Why does your project use PostgreSQL instead of the document store everyone assumed? Is the reasoning written down, or does it live with whoever was in the room? Architecture Decision Record Generator writes that record, in the standard format teams already use, from a description of the decision you made.

What is Architecture Decision Record Generator?

It is a free tool that writes architecture decision records. An ADR is a short document capturing one decision, the situation that forced it, and what follows from it. You describe the choice in plain language and the tool produces the record in your chosen template, ready to commit alongside the code it affects.

What An ADR Contains

Context

The constraints and pressures at the time, which is what makes the decision legible later.

Decision and status

What was chosen, stated plainly, with a status showing whether it still stands.

Alternatives and consequences

What else was on the table, and what the team accepts as the cost of this choice.

How Does Architecture Decision Record Generator Work?

  1. Describe the decision and the situation that forced it.
  2. Pick a model, then choose an ADR Template, a Decision Status and an Audience.
  3. Generate, then copy the record into your repository as a numbered file.

The Output Length slider runs from Very Short to the fullest treatment, and four toggles decide the extras: List alternatives considered, Include trade-offs table, Add consequences section and Note related decisions.

Template, Status And Tone

OptionWhat it decidesWhere to start
ADR TemplateNygard, MADR, Y-statement, Lightweight or Full enterpriseNygard, the classic and most widely recognised
Decision StatusProposed, Accepted, Deprecated, Superseded or Under reviewProposed while it is still being discussed
ToneNeutral and factual, persuasive, concise or thoroughNeutral, because a record is not an argument
AudienceEngineering team, review board, future maintainers or stakeholdersFuture maintainers, who are the real readers

Tip Write the record while the decision is being made, with the status set to Proposed. An ADR written afterwards tends to justify the choice rather than record the reasoning.

Who Reads It Later

Almost never the person who wrote it. The audience is a developer two years out, wondering why the system works this way and whether they are allowed to change it. That is why the context section matters more than the decision section: a constraint that has since disappeared is the clearest possible signal that the decision can be revisited.

Judging The Draft

Check three things. Does the context describe the situation rather than the solution? Are the alternatives real ones you actually weighed, not straw options? Do the consequences include the costs you are accepting, not only the benefits? A record listing three advantages and no downside was written to win an argument, and readers can tell.

Nothing on EizTools needs a subscription or an account, and there is no daily cap, and a model selector on every page lets you rewrite a section that came back too promotional. Architecture Decision Record Generator sits with the architecture and documentation tools in the coding tools category, each with its own options panel rather than a shared one.

Frequently Asked Questions

Which template should I choose?

Nygard if your team has no convention yet. MADR suits teams that want more structure, and Lightweight works for small decisions that still deserve a record.

How long should an ADR be?

One page. Records longer than that stop being read, and the value of an ADR comes entirely from someone reading it years after it was written.

What happens when a decision changes?

Write a new record and set the old one's status to Superseded, with a link between them. Editing history away removes the reasoning that made the change sensible.

Do small decisions need records?

Only the ones that will confuse someone later. A useful test is whether a new joiner would ask why, and if so the decision is worth a record.

Architecture decisions are made quickly and questioned slowly. Writing them down costs ten minutes and answers a question that would otherwise be asked in a meeting, from memory, by people who were not there.
