## Ellipsis

Ellipsis began as an AI reviewer that commented on GitHub pull requests, and has grown into a managed platform for running many kinds of coding agents in the cloud. The core idea is that an agent should be a file in your repository rather than a process on someone's machine: you describe the trigger, the prompt, the environment, the permissions and the budget in YAML, and Ellipsis provisions the compute to run it.

Agents can be wired to different harnesses and models. Switching between Claude Code and Codex, for example, is a matter of changing one block of configuration, so teams are not locked into a single model vendor. Triggers include pull request events, issue events, API calls from tools such as Linear, Slack, Sentry and Jira, and scheduled runs, which covers review bots, triage assistants, migration scripts and long-running background jobs alike.

Governance is built into the platform rather than bolted on. Each session receives credentials minted for that run and scoped to the repositories you allowed, then revoked with the sandbox. Spending caps can be set per session, day, week and month. Source code lives only inside the session sandbox and is deleted with it, while a session record of every command, tool call and file change is retained afterwards, so you can reconstruct what an agent did long after the machine is gone.

**Pricing & Plans:** Ellipsis offers a free trial and paid plans, with separate tailored options for enterprise and startup teams. The public pricing page lists platform access alongside use-case and enterprise tiers, and a demo can be booked for larger rollouts. Budgets for individual agent sessions are configurable per session, day, week and month, so consumption can be capped independently of the subscription tier.

- **Agents declared as YAML in your repo:** Define the trigger, prompt, environment, permissions and compute shape in a config file that lives alongside your code and is reviewed like any other change.
- **Managed, isolated infrastructure:** Ellipsis provisions and tears down virtual machines for each session, so agent work never depends on a developer's laptop being open or on hand-rolled runners.
- **Model and harness flexibility:** Choose Claude Code or Codex, or mix them, by editing a single configuration block rather than rewriting your automation.
- **Scoped credentials and zero source retention:** Credentials are minted per session and limited to the repositories you allowed, and source code is deleted together with the sandbox.
- **Session records and budget controls:** Review live sessions, replay every command and file change afterwards, and enforce spending limits per session, day, week and month.

**Strengths:** Agents are ordinary config files, so they are reviewable and versioned with your code; Model and harness choice is swappable without reworking the surrounding automation; Governance features - scoped credentials, budgets, audit trail - are built in from the start; Runs unattended in the cloud rather than tying up a developer's machine

**Limitations:** YAML-based configuration means a learning curve for teams used to GUI-only tools; Requires familiarity with coding agents and CI concepts to get the most out of it; Full enterprise terms and custom pricing are only available through a conversation

## Kiro

Kiro is a spec-driven coding platform from AWS that reframes AI assistance around intent rather than autocompletion. You describe what the software should do and supply context, and Kiro turns that into specifications that guide an agent through planning, implementation, testing, and review. Because requirements and design decisions are written down first, agents can check their results against what you actually asked for, and the platform deliberately enforces quality at each step so agents cannot silently skip a failing test.

The product spans multiple surfaces. Kiro IDE is the familiar desktop experience, the CLI installs with a single command and can run headless in CI/CD, and cloud sessions move long-running tasks off your laptop with parallel agents that keep working after you close the lid. Kiro Crew adds persistent agents that watch your backlog, codebase, or CI pipeline, triage incoming work, spawn specialized bots, and bring results back for your approval. It also meets you where work happens, whether that is Slack, Microsoft Teams, GitHub or GitLab issues and pull requests, or scheduled automation.

Underpinning this is persistent memory across sessions, shared team knowledge, and reusable steering so corrections do not need repeating. Workflows break large tasks into checked steps, property-based tests validate behavior across hundreds of cases, and adversarial review agents scrutinize diffs before a human approves. Kiro supports Claude, GPT, and open-weight models such as DeepSeek and Qwen, with an Auto mode that routes each task to a suitable model, and it is built on open standards including ACP, AGENTS.md, Skills, MCP, and Open VSX extensions.

**Pricing & Plans:** Kiro follows a freemium model with free usage to get started and paid tiers that add higher usage limits and credits for individual developers and teams. Enterprises can contact AWS for governance, SSO, compliance, and predictable pricing arrangements.

- **Specs that verify intent:** You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
- **Persistent agents and Crew:** Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.
- **Workflows and adversarial review:** Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.
- **Runs where you work:** Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.
- **Open standards and model choice:** Supports ACP, AGENTS.md, Skills, MCP, and Open VSX extensions, with Claude, GPT, and open-weight models via Auto routing.

**Strengths:** Spec-driven workflow ties generated code back to written requirements and design; Multiple surfaces including IDE, CLI, web, mobile, and cloud sessions; Persistent memory and shared steering reduce repeated corrections across sessions; Built and run by AWS with enterprise governance, SSO, and compliance backing

**Limitations:** Spec-first discipline adds upfront effort compared with prompting a chat assistant; Heavier sessions consume credits, so heavy usage can push you onto paid tiers; Tightest experience is with AWS and its surrounding ecosystem, which may not suit every stack
