I live in the terminal. If I can't do it from a shell prompt, it basically doesn't exist. In order to make Tigris easier to use for developers like me, we've made a brand new Tigris CLI that lets you manage your buckets directly from your shell. Take a gander:

$ tigris cp AGENTS.md t3://xedn/AGENTS.md
Uploading object...

┌───────────┬────────┬──────────────┬───────────────────────┐
│ Path      │ Size   │ Content-Type │ Modified              │
├───────────┼────────┼──────────────┼───────────────────────┤
│ AGENTS.md │ 4.2 KB │ text/plain   │ Feb 5, 2026, 12:56 PM │
└───────────┴────────┴──────────────┴───────────────────────┘

That copied my local AGENTS.md file to my bucket in Tigris. As you can see, this new Tigris CLI gives you all the buckety goodness you know and love anywhere with a shell prompt. Even Windows. It's just an npm install away:

npm install -g @tigrisdata/cli

Then tigris login and you're good to go!

Wait, didn't you have a CLI already?

Fun fact: Tigris wasn't always an object storage company. We used to be a database company that made a database similar to DynamoDB. When we made that, we had a separate tigris command that let you interact with the database from the command line. Given that product is cancelled and offline, we've deprecated that old tigris command in favour of this new one that lets you interact with object storage.

What's different about the tigris command?

The UNIX philosophy states that each command should be as simple as possible so that complex functionality can be created by chaining programs together like how 8 simple ingredients at Taco Bell can assemble a wide array of menu options. Each of the subcommands in the tigris command follows this rule. Here are some examples so you get the idea:

• tigris login: Authenticates you to Tigris with a temporary access key.
• tigris buckets list: Lists the buckets in your current Tigris organization.
• tigris objects delete: Delete an object.

At a high level, tigris uses this pattern:

tigris DOMAIN OPERATION <ARGUMENT> --flags

This maps really cleanly to how you'd intuitively expect it to work:

• Domain: the area of concern: objects, buckets, credentials, forks, snapshots, etc.
• Operation: is the verb: list, get, put, delete, copy, move.
• Arguments: what comes after. You'll intuit your way through the rest of the program after one command, ideally so natural that you can squint at a tigris command once and then figure your way through the rest of the program.

One neat side effect of this being natural for humans is that it's also natural for our artificial coworkers to figure out thanks to them being trained on so much CLI tool documentation!

⏺ Done. yeetfile.js has been uploaded to the xe-zohar-copy bucket (4.9 KB).

No hand-holding or custom skill files required! The agent reads the help text and just figures it out. This is the kind of design we're aiming for: natural enough that both humans and AIs can figure it out without needing to read a tutorial beyond --help.

How did we get to this design?

Inside Tigris we use a Request-For-Comment flow for many of these big projects. A lot of the time in planning is spent drawing up a formal specification. We write this formal spec way before we even think about writing code. Having this all specified makes it a lot easier to iterate and gather feedback. Needless to say, this project generated a lot of feedback, probably the most out of any of these user-facing projects.

When Abdullah was working on the CLI, he wanted to write a formal specification for the CLI and then transform that into the scaffolding for the code. This eventually evolved into specs.yaml, which we parse with some custom code to generate the scaffolding required to wire everything up. This spec file ended up serving two purposes: it drove the RFC process by being the canonical source of truth for what the CLI should do, but it also was reused to generate the CLI itself. Change the spec, regenerate the CLI, everything updates and all is balanced as all things should be.

As a neat side effect of this, here's the implementation of the objects put command. It's in src/lib/objects/put.ts and directly maps to objects put. This gives us filesystem-based command routing the same way that Next.js gives you filesystem based web routing.

This spec-driven approach worked well enough that I think other teams should use it too. We're going to evolve this a bit more and make some tooling to generate CLI scaffolds in the future. Stay tuned!

Example commands

Here's some side by side examples comparing the tigris and aws commands for interacting with object storage:

Tigris Command	AWS S3 Equivalent	Description
tigris ls	aws s3 ls	List buckets or objects
tigris ls <bucket>	aws s3 ls s3://bucket/	List objects in a bucket
tigris ls <bucket>/path/	aws s3 ls s3://bucket/path/	List objects in a path
tigris mk <bucket>	aws s3 mb s3://bucket	Create a new bucket
tigris mk <bucket>/folder/	aws s3api put-object --bucket bucket --key folder/	Create a folder
tigris touch <bucket>/key	aws s3api put-object --bucket bucket --key key	Create empty object
tigris cp ./info.json t3://bucket/info.json	aws s3 cp ./info.json s3://bucket/info.json	Copy a file from the filesystem to Tigris
tigris cp t3://bucket/info.json ./info.json	aws s3 cp s3://bucket/info.json ./info.json	Copy a file from Tigris to the filesystem
tigris objects put <bucket> <key> <source>	aws s3 cp <src> s3://<dest>	Copy objects/folders
tigris objects get <bucket> <key> > test.json	aws s3 cp file.txt s3://bucket/	Upload file
tigris rm <bucket>/key	aws s3 rm s3://bucket/key	Delete object
tigris rm <bucket>/	aws s3 rm s3://bucket/ --recursive	Delete folder recursively
tigris configure	aws configure	Save credentials
tigris whoami	aws sts get-caller-identity	Show current user info
tigris logout	(no direct equivalent)	End session

note

You can also use t3 as shorthand for tigris in the CLI!

See how much simpler that all is? We think that making these commands direct like this will make it a lot easier for you to understand and work with Tigris.

The real star: tigris cp

My favorite subcommand is cp (copy). It does everything you'd expect from the UNIX tool cp on your local machine, but it understands t3:// URLs. This means you can copy files between buckets, download stuff, upload stuff—all with one command that behaves exactly like you'd expect:

# Copy a remote object to a new location
tigris cp t3://my-bucket/my-path/my-object.json t3://my-bucket/new-path/my-object.json

# Copy a remote folder recursively
tigris cp -r t3://my-bucket/my-path/ t3://my-bucket/new-path/

# Copy with wildcard
tigris cp t3://my-bucket/my-path/*.json t3://my-bucket/new-path/

# Download a remote object to local
tigris cp t3://my-bucket/my-file.txt ./local-file.txt

# Download a folder to local
tigris cp -r t3://my-bucket/my-path/ ./local-dir/

# Upload a local file to remote
tigris cp ./local-file.txt t3://my-bucket/my-file.txt

# Upload a local folder to remote
tigris cp -r ./local-dir/ t3://my-bucket/my-path/

See that t3:// prefix? That's our URL scheme for Tigris objects. Your brain already knows how cp works; we just made it work with object storage too.

Frequently Asked Questions

Is the Tigris CLI free to use?

Yes! The Tigris CLI is completely free and open source. You can install it with npm install -g @tigrisdata/cli and start managing your object storage immediately. Tigris also offers a generous free tier for storage and bandwidth.

Does the CLI work on Windows?

Yes, the Tigris CLI is cross-platform and works on Windows, macOS, and Linux. Since it's distributed as an npm package, it works anywhere Node.js is installed—including Windows PowerShell, Command Prompt, and Windows Terminal.

Can I use Tigris CLI with existing AWS S3 workflows?

The Tigris CLI follows similar patterns to AWS S3 commands, making migration straightforward. See the comparison table above for command equivalents. However, the Tigris CLI uses a more intuitive, UNIX-philosophy syntax (like tigris cp instead of aws s3 cp) that's designed to be easier to remember and type.

How do I authenticate with the Tigris CLI?

Run tigris login to authenticate with a temporary access key, or use tigris configure to set up a long-lived authentication keypair. Both methods will store your credentials securely for future sessions.

Is Tigris S3-compatible?

Yes, Tigris provides an S3-compatible API. While the Tigris CLI offers a more natural command interface, you can also use existing S3 tools with Tigris if needed.

Can AI assistants use the Tigris CLI?

Yes! The CLI is designed with discoverable help text that AI assistants can understand and use. Commands follow the pattern tigris DOMAIN OPERATION, so you can ask an AI to "upload this file with tigris" and it can typically figure out the correct command from --help output.

Conclusion

Please try the CLI out! It's open source on GitHub. We use it internally at Tigris. We plan to replace the AWS CLI with our CLI company-wide–there's only so many times you can type aws s3api before your fingers fall off.

Install our CLI with npm:

npm install -g @tigrisdata/cli

Then run tigris login to get started or tigris configure to set your authentication keypair. You'll be authenticated and ready to upload files within seconds.

Try it out! Let us know what you think! We're still balancing familiarity with natural design, and real feedback beats internal speculation every time. Open an issue on GitHub, stop by our Discord or reply wherever you found this post.

The shell is waiting.
