Apache Maka

The Apache Software Foundation

Free

Apache-licensed local-first agent workspace that runs tools in a sandbox and records every model message and tool call as a recoverable execution log.

Key features

  • Append-Only Execution Record: Model messages, tool calls, tool results, permission decisions, and turn termination events are written down durably, so the transcript is evidence rather than a disposable chat buffer.
  • Context Trimming Without Data Loss: Old tool output can be omitted from the next prompt to shorten context while the full saved history remains intact and inspectable.
  • Single Runtime Host: Desktop, terminal, and evaluation all execute through one runtime, so behavior does not diverge between how you develop and how you benchmark.
  • Sandboxed Tool Boundary: Built-in Read, Write, Edit, Bash, Glob, and Grep tools run under a sandbox; anything leaving that boundary requires approval, and Computer Use and catalog skills are opt-in.
  • Crash Recovery and Resume: Runs can be aborted, failures are classified, and an interrupted turn can optionally be resumed rather than restarted from scratch.
  • Session Branching and Search: The desktop workspace supports creating, archiving, searching, renaming, retrying, regenerating, and branching sessions from any turn.
  • Bring Your Own Model: Connect a cloud API, a locally hosted model, or a compatible gateway, with streaming output, thinking, usage reporting, and clearer provider errors.
  • Declarative Evaluation Harness: maka eval expands multi-arm experiments into task by repetition by subject cells with immutable per-cell attempts and a result kernel covering score, normalized usage, attributable cost, duration, and failure reason.
  • Local-First Storage: Sessions, settings, artifacts, and run records stay on the machine by default, with local memory and optional web search when configured.

Best for

  • Auditable Agent Runs: Keeping a defensible record of exactly what an agent did and which permissions were granted during a task.
  • Long Coding Sessions: Working through a multi-turn refactor with branching and resume instead of losing state when a turn fails.
  • Agent Benchmarking: Running reproducible multi-arm experiments comparing models, prompts, or external agent subjects on the same task set.
  • Air-Gapped or Regulated Work: Running an agent workspace where sessions and artifacts must remain on local infrastructure.
  • Cost and Usage Analysis: Attributing token usage, cost, and duration per experiment cell to decide which model configuration to ship.
  • Terminal Workflows: Driving an agent from the current project directory or scripting a single non-interactive turn from CI or a shell.
  • Open-Source Agent Research: Building on a permissively licensed runtime whose execution semantics and architecture are fully documented.

Vela

Vela

Paid

AI scheduling assistant that books, coordinates, and manages meetings across email, SMS, WhatsApp, and phone.

Key features

  • Email and Messaging Integration: Accepts CC on email and direct messages via SMS or WhatsApp to start scheduling, reading message context to determine meeting intent and constraints.
  • Multi-Participant Coordination: Aggregates availability from all participants' calendars, proposes options in each participant's timezone, and negotiates times until consensus is reached.
  • Automated Follow-ups and Reminders: Automatically follows up with invitees who haven't responded, confirms bookings, and sends reminders to reduce no-shows and speed up scheduling.
  • Real-time Conflict Management: Monitors calendar availability continuously, detects conflicts or double bookings, and triggers automatic re-coordination and updated invites when changes occur.
  • Rescheduling and Change Handling: Handles cancellations and reschedules by re-coordinating with all stakeholders, updating invites, and notifying participants with minimal user intervention.
  • Enterprise-Scale Operations: Designed to manage thousands of meetings per week for organizations, with administrative controls and reporting to measure time saved and usage.
  • CC into email threads to delegate scheduling to the agent
  • Direct messaging via SMS and WhatsApp for scheduling requests
  • Phone call scheduling and outbound calling at scale
  • Real-time calendar availability sync to avoid double bookings
  • Timezone-aware time proposals for all participants
  • Automated follow-ups and reminders for non-responders
  • Automatic rescheduling and invite updates when conflicts arise
  • Handles multi-attendee and multi-round scheduling workflows
  • No separate links or logins required for participants
  • Designed for high-volume, parallel scheduling operations

Best for

  • Sales Discovery Calls: Automatically coordinate and book 30–60 minute discovery calls between sales reps and prospects across multiple timezones, reducing the back-and-forth email chains.
  • Customer Success Check-ins: Schedule recurring or ad-hoc CS meetings across stakeholders from customer and internal teams, handling reschedules and reminders to maximize attendance.
  • Cross-Functional Project Meetings: Organize multi-attendee planning sessions that require availability alignment across engineering, product, and design teams, negotiating times and updating calendars automatically.
  • Executive Scheduling at Scale: Manage an executive's calendar by filtering requests, proposing appropriate time slots, and coordinating assistants or multiple stakeholders without manual intervention.
  • Professional Services Coordination: For agencies and consultancies, consolidate client meeting requests via email or chat and handle all booking logistics, time zone conversions, and confirmations.
  • Event and Interview Scheduling: Coordinate interviewer panels and candidate availability, handle last-minute changes, and automatically update invites and reminders to reduce scheduling overhead.
  • Recruiting coordinator for scheduling candidate screens and full interview loops at scale
  • Sales and demo meeting scheduling across multiple stakeholders and timezones
  • Operations teams automating large batches of calls or meetings
  • Administrative replacement for executive assistants to manage calendars
  • Customer success teams coordinating cross-company stakeholder meetings
