Projects and subtasks.
A place for the whole project.

From the first idea to the last detail. Keep your projects, everyday tasks and the work you share in one place.

Bring a little order
to the big picture.

Nest projects, break them into sections and give every next step a home. Sub-tasks carry their own dates and labels.

  • Projects within projects
  • Four levels of priority
  • Labels and saved filters
  • List, board and calendar views

Recurring tasks
for the things you do again.

Daily routines. Weekly reviews. The occasional deadline. Set your recurring work once, with due dates and deadlines kept separate.

Comments and files,
kept with the work.

Share a project, leave a comment and attach the file. Everything stays together, with attachments in your own S3 storage.

Natural-language quick add.

Dates, priorities, projects and labels, in a single line.

Read the quick-add syntax

Conatus reads dates, times, repeats, durations, deadlines, reminders, priorities, projects and labels straight out of the task name. Typing “Call the dentist next Tuesday at 2pm for 30m #Errands @urgent” files the task in Errands, labelled urgent, at 2pm next Tuesday with a 30 minute estimate.

Get the files.

Deployment files pinned to v1.2.1.

mkdir conatus && cd conatus
curl -fLO https://github.com/nojusmorkunas/conatus/releases/download/v1.2.1/docker-compose.yml
curl -fL -o .env https://github.com/nojusmorkunas/conatus/releases/download/v1.2.1/default.env.example

Make it yours.

Set your credentials before starting the stack.

Open .env and replace every replace-with-... value with a unique credential. Set CONATUS_ADMIN_USERNAME and CONATUS_ADMIN_PASSWORD for the first administrator.

CONATUS_VERSION=1.2.1CONATUS_BIND_ADDRESS=127.0.0.1

Use the loopback address for a local install or a reverse proxy on the same host. Compose checks that variables exist; it cannot detect unchanged placeholders.

Bring it to life.

Start the stack and sign in.

docker compose up -d

Open http://localhost:4399. For a domain, follow the reverse proxy guide.

Built for the long run.

Named Docker volumes keep your data persistent. A migration job runs before startup. Back up before upgrading; some migrations need a restore to roll back.

Open source.
Yours to keep.
