scritty
scritty is a terminal emulator that captures attributable turns from supported coding CLIs into a searchable local corpus. Agents can query shared memory through MCP, while people can search through the terminal or CLI.
Best for: Relevant to developers searching prior decisions across supported agents while checking capture gaps and access scope.
- 02
Aura by Naridon
Aura provides an open-source desktop, CLI and MCP workspace for coding agents. It advertises semantic change history, plain-language diffs, function-level rewind and intent checks, with paid synchronization and collaboration features.
Best for: Relevant to developers inspecting agent changes and retaining Git-backed history across isolated worktrees.
- 03
Toolport
Toolport connects MCP servers to multiple AI clients through one local gateway, manages reconnection and OS-keychain credentials, and flags changed tools. Optional sharing synchronizes server configuration while credentials remain per user.
Best for: Relevant to developers sharing MCP configuration across agents and devices without sharing upstream secret values.
- 04
Ito
Ito builds a disposable copy of a web application for a pull request and uses agents to exercise affected flows. Findings return to the PR with logs, video or screenshots and reproduction details; fixes trigger another test run.
Best for: Relevant to teams reviewing execution evidence alongside human code review and existing tests.
- 05
Polygres
Polygres adds graph, vector, full-text and hybrid retrieval over PostgreSQL for AI context. Developers can host a database or synchronize selected existing data, explore retrieval in a playground and use a CLI or Python SDK.
Best for: Relevant to developers building retrieval grounded in Postgres data and relationships.
- 06
Muse Code
Muse Code is Meta’s terminal coding agent powered by Muse Spark. Its official page describes coordinated agents, auditable actions and multimodal coding work, with installation available for macOS and Windows.
Best for: For developers who want a terminal coding workflow and can review agent actions and generated changes.
- 07
GitHub Copilot
GitHub Copilot is GitHub's AI coding agent suite spanning IDE completion, chat, agent mode, code review, CLI, and cloud agents. Individual plans meter GitHub AI Credits for chat and agent usage while Free offers limited access and paid tiers raise credit allotments.
Best for: Developers who want Copilot embedded in GitHub workflows from local IDE assistance through cloud agents.
- 08
Mailgent
Mailgent provisions agent email, a credential vault, TOTP, calendar and signed identity through API or MCP. Paid tiers add USDC wallet payments, with scope-gated keys for individual capabilities.
Best for: Relevant to developers giving an agent narrowly scoped access to owned accounts and approved communications.
- 09
Token Harbor
Token Harbor exposes several model providers through one OpenAI-compatible API with free routes and paid usage passes. Users choose model IDs, review usage allowances and decide whether calls pause or continue from a paid balance at the pass limit.
Best for: Relevant to developers comparing model routes while controlling allowance exhaustion and data handling.
- 10
Superset
Superset orchestrates independent coding agents in Git worktrees with terminal sessions and change review. Paid features include remote access, recurring agent tasks and an iPhone/iPad app for monitoring agents and inspecting diffs.
Best for: Relevant to developers reviewing each agent’s changes and tests before merging branches or giving automation repository permissions.
