ToolJet vs Heroku: at a glance
What is ToolJet?
An LTS patch train quietly absorbing security fixes and multi-model AI switching
ToolJet's 3.20.x LTS line ships near-daily patch tags, most carrying a single merged PR. The substantive items in the current window are LLM switching with query transformation in the AI layer, two-factor authentication, a fix for cross-tenant vulnerabilities in ToolJet DB, and CSV import for ToolJet DB. Everything else is single-fix housekeeping - event handler ordering, layout deduplication, signup guard changes.
What is Heroku?
Runtime bumps most weeks, but a new stack, a stack deprecation and an AI model cull underneath
Heroku's changelog is dominated by runtime maintenance - Node.js, .NET, Python, Ruby, Go and PHP updates land most weeks, often several in a day. Beneath that cadence the platform shipped real structural changes over May and June 2026: Heroku-26 reached general availability while Heroku-22 was deprecated, Heroku Connect opened to independent software vendors, a GitHub Enterprise Cloud integration arrived, Custom Trusted IPs came to Fir Private Spaces, and the CLI moved credential storage into system keychains. On the AI side, Heroku added Claude Opus 4.8 support in late May and then began deprecating select models from Managed Inference and Agents a week later.

An LTS patch train quietly absorbing security fixes and multi-model AI switching
◆ Current state
ToolJet's 3.20.x LTS line ships near-daily patch tags, most carrying a single merged PR. The substantive items in the current window are LLM switching with query transformation in the AI layer, two-factor authentication, a fix for cross-tenant vulnerabilities in ToolJet DB, and CSV import for ToolJet DB. Everything else is single-fix housekeeping - event handler ordering, layout deduplication, signup guard changes.
◆ Where it's heading
The LTS branch is doing two jobs at once. It is the stability line, which explains the volume of one-PR tags, but real capability is still landing on it - AI model switching and CSV import are not backports of cosmetic fixes. The security items are the more telling signal: two-factor authentication and a cross-tenant isolation fix arriving in the same tag point at a product being hardened for multi-tenant deployments where one customer's data reaching another is the failure that matters.
◆ Prediction
Expect the 3.20.x LTS cadence to continue at roughly a tag a day with further AI-layer work following the LLM switching groundwork. The entries do not show what is happening on the non-LTS branch, so how much of this originates there is not visible here.

Runtime bumps most weeks, but a new stack, a stack deprecation and an AI model cull underneath
◆ Current state
Heroku's changelog is dominated by runtime maintenance - Node.js, .NET, Python, Ruby, Go and PHP updates land most weeks, often several in a day. Beneath that cadence the platform shipped real structural changes over May and June 2026: Heroku-26 reached general availability while Heroku-22 was deprecated, Heroku Connect opened to independent software vendors, a GitHub Enterprise Cloud integration arrived, Custom Trusted IPs came to Fir Private Spaces, and the CLI moved credential storage into system keychains. On the AI side, Heroku added Claude Opus 4.8 support in late May and then began deprecating select models from Managed Inference and Agents a week later.
◆ Where it's heading
Two things are happening at once. The platform layer is going through a generational turn - a new stack promoted, the previous one deprecated, and enterprise-facing controls (trusted IPs, keychain credentials, ISV access, GitHub Enterprise) filling in around it, which is the profile of a mature PaaS defending its installed base rather than chasing new workloads. The AI layer is behaving differently: adding a frontier model and pruning others within days points at a curated, opinionated inference catalogue rather than a broad marketplace. The relentless buildpack cadence is the constant underneath both.
◆ Prediction
Expect the Heroku-22 deprecation to progress toward an end-of-life date and further consolidation of the Managed Inference model list. The entries do not indicate what replaces the deprecated models, so whether the AI catalogue is narrowing or being re-based is not yet visible.
