The problem
Engineering decisions get lost
1.1
Slack discussions disappear.
Teams debate architecture in threads that vanish. No trace, no reasoning, six months later.
1.2
Docs become outdated.
Decisions are buried in long pages nobody revisits. The "why" is always the first casualty.
1.3
New engineers lack context.
People join and can't understand why systems were built a certain way. Repeat mistakes follow.
Example record
ADR-001 — Adopt Postgres instead of DynamoDB
Decision lifecycle
Track every transition
A decision is under discussion. The team weighs in here, not in Slack.
The team agrees. Decision finalized with a review date. Permanently recorded.
A newer decision replaces it. Full history preserved — the reasoning survives.
How it works
Three steps to a structured decision
Document
Capture the problem, options considered, decision, and trade-offs. Assign a reviewer and a review date.
Discuss
Comments thread directly on the record — no switching tools, no context lost to Slack.
Track the lifecycle
Proposed → Accepted or Superseded. Tags, review dates, full-text search.
FAQ
Common questions
What is an Architecture Decision Record (ADR)?
An ADR captures an important technical decision along with its context and consequences — the problem, options considered, the decision made, and the known trade-offs. Decision Log gives every ADR a permanent, structured home with a full lifecycle.
How is this different from Confluence or Notion?
Decision Log is purpose-built for engineering decisions. It enforces an ADR structure, tracks lifecycle states (Proposed → Accepted → Superseded), integrates with GitHub PRs, and surfaces analytics on review coverage. Confluence and Notion are general-purpose — decision context inevitably gets buried.
Does it integrate with GitHub?
Yes. Connect via a GitHub App and Decision Log posts a status check on PRs that touch architectural files (Dockerfile, schema.sql, terraform, etc.). The check blocks merge until a linked decision is Accepted. Patterns are fully configurable.
What do Proposed, Accepted, and Superseded mean?
Proposed means the decision is under discussion. Accepted means the team has agreed and it's final. Superseded means a newer decision replaced it — the original record is preserved so the reasoning survives even after the technology changes.
How many decisions can I log for free?
The free plan includes up to 25 decisions and 1 workspace — enough to get started and build the habit. Paid plans remove all limits.
