# Atlas vs Fine.dev: Terminal AI Coding Agents in 2026 > Atlas provides a terminal-native TUI with a free core and local Ollama embeddings, while Fine.dev offers asynchronous cloud agents and prebuilt libraries, with custom agents quoted from $500 per In 2026, developers choosing between terminal AI coding agents will find Atlas offers a free core, terminal-native TUI with robust local code indexing and permission-gated tool calls, contrasting with Fine.dev's asynchronous cloud-based agent platform, which includes prebuilt agents and cloud dev environments. ## Pick Atlas if - You require a terminal-native TUI that runs directly in your shell. - You prioritize local code processing and data privacy, with support for local Ollama embeddings. - You need explicit approval for every code change and permission-gated tool calls. - You seek a free core agent and prefer to bring your own model keys. - You value deep integration with git workflows, including staging and committing changes. ## Pick the other tool if - You prefer an asynchronous, cloud-based development environment for your agents. - You need prebuilt agents for specific stacks like FastAPI, React, or Terraform (roughly 12 available). - You are comfortable with custom agent costs starting from $500 per month each. - You prioritize agents that compile and test code automatically in a cloud environment. ## Deployment Model and Data Privacy Considering deployment models in 2026, Atlas operates as a terminal-native TUI that runs directly in your shell, offering robust local data privacy by supporting local Ollama embeddings. In contrast, Fine.dev's agents run asynchronously in a cloud dev environment, which may introduce different considerations for data residency and control. Atlas distinguishes itself as a terminal-native AI coding agent, providing a Text User Interface (TUI) that executes directly within your existing shell environment. This architecture ensures that core operations and code processing occur locally. A key privacy feature of Atlas is its ability to build its code index with local Ollama embeddings, which means sensitive code never leaves your local machine or third-party servers. This approach offers developers maximum control over their intellectual property and data. Atlas ships as a single self-contained binary, simplifying deployment and management for individual developers and teams. Conversely, Fine.dev is designed as an asynchronous agent platform that operates within a cloud development environment. Its agents branch, edit, and run code entirely in the cloud, which then culminates in opening a pull request. While this cloud-centric model offers convenience for some workflows, it inherently means that your code and development environment reside on external servers, a significant difference from Atlas's local-first design. ## Agent Customization and Pricing Transparency Regarding agent customization and cost, Atlas offers a free core and allows users to bring their own model keys, providing a flexible and cost-effective entry point in 2026. Fine.dev, however, quotes custom agents from $500 per month each, an order of magnitude above per-seat review tooling, and its base plan pricing is not discoverable on the vendor site. Atlas provides a highly accessible pricing model, featuring a free core that allows developers to get started without upfront costs. Users are encouraged to bring their own model keys, offering flexibility in choosing AI models and providers based on their specific needs and budget. Atlas is also extensible through plugins that contribute tools and hook into agent lifecycle events, enabling deep customization without additional per-agent fees. It connects to Model Context Protocol servers and exposes their tools to the agent, further enhancing its adaptability. In stark contrast, Fine.dev's pricing structure presents significant barriers to transparency and affordability for custom solutions. While it offers a public agent library with roughly 12 ready-made agents, the cost for custom agents is quoted from $500 per month each, plus an additional $10 per month per agent for extra compute. Furthermore, Fine.dev's base plan pricing is not publicly listed or discoverable on its vendor site, making it challenging for potential users to estimate overall costs for their teams. ## Code Change Review and Safety Mechanisms For code change review and safety in 2026, Atlas implements a multi-stage approval process, including explicit diffs and permission-gated tool calls, ensuring developers maintain granular control. Fine.dev's agents, while testing code in the cloud, primarily surface changes by opening a pull request after execution. Atlas prioritizes developer control and safety through a meticulously designed code change review process. Atlas drafts a plan in a read-only plan agent and asks before switching to a build agent, giving developers an initial opportunity to review the proposed actions. Crucially, Atlas computes a unified diff for every file edit and surfaces it for approval before writing, ensuring that every modification is transparent and explicitly sanctioned by the user. Furthermore, every Atlas tool call is permission-gated against allow, ask, and deny rules before it runs, preventing unintended operations. Atlas also reads git branches, status, and diffs, and can stage and create commits on your behalf, and snapshots file changes as git patches so edits can be diffed and rolled back. Fine.dev's approach to code changes involves agents running asynchronously end to end: they branch, edit, run the code in a cloud dev environment, and iterate until the task passes. The final output is then presented by opening a pull request. While Fine.dev's agents compile and test the app, the direct, step-by-step approval and permission gating seen in Atlas offer a different level of immediate oversight and control over the agent's actions. ## Agent Ecosystem and Public Traction When evaluating agent ecosystems in 2026, Fine.dev ships with roughly 12 ready-made agents for specific stacks, yet it exhibits the weakest public traction of its peer group, with no published benchmarks. Atlas, conversely, fosters extensibility through plugins and Model Context Protocol support, allowing for a more open and customizable agent environment. Fine.dev offers a public agent library that includes approximately 12 ready-made agents, covering popular stacks such as FastAPI, React, NestJS, Prisma, and Terraform. These prebuilt agents are designed to compile and test applications, iterating until a task passes. However, Fine.dev currently has the weakest public traction among its peer group, lacking published benchmarks and maintaining a barely-committed public agent repository. This limited public engagement can make it challenging for developers to assess its real-world performance and community support. Atlas, on the other hand, emphasizes an open and extensible ecosystem. It is extensible through plugins that contribute tools and hook into agent lifecycle events, allowing developers to tailor the agent's capabilities to their specific needs. Atlas also connects to Model Context Protocol servers and exposes their tools to the agent, promoting interoperability and broader integration possibilities. This plugin-based approach allows for a more dynamic and community-driven expansion of its capabilities, contrasting with Fine.dev's more curated, yet less publicly validated, library of agents. ## Code Indexing and Context Management For effective code understanding in 2026, Atlas employs advanced indexing methods, including AST declarations and hybrid semantic retrieval, and can use local Ollama embeddings. This contrasts with Fine.dev's implied cloud-based context management, which does not detail specific local indexing capabilities. Atlas utilizes sophisticated techniques for code indexing and context management to ensure accurate and relevant AI assistance. Atlas indexes code by AST declarations using tree-sitter, rather than relying on blind line windows, which provides a more structured and semantically aware understanding of the codebase. For search, Atlas searches code with hybrid semantic and keyword retrieval fused by reciprocal rank fusion, enhancing the precision and recall of code searches. A significant advantage for privacy and performance is that Atlas can build its code index with local Ollama embeddings, keeping code off third-party servers entirely. This local processing capability ensures that sensitive project data remains within the developer's control. Atlas also fans out work to subagents that can run in the foreground or in parallel background sessions, optimizing context utilization. Fine.dev's agents operate within a cloud dev environment, where they edit and run code. While this implies a form of context management within their cloud infrastructure, the specific mechanisms for code indexing, semantic retrieval, or the option for local embedding processing are not detailed in its public information, presenting a key difference in how code context is handled and secured. ## FAQ ### What is the primary difference in deployment between Atlas and Fine.dev in 2026?
