku?
Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.
Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.

After a two-year redesign, LibreSpeed is adding tests instead of polishing pixels.
◆ Current state
LibreSpeed is a self-hosted speed test that spent roughly two years landing a new frontend design, shipped it behind a feature switch, then promoted it to default in 6.0.0. With that out of the way, 6.2.0 turns to capability: a standalone connection-stability test with live latency charting, packet-loss tracking, alerts and CSV export, plus PWA metadata so the tool can be installed from a browser. Docker deployment has been reworked in parallel, including a port change and PHP limits that were silently rejecting default upload chunks.
◆ Where it's heading
The redesign was the blocker; now that it is default, releases are moving outward — a second measurement mode, installability, better multi-server list handling. The Docker thread runs alongside and is where the breaking changes live: default port moved from 80 to 8080 in preparation for rootless operation, post_max_size raised to accept the tool's own 20 MiB chunks, Alpine base updated. Much of the recent throughput comes from outside contributors and automated agents rather than a single maintainer.
◆ Prediction
Expect the stability test to gain the configuration and server-side plumbing the main speed test already has, and the rootless-container work that the port change was preparation for to land next. Nothing in the entries suggests a change to the project's self-hosted, no-backend-dependency positioning.
Heroku
5.0DEVOPSINFRA · APIS
Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.
◆ Current state
Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.
◆ Where it's heading
The platform is running two clocks at once. One is a near-daily maintenance cadence that keeps supported runtimes current and rarely changes behaviour. The other is a deliberate, publicly staged lifecycle for the data services, where a major version is walked from beta to GA and the version three releases behind is retired in the same announcement. Kafka is on the same track, with 2.8 and 3.7 deprecations and a revised version-support policy posted in late July.
◆ Prediction
Given that Postgres 15's deprecation was announced alongside 18's general availability, the next concrete step is a published end-of-life date and forced-upgrade window for Postgres 15. The runtime bumps will continue at their current weekly rhythm.
