Terms of Use
Last updated: March 20, 2026
Definitions
- "Assembled," "we," "us," or "our" means Assembled, Inc., a Delaware corporation that operates the hosted service at 143.dev.
- "You" or "User" means the individual accessing or using the service, or the entity on whose behalf that individual is accessing or using the service.
- "Organization" means the company, team, or other legal entity that has established an account on 143.dev and invited or authorized Users to access its workspace.
- "Administrator" means a User designated by the Organization with the authority to manage workspace settings, integrations, members, and access controls.
- "Service" means the hosted platform and related services provided at 143.dev, including account management, integrations, AI agent workflows, and supporting infrastructure.
Scope
These terms govern your use of the 143 website and hosted service at 143.dev, operated by Assembled, Inc. They do not govern the 143 open-source software itself - that is licensed under the MIT License and applies independently.
By using 143.dev, you agree to these terms. If you do not agree, do not use the service.
Eligibility
You must be at least 18 years old (or the age of majority in your jurisdiction, whichever is greater) to use the service. By using 143.dev, you represent that you meet this age requirement and have the legal authority to enter into these terms. If you are using the service on behalf of an Organization, you represent that you have the authority to bind that Organization to these terms.
The service
143 is an open-source platform that uses AI agents to analyze production issues and prepare code changes, validations, and pull requests. The hosted service at 143.dev provides a managed version of that platform, including account management, integrations, and infrastructure.
Accounts
You are responsible for maintaining the confidentiality of your account credentials, providing accurate account information, and using the service only as authorized by your organization and these terms. Organization administrators may control access to workspace content and settings for users in their organization.
Your content
You retain ownership of your code, prompts, repositories, issues, and other content. You grant us a limited, non-exclusive, worldwide license to host, store, transmit, reproduce, process, and create derivative works of that content solely as needed to operate, secure, and support the service. This includes transmitting content to third-party AI model providers for inference, generating and displaying output such as diffs, summaries, and pull requests in connected services such as GitHub, and caching or transforming content as necessary for service functionality. This license ends when you delete your content or terminate your account, except as required for backups, legal obligations, or legitimate security purposes.
AI-generated output
143 uses automated systems and third-party AI models to generate suggestions, diffs, summaries, and pull requests. AI-generated output may be incomplete, inaccurate, insecure, or unsuitable for your use case. You are responsible for reviewing, testing, approving, and deciding whether to use any output before relying on it in production.
We make no representation that AI-generated output is original, free of third-party intellectual property claims, or suitable for any particular licensing requirement. AI models may produce output that resembles existing copyrighted or open-source-licensed code. You are solely responsible for ensuring that any code you adopt complies with applicable licenses and does not infringe third-party rights. Assembled does not indemnify you against intellectual property claims arising from AI-generated output.
Third-party models and services
The service relies on third-party AI model providers, including Anthropic, OpenAI, OpenRouter, and Google, to process prompts and generate output. Your use of the service is also subject to the terms and policies of the providers whose models are used for your requests. If your organization supplies its own API keys, the provider's terms apply directly to that usage.
Data processing
If your use of the service involves processing personal data on behalf of your Organization, and applicable data protection laws (such as the GDPR, UK GDPR, or similar frameworks) require a data processing agreement, a Data Processing Addendum (DPA) is available upon request. Contact legal@assembled.com to request a DPA. Where a DPA is executed, it forms part of these terms and takes precedence to the extent of any conflict with these terms regarding the processing of personal data.
Acceptable use
You agree not to:
- Use the service to violate any applicable law or regulation
- Interfere with or disrupt the service or its infrastructure
- Attempt to gain unauthorized access to other users' accounts or data
- Use the service to transmit malware or malicious code
- Scrape, crawl, or index the service in a way that places undue burden on our infrastructure
- Use the service to exfiltrate secrets, access data without authorization, or interfere with another user, organization, or connected service
Open-source contributions
Contributions to the open-source repository are governed by the MIT License and the repository's CONTRIBUTING.md. Our contribution model is inbound=outbound: unless explicitly stated otherwise, contributions intentionally submitted for inclusion in the project are licensed under the same MIT License.
Trademarks
The MIT License grants rights to the software code but does not grant any rights to use Assembled's or 143's trademarks, service marks, trade names, logos, or branding. You may use the name "143" to truthfully describe your use of the software (for example, "built with 143" or "powered by 143"), but you may not use our trademarks in a way that suggests endorsement, affiliation, or sponsorship by Assembled without prior written consent. If you fork or modify the software, you must use your own branding and clearly distinguish your version from the official project.
Service availability
We aim to keep 143.dev available and reliable, but we do not guarantee uninterrupted access. The service is provided on an "as is" and "as available" basis. We may modify, suspend, or discontinue the service at any time.
Suspension and termination
You may stop using the service at any time. We may suspend or terminate access if you violate these terms, create security risk, or misuse the service. Termination of the hosted service does not affect your rights under the MIT License to use the open-source software on a self-hosted basis.
Disclaimer of warranties
To the maximum extent permitted by law, the service is provided without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. This is consistent with the MIT License under which the underlying software is distributed.
Limitation of liability
To the maximum extent permitted by law, Assembled, Inc. shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising out of or related to your use of the service. To the maximum extent permitted by law, our aggregate liability for all claims arising out of or related to the service will not exceed the greater of $100 USD or the amount you paid us for the service in the 12 months before the event giving rise to the claim.
Changes
We may update these terms from time to time. If we make material changes, we will notify you by updating the date at the top of this page. Continued use of the service after changes constitutes acceptance.
Dispute resolution
Any dispute arising from these terms or your use of the service will be resolved by binding individual arbitration administered under the rules of the American Arbitration Association in San Francisco, California. You agree to waive any right to participate in a class action, class-wide arbitration, or representative proceeding. Either party may seek injunctive relief in a court of competent jurisdiction to protect intellectual property rights.
Governing law
These terms are governed by the laws of the State of California, without regard to conflict of law principles.
Export controls and sanctions
You represent that you are not located in, or a national or resident of, any country subject to U.S. trade sanctions, and that you are not on any U.S. government list of prohibited or restricted parties. You will not use the service in violation of any applicable export control or sanctions laws.
Force majeure
Neither party will be liable for any failure or delay in performing its obligations under these terms (other than payment obligations) where such failure or delay results from causes beyond the affected party's reasonable control, including but not limited to natural disasters, pandemics, government actions, third-party service or infrastructure outages, internet disruptions, labor disputes, or acts of war or terrorism.
Assignment
You may not assign or transfer these terms or any rights or obligations under these terms without our prior written consent. We may assign these terms in connection with a merger, acquisition, corporate reorganization, or sale of all or substantially all of our assets. Any attempted assignment in violation of this section is void. Subject to the foregoing, these terms bind and inure to the benefit of the parties and their respective successors and permitted assigns.
Severability
If any provision of these terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions will continue in full force and effect. The invalid provision will be modified to the minimum extent necessary to make it valid and enforceable while preserving the parties' original intent.
Entire agreement
These terms, together with the Privacy Policy, and any applicable Data Processing Addendum, constitute the entire agreement between you and Assembled regarding the service and supersede all prior or contemporaneous agreements, proposals, or representations, whether written or oral, concerning their subject matter.
